Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock and not off the wood case. On the back plate of the clock movement there are some numbers such as 451-050 94cm. These simple numbers indicate everything there is to know about the mechanical clock movement itself.

Identification is the first step

When the numbers are matched from old to new, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of the existing clock components will fit just the same a it did before. Now troubleshooting can be done as well as part or movement ordering. When talking about the movement it will be clear what one is referred too.

A new Hermle clock movement is best

As discussed in a different section the new movement is the way to go. The new unit is a fraction of the price of an overhaul on the old one. The clock back and running in the shortest time instead of waiting months for the overhaul to be completed. The movement will last another 30 years without much complaint and this cant be said about a restored old unit.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Other Names Used

  • Hamilton
  • S. Larose
  • Mason & Sullivan
  • Welby
  • Pearl
  • Tally Industries
  • Bulova
  • Seth Thomas

340-020 Hermle Clock Movement

Clock Movement 340/341Timing A BalanceMovement NotesAbout Hermle MovementsHermle IDWhat Happened?Why get a new Hermle?Other Names Used

Please view these information tabs to learn more about the 340-020 and other Hermle Clock Movement 340/341 units

Timing a balance clock movement

Balance Clock Movement Timing is done fairly easy. There are three types clock balance movement styles used after 1950. This section is for those balance units that do not have a platform escapement. The platform escapement can be read about in another section. These notes are only for the larger balance wheel in the top center of the clock movement. This was used by Urgos 6/ series and many of the Hermle clock movements. Such as 340-020 and 350-020. Out of these you have two styles, the old style and then the new style. The old style was used all through the 70's and 80's and 90's. Around this time that they switched to the new style on the Hermle units and by this time the Urgos units were out of production.

The old style

The old style is one with a round spring that goes up and down (Vertical). It goes in a circle around the center arbor of the balance wheel. In this style there is a slide arm with a tiny weight on the balance wheel itself. There is a + and - on the wheel. To speed up time go towards the plus sign. However this style is not always easy to regulate and can be very hard to get it perfect. The factory has special devices to make it perfect. However it’s not that easy on the customer end with this style balance. For this reason it has been improved upon during future manufacturing.

If you have the old style balance then your clock movement has some age to it. If this is the situation you may want to replace the unit anyway. We have the movement brand new with the new style balance for less than the cost of a cleaning. Your clock movement has lasted you 25 years or more. In theory the new unit should last more than this with the improved aspects.

The new style

The units offered on this page all have the new and improved balance assemblies. Despite the change on the balance, these units are a direct fit and will install in the clock case the exact same way as the old unit. If the numbers match from the old unit to the numbers offered on this page, than the movement will be the exact same. It will be the same as it is now but brand new and with the improved balance.

The improved upon balance units have a different kind of hairspring (Horizontal). It will also have a screw to regulate it rather than a slider arm. The regulator screw is on the back of the movement near the balance. There is a + and - sign next to it meaning fast or slow. If the clock needs to be faster to keep time then the screw would be turned to the plus and opposite for slowing time.

Hermle clock 341 - 340 movement

Hermle clock 341 - 340 movement is such a popular little movement, so many sold, and for good reasons. It is compact and versatile, hard working and cost efficient. The movement will work 20 or 30 years night and day without much complaint.

Can fit into tight places, it can come in either a pendulum version or a balance wheel instead. The advantage of a balance wheel is there is no pendulum to put in beat, you can move it without readjusting the beat. Also with a balance wheel you never have to care if its level or not. The pendulum unit advantage is that louder tick tock sound. If the pendulum is visible through the glass it is a nice hypnotic thing to look at and listen to.

The Movement

A size 8 key winds up both the 340 and 341 clock movements, a single wind lasts 8 days. Ready for installation, the 340 and 341 Hermle clock movement series comes oiled and ready to go. Sold as the movement itself with its hand nut and hammers. If a pendulum unit, it will come with its suspension spring and leader. Already oiled Hermle 340 - 341 clock movement comes ready for installation.

The Chime

Westminster progressively playing each quarter hour, and the full song on the top of the hour. This is followed by the striking out of whatever the hour is. The hammer location on these units are on the bottom, with 5 hammer heads that strike chime rods. This aspect does not vary on these units, they are all consistent with the 5 hammer below attribute on all 340 and 341 movements.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Please view these information tabs to learn more about the 340-020 and other Hermle Clock Movement 340/341 units

Timing a balance clock movement

Balance Clock Movement Timing is done fairly easy. There are three types clock balance movement styles used after 1950. This section is for those balance units that do not have a platform escapement. The platform escapement can be read about in another section. These notes are only for the larger balance wheel in the top center of the clock movement. This was used by Urgos 6/ series and many of the Hermle clock movements. Such as 340-020 and 350-020. Out of these you have two styles, the old style and then the new style. The old style was used all through the 70's and 80's and 90's. Around this time that they switched to the new style on the Hermle units and by this time the Urgos units were out of production.

The old style

The old style is one with a round spring that goes up and down (Vertical). It goes in a circle around the center arbor of the balance wheel. In this style there is a slide arm with a tiny weight on the balance wheel itself. There is a + and - on the wheel. To speed up time go towards the plus sign. However this style is not always easy to regulate and can be very hard to get it perfect. The factory has special devices to make it perfect. However it’s not that easy on the customer end with this style balance. For this reason it has been improved upon during future manufacturing.

If you have the old style balance then your clock movement has some age to it. If this is the situation you may want to replace the unit anyway. We have the movement brand new with the new style balance for less than the cost of a cleaning. Your clock movement has lasted you 25 years or more. In theory the new unit should last more than this with the improved aspects.

The new style

The units offered on this page all have the new and improved balance assemblies. Despite the change on the balance, these units are a direct fit and will install in the clock case the exact same way as the old unit. If the numbers match from the old unit to the numbers offered on this page, than the movement will be the exact same. It will be the same as it is now but brand new and with the improved balance.

The improved upon balance units have a different kind of hairspring (Horizontal). It will also have a screw to regulate it rather than a slider arm. The regulator screw is on the back of the movement near the balance. There is a + and - sign next to it meaning fast or slow. If the clock needs to be faster to keep time then the screw would be turned to the plus and opposite for slowing time.

Hermle clock 341 - 340 movement

Hermle clock 341 - 340 movement is such a popular little movement, so many sold, and for good reasons. It is compact and versatile, hard working and cost efficient. The movement will work 20 or 30 years night and day without much complaint.

Can fit into tight places, it can come in either a pendulum version or a balance wheel instead. The advantage of a balance wheel is there is no pendulum to put in beat, you can move it without readjusting the beat. Also with a balance wheel you never have to care if its level or not. The pendulum unit advantage is that louder tick tock sound. If the pendulum is visible through the glass it is a nice hypnotic thing to look at and listen to.

The Movement

A size 8 key winds up both the 340 and 341 clock movements, a single wind lasts 8 days. Ready for installation, the 340 and 341 Hermle clock movement series comes oiled and ready to go. Sold as the movement itself with its hand nut and hammers. If a pendulum unit, it will come with its suspension spring and leader. Already oiled Hermle 340 - 341 clock movement comes ready for installation.

The Chime

Westminster progressively playing each quarter hour, and the full song on the top of the hour. This is followed by the striking out of whatever the hour is. The hammer location on these units are on the bottom, with 5 hammer heads that strike chime rods. This aspect does not vary on these units, they are all consistent with the 5 hammer below attribute on all 340 and 341 movements.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it. But as you see, since its a modern day unit (Post War German) it can be available new for a very good price. So what happens is you get a new movement instead of a fixed up old one, you get it in 3 days instead of 6 months. You will save hundreds of dollars doing it also.

 

Movement grades

All the Hermle clock movements a href="https://www.clockworks.com/">clockworks.com offers is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade. Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series. Please know that a href="https://www.clockworks.com/">clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will receive

Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also. If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader). If its a weight driven clock, it will come with new chains or cables and with pulleys. So this will be the movement with its hammer assemble on. This is the complete movement that comes out after you get in your hands and walk away from the clock with it. No weights, pendulum, chime block, hands, dial all this you have already usually.

Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock and not off the wood case. On the back plate of the clock movement there are some numbers such as 451-050 94cm. These simple numbers indicate everything there is to know about the mechanical clock movement itself.

Identification is the first step

When the numbers are matched from old to new, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of the existing clock components will fit just the same a it did before. Now troubleshooting can be done as well as part or movement ordering. When talking about the movement it will be clear what one is referred too.

A new Hermle clock movement is best

As discussed in a different section the new movement is the way to go. The new unit is a fraction of the price of an overhaul on the old one. The clock back and running in the shortest time instead of waiting months for the overhaul to be completed. The movement will last another 30 years without much complaint and this cant be said about a restored old unit.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock and not off the wood case. On the back plate of the clock movement there are some numbers such as 451-050 94cm. These simple numbers indicate everything there is to know about the mechanical clock movement itself.

Identification is the first step

When the numbers are matched from old to new, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of the existing clock components will fit just the same a it did before. Now troubleshooting can be done as well as part or movement ordering. When talking about the movement it will be clear what one is referred too.

A new Hermle clock movement is best

As discussed in a different section the new movement is the way to go. The new unit is a fraction of the price of an overhaul on the old one. The clock back and running in the shortest time instead of waiting months for the overhaul to be completed. The movement will last another 30 years without much complaint and this cant be said about a restored old unit.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units.

351-020 Hermle Clock Movement

Hermle Clock Movement 350/351MVT NotesHermle IDTiming A BalanceWhat Happened?Why get a new Hermle?Other Names Used

Please view these information tabs to learn more about the 351-020 and other Hermle Clock Movement 350/351 units

Hermle clock 351 - 350 movement

Hermle clock 351 - 350 movement is a popular movement for the bracket style shelf mantle clock. Its basically the same clock movement as the 341 series except the plate size is 20mm bigger. Such as the 341-020 compared to the 351-020. Or the 340-020 compared to the 350-020 are the same unit, but the plate size. The 351 and 350 has larger outer plates overall. However they are not cross compatible because the winding arbors are not quite the same. So the dial on one will not fit a the other movement.

The movement

The 351 - 350 movement Hermle clock series has Westminster chime and with a 120mm square outer plate size. It comes in a pendulum version such as the 351-020 or the non pendulum balance wheel version like the 350-020. The balance kind just has a balance wheel more like a watch on the top of the movement that acts as the escapement.

This is beneficial in that it cant be out of beat and its fine to be off level. Also to move from here to there with no reset up of the clock. All of these Hermle clock 351 - 350 movements take a key size 8 to wind them up and the run time is 8 days in a single wind. These units are all spring driven with the exception being the 351-830 and 351-850. Those units are special as they have two springs and one weight for the center. Often the center weight will be split into two weights on a yoke.

The hammers

The hammer locations are variable on this series. The 5 hammer bottom strike 351-020 pendulum, or 350-020 balance units are the most used, the movement does not take much depth and so it can be put into a shallow clock case no problem. Same with the side strike 5 hammer units like the 351-030, it fits into a shallow depth well. Other hammer locations are the back 4 on one side and 4 on the other like the 351-050 unit. Then lastly as in the 351-060 unit you can have 5 hammers diagonally on the back instead.

The chime

This is a Westminster chime unit. What this means is it will play Westminster progressively as it runs through the quarter hours. On the top of the hour we get to celebrate with the entire song and then it will strike out whatever hour it is.

Placing an order

The movement come as the movement itself with its hand nut, comes with the suspension spring and leader if its the pendulum style Hermle clock 351 - 350 movement. The movement will come already oiled and ready to go. It will come with instructions by email, if you get stuck you can just ask us to help if you have issues beyond the instructions. This family has been working on clocks for literally 100 years, if you have a question, just ask us! And it does not matter if the clock movement is out of warranty either, even years after it does not matter. The factory warranty on this unit is 3 years.

Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock and not off the wood case. On the back plate of the clock movement there are some numbers such as 451-050 94cm. These simple numbers indicate everything there is to know about the mechanical clock movement itself.

Identification is the first step

When the numbers are matched from old to new, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of the existing clock components will fit just the same a it did before. Now troubleshooting can be done as well as part or movement ordering. When talking about the movement it will be clear what one is referred too.

A new Hermle clock movement is best

As discussed in a different section the new movement is the way to go. The new unit is a fraction of the price of an overhaul on the old one. The clock back and running in the shortest time instead of waiting months for the overhaul to be completed. The movement will last another 30 years without much complaint and this cant be said about a restored old unit.

Timing a balance clock movement

Balance Clock Movement Timing is done fairly easy. There are three types clock balance movement styles used after 1950. This section is for those balance units that do not have a platform escapement. The platform escapement can be read about in another section. These notes are only for the larger balance wheel in the top center of the clock movement. This was used by Urgos 6/ series and many of the Hermle clock movements. Such as 340-020 and 350-020. Out of these you have two styles, the old style and then the new style. The old style was used all through the 70's and 80's and 90's. Around this time that they switched to the new style on the Hermle units and by this time the Urgos units were out of production.

The old style

The old style is one with a round spring that goes up and down (Vertical). It goes in a circle around the center arbor of the balance wheel. In this style there is a slide arm with a tiny weight on the balance wheel itself. There is a + and - on the wheel. To speed up time go towards the plus sign. However this style is not always easy to regulate and can be very hard to get it perfect. The factory has special devices to make it perfect. However it’s not that easy on the customer end with this style balance. For this reason it has been improved upon during future manufacturing.

If you have the old style balance then your clock movement has some age to it. If this is the situation you may want to replace the unit anyway. We have the movement brand new with the new style balance for less than the cost of a cleaning. Your clock movement has lasted you 25 years or more. In theory the new unit should last more than this with the improved aspects.

The new style

The units offered on this page all have the new and improved balance assemblies. Despite the change on the balance, these units are a direct fit and will install in the clock case the exact same way as the old unit. If the numbers match from the old unit to the numbers offered on this page, than the movement will be the exact same. It will be the same as it is now but brand new and with the improved balance.

The improved upon balance units have a different kind of hairspring (Horizontal). It will also have a screw to regulate it rather than a slider arm. The regulator screw is on the back of the movement near the balance. There is a + and - sign next to it meaning fast or slow. If the clock needs to be faster to keep time then the screw would be turned to the plus and opposite for slowing time.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

If this is the situation please just give us a call 800 381 7458. There is an extra fee for the regearing of the movement. Usually this fee is $30 to $40 additional.

Conclusion

Replacing a movement is less costly than a overhaul. These movements last 25 years before needing an over haul, but since its still being made at a fair price it is so much better just to replace. The clock will be problem free right away instead of months, last longer than a overhaul and comes oiled.

Clock movement 1151 Series by Hermle

Hermle clock movement 1151 series is a triple chime unit. It is the most produced triple chime, chain driven unit ever made. These clock movements can work night and day for 30 years sometimes without a sweat. The customers who order this movement originally purchased there clock in the 1970's through the 1990's.

The movement

Hermle clock movement 1151 series are all square movements. The are all with a 120mm plate size and in triple chime. The hand shaft length was made in two different lengths. The 1151-050 has the 32.3mm hand shaft while the 1151-053 has the longer 53.2mm hand shaft. The unit is a triple chime movement and is always chain driven. There are 12 hammers on the back side of the unit with 4 on one side and 8 on the other side. There was a time on these units that it came with a calendar function but these are not common. This is the same unit as the 451 series but with triple chime instead.

Does not come with

If you purchase the movement, you will receive just that, the movement alone. It will not come with the dail, chimeblock, weights or pendulum. All these things we have available, but if you get the movement only, you are ordering the movement and not the complete kit.

Comes with

The movement will come as the same movement, no knockoffs, made in Germany. The unit will be already oiled and will come with instructions and support. Basically everything that comes out with the two screws underneath, that entire gear ball with its hammers attached. The movement will come with new chains, its leader, hand nut and suspension spring.

The chime songs

This is a quarterly chime unit that will play a song every quarter hour, and then at the top of the hour it will strike out whatever hour it is.

Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock and not off the wood case. On the back plate of the clock movement there are some numbers such as 451-050 94cm. These simple numbers indicate everything there is to know about the mechanical clock movement itself.

Identification is the first step

When the numbers are matched from old to new, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of the existing clock components will fit just the same a it did before. Now troubleshooting can be done as well as part or movement ordering. When talking about the movement it will be clear what one is referred too.

A new Hermle clock movement is best

As discussed in a different section the new movement is the way to go. The new unit is a fraction of the price of an overhaul on the old one. The clock back and running in the shortest time instead of waiting months for the overhaul to be completed. The movement will last another 30 years without much complaint and this cant be said about a restored old unit.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Other Names Used

  • Hamilton
  • S. Larose
  • Mason & Sullivan
  • Welby
  • Pearl
  • Tally Industries
  • Bulova
  • Seth Thomas
  • Howard Miller
  • Sligh

Please view these information tabs to learn about Hermle Clock Movement 140/141 series.

Hermle 140 / 141 Clock Movement

Hermle 140 / 141 Clock Movement comes in either the pendulum or non pendulum styles. Such as the pendulum unit 141-040 or the non pendulum balance wheel version such as the 140-010. This is a fourteen day unit, it runs the 14 days on a single wind up. They used to be made to run 8 days only. If the numbers are with a 5 instead like 151 or 150-xxx its an 8 day wind. All they did to make this happen was put a longer mainspring in the barrel, so if you have a 151 or 150 unit, the new unit to replace this is a 141 or 140-xxx instead. The rest of the numbers are consistent with the old, just match them up.

Movement Details

Hermle 140 / 141 Clock Movement series are all spring driven with 85 x 98mm plate size. They all take a #8 size clock key. What is being offered on this page is the movement only with out the pendulum, gong or dial. It will come as the movement itself with its hand nut, and if a pendulum unit it comes with the suspension spring and leader. The 141-040, 141-030, and a 141-033 all comes with a calendar. It is required to remove this calendar if you do not have the days of the month on your dial. Its easy, its just removing excess things so its not so involved. See the other tab about how to remove your calendar.

The speed

The time from deciding to repair the clock, to having it done is the very least it could be.It will ship out the next business day, unless its a special gearing. If this is the situation it will take about 4 days to ship as the movement. This is because the movement comes apart and put together with special gears. You can tell if its a regear unit if it has an extra charge on the movement that cost more than the rest of the movements. The choice is clear to get the new one instead of overhauling the old unit. You would get the movement in a week or two instead of months later, it will cost about a third the amount of a typical overhaul charge also.

Clock Movement 141-040 141-070 Compatibility

The compatibility between the clock movement 141-040 and 141-070 needs explanation and clarification. At one point in time the same number was used for both versions .

What is the difference between the 040 and the 070 Hermle units? The 040 series has a one hammer on the back whereas the 070 units have two bells on the back.

It is common to get an 070 as a replacement for an 040 gong strike. This is because the two units are cross compatible. To make it a gong strike, you only need to remove one of the hammers with its wire and take off the bells. The reasoning behind this is simply the cost of importing the movements from Germany. There are minimum purchase requirements for each series. So it only makes sense to import one series that is cross compatible. In most cases the customer leaves the bells and ditches the gong as the sound is better.

What is even more confusing is that there was a time when the 141-070 had a gong strike or a bell strike. It was the same number for both types. So what was previously known as a 141-070 is now referred to as a 141-070141-040. So, if you have a 141-070 see if it has one hammer on the back that strikes a gong, or if it has bells on the back. If you have the bells get the 141-070 and if it has a gong order the 141-040.

Clock Movement Calendar Removal

This section is referring to the calendar versions of the Hermle clock movement 141-040 141-030 and 141-033

Many of these units come with a calendar as indicated by the letter K after the movement numbers. This is the usual way some movements are supplied by the manufacturer. This way it covers movements with and without a calendar. In this way only one style is to be made, shipped, and stored ready to ship. So sometimes the new movement only comes into the country with a calendar attached. The below information will enable you to remove the calendar portion if needed to do so for the installation. Such as if the calendar tube is in the way of installing the new movement to the dial.

Removal

If you look at the new movement you will see two hex nuts on the front of the clock holding a small plate with gears under it. You will see that your old unit does not have this. Take these hex nuts off, and the plate, and slide the big gear off of the hand shaft. This big gear is just for the calendar.

There is a small C clip that blocks the hour hand tube from coming off. Remove the C clip with a small flat screwdriver and the hour hand tube will come off. Do the same thing with your old unit and put the old unit hour hand tube on the new unit. Note the exact position of the new movement’s hour tube. This position is important to note before taking it off and put the old unit’s hour tube in the exact position. What is meant by position is the humps on the snail looking portion that is attached to the hour hand tube. This has to be the same position on the new one just like it was on the old. If it is not the same then the hourly strikes will be off. The deepest slot is 12 o’clock and the highest hump is 1 o’clock.

Post Removal

The mounting posts where the hex nuts were located are still on the clock movement. Now if these are in the way of mounting your movement to your dial, they would need to be removed. The clock movement calendar removal would require these to be snapped off. This may seem harsh but if you get a pair of pliers and bend them down and up, they will snap off. This is because these posts are only pressed in by machine and there is no other way to remove them. This is the intent of the factory to have done, when needed.

Strike Count Reset

It is time to test the strikes and see if they are correct and that you have the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If you have one o’clock and 12 o’clock strike correct its all set. Tf it strikes 1 and 12 out with the correct number of strikes, then the rest is ok also.

If this is too much information then you can send in the old unit and the new unit and we will swap it out at for a charge of $30 Plus shipping.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it. But as you see, since its a modern day unit (Post War German) it can be available new for a very good price. So what happens is you get a new movement instead of a fixed up old one, you get it in 3 days instead of 6 months. You will save hundreds of dollars doing it also.

 

Movement grades

All the Hermle clock movements a href="https://www.clockworks.com/">clockworks.com offers is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade. Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series. Please know that a href="https://www.clockworks.com/">clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will receive

Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also. If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader). If its a weight driven clock, it will come with new chains or cables and with pulleys. So this will be the movement with its hammer assemble on. This is the complete movement that comes out after you get in your hands and walk away from the clock with it. No weights, pendulum, chime block, hands, dial all this you have already usually.

Upon ordering

When you place your online order you will get a receipt emailed to you providing you put in the correct email address. If you do not get a receipt, please check your spam folder for the receipt from us. On the receipt is the link to click for the instructions for your product. The Hermle clock movement ships from Huntington, MA 01050 USA and sometimes from other locations also. The movements go out the next business day unless there is something we have to do to it such as a regear. The Hermle Clock Movements ship out UPS or sometimes FedEx. Never USPS unless there is a special request or you are an international customer.

Hermle Clock Pendulum Measuring

If the Hermle clock is not keeping time it maybe required to see if the correct pendulum is used by doing some measuring. The CM stamp will not be the actual pendulum length. The CM stamp will tell us certain things but not what the pendulum is supposed to be from tip to tip. This section describes what the CM stamp represents and how it is measured.

What the CM represents

Measuring a Hermle Clock Pendulum is done from the top of the movement and all the way down. The CM number will only be accurate to the pendulum length if the bob is the smallest diameter. A larger bob it will be a longer pendulum than what is indicated by the CM stamp on the movement. The larger or heavier the bob the longer the pendulum needs to be. If confused please email [email protected] for help determining the best pendulum length. Provide the CM number off the back plate and also how wide the pendulum bob is (round disk at the bottom of the pendulum).

Parts that are measured

The pendulum length (**cm) will be from the suspension post all the way down. Meaning to the bottom of the pendulum nut threads. The length includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring. This pendulum length will not always be exactly what is marked on the movement. There are other factors such as the pendulum bob diameter. The larger the pendulum bob diameter then the longer the pendulum length despite the CM length.

Conclusion

If the CM length on the old unit matches the CM length on the new unit it will keep time with the same pendulum. It maybe required to use the old leader and put it on the new unit but this is not common.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Hermle 140/141 seriesMVT Notes141-040 and 141-070Calendar RemovalAbout HermleCM NotesWhat Happened?Why get a new Hermle?Other Names Used

Please view these information tabs to learn about Hermle Clock Movement 140/141 series.

Hermle 140 / 141 Clock Movement

Hermle 140 / 141 Clock Movement comes in either the pendulum or non pendulum styles. Such as the pendulum unit 141-040 or the non pendulum balance wheel version such as the 140-010. This is a fourteen day unit, it runs the 14 days on a single wind up. They used to be made to run 8 days only. If the numbers are with a 5 instead like 151 or 150-xxx its an 8 day wind. All they did to make this happen was put a longer mainspring in the barrel, so if you have a 151 or 150 unit, the new unit to replace this is a 141 or 140-xxx instead. The rest of the numbers are consistent with the old, just match them up.

Movement Details

Hermle 140 / 141 Clock Movement series are all spring driven with 85 x 98mm plate size. They all take a #8 size clock key. What is being offered on this page is the movement only with out the pendulum, gong or dial. It will come as the movement itself with its hand nut, and if a pendulum unit it comes with the suspension spring and leader. The 141-040, 141-030, and a 141-033 all comes with a calendar. It is required to remove this calendar if you do not have the days of the month on your dial. Its easy, its just removing excess things so its not so involved. See the other tab about how to remove your calendar.

The speed

The time from deciding to repair the clock, to having it done is the very least it could be.It will ship out the next business day, unless its a special gearing. If this is the situation it will take about 4 days to ship as the movement. This is because the movement comes apart and put together with special gears. You can tell if its a regear unit if it has an extra charge on the movement that cost more than the rest of the movements. The choice is clear to get the new one instead of overhauling the old unit. You would get the movement in a week or two instead of months later, it will cost about a third the amount of a typical overhaul charge also.

Clock Movement 141-040 141-070 Compatibility

The compatibility between the clock movement 141-040 and 141-070 needs explanation and clarification. At one point in time the same number was used for both versions .

What is the difference between the 040 and the 070 Hermle units? The 040 series has a one hammer on the back whereas the 070 units have two bells on the back.

It is common to get an 070 as a replacement for an 040 gong strike. This is because the two units are cross compatible. To make it a gong strike, you only need to remove one of the hammers with its wire and take off the bells. The reasoning behind this is simply the cost of importing the movements from Germany. There are minimum purchase requirements for each series. So it only makes sense to import one series that is cross compatible. In most cases the customer leaves the bells and ditches the gong as the sound is better.

What is even more confusing is that there was a time when the 141-070 had a gong strike or a bell strike. It was the same number for both types. So what was previously known as a 141-070 is now referred to as a 141-070141-040. So, if you have a 141-070 see if it has one hammer on the back that strikes a gong, or if it has bells on the back. If you have the bells get the 141-070 and if it has a gong order the 141-040.

Clock Movement Calendar Removal

This section is referring to the calendar versions of the Hermle clock movement 141-040 141-030 and 141-033

Many of these units come with a calendar as indicated by the letter K after the movement numbers. This is the usual way some movements are supplied by the manufacturer. This way it covers movements with and without a calendar. In this way only one style is to be made, shipped, and stored ready to ship. So sometimes the new movement only comes into the country with a calendar attached. The below information will enable you to remove the calendar portion if needed to do so for the installation. Such as if the calendar tube is in the way of installing the new movement to the dial.

Removal

If you look at the new movement you will see two hex nuts on the front of the clock holding a small plate with gears under it. You will see that your old unit does not have this. Take these hex nuts off, and the plate, and slide the big gear off of the hand shaft. This big gear is just for the calendar.

There is a small C clip that blocks the hour hand tube from coming off. Remove the C clip with a small flat screwdriver and the hour hand tube will come off. Do the same thing with your old unit and put the old unit hour hand tube on the new unit. Note the exact position of the new movement’s hour tube. This position is important to note before taking it off and put the old unit’s hour tube in the exact position. What is meant by position is the humps on the snail looking portion that is attached to the hour hand tube. This has to be the same position on the new one just like it was on the old. If it is not the same then the hourly strikes will be off. The deepest slot is 12 o’clock and the highest hump is 1 o’clock.

Post Removal

The mounting posts where the hex nuts were located are still on the clock movement. Now if these are in the way of mounting your movement to your dial, they would need to be removed. The clock movement calendar removal would require these to be snapped off. This may seem harsh but if you get a pair of pliers and bend them down and up, they will snap off. This is because these posts are only pressed in by machine and there is no other way to remove them. This is the intent of the factory to have done, when needed.

Strike Count Reset

It is time to test the strikes and see if they are correct and that you have the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If you have one o’clock and 12 o’clock strike correct its all set. Tf it strikes 1 and 12 out with the correct number of strikes, then the rest is ok also.

If this is too much information then you can send in the old unit and the new unit and we will swap it out at for a charge of $30 Plus shipping.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it. But as you see, since its a modern day unit (Post War German) it can be available new for a very good price. So what happens is you get a new movement instead of a fixed up old one, you get it in 3 days instead of 6 months. You will save hundreds of dollars doing it also.

 

Movement grades

All the Hermle clock movements a href="https://www.clockworks.com/">clockworks.com offers is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade. Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series. Please know that a href="https://www.clockworks.com/">clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will receive

Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also. If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader). If its a weight driven clock, it will come with new chains or cables and with pulleys. So this will be the movement with its hammer assemble on. This is the complete movement that comes out after you get in your hands and walk away from the clock with it. No weights, pendulum, chime block, hands, dial all this you have already usually.

Upon ordering

When you place your online order you will get a receipt emailed to you providing you put in the correct email address. If you do not get a receipt, please check your spam folder for the receipt from us. On the receipt is the link to click for the instructions for your product. The Hermle clock movement ships from Huntington, MA 01050 USA and sometimes from other locations also. The movements go out the next business day unless there is something we have to do to it such as a regear. The Hermle Clock Movements ship out UPS or sometimes FedEx. Never USPS unless there is a special request or you are an international customer.

Hermle Clock Pendulum Measuring

If the Hermle clock is not keeping time it maybe required to see if the correct pendulum is used by doing some measuring. The CM stamp will not be the actual pendulum length. The CM stamp will tell us certain things but not what the pendulum is supposed to be from tip to tip. This section describes what the CM stamp represents and how it is measured.

What the CM represents

Measuring a Hermle Clock Pendulum is done from the top of the movement and all the way down. The CM number will only be accurate to the pendulum length if the bob is the smallest diameter. A larger bob it will be a longer pendulum than what is indicated by the CM stamp on the movement. The larger or heavier the bob the longer the pendulum needs to be. If confused please email [email protected] for help determining the best pendulum length. Provide the CM number off the back plate and also how wide the pendulum bob is (round disk at the bottom of the pendulum).

Parts that are measured

The pendulum length (**cm) will be from the suspension post all the way down. Meaning to the bottom of the pendulum nut threads. The length includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring. This pendulum length will not always be exactly what is marked on the movement. There are other factors such as the pendulum bob diameter. The larger the pendulum bob diameter then the longer the pendulum length despite the CM length.

Conclusion

If the CM length on the old unit matches the CM length on the new unit it will keep time with the same pendulum. It maybe required to use the old leader and put it on the new unit but this is not common.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

141-040K Hermle Clock Movement

The 141-040K Hermle Clock Movement runs 14 days on a single wind. This 141-040K Hermle Clock Movement is interchangable with the 151-040K 8 day day unit also. It has rear strike hammer(s) that will strike out the hours a the top of the hour, and strike once for the half hour. The 141-040K Hermle Clock Movement has a 85 x 98mm outer plate measurement. They all take a #8 size clock key.

Ordering a Hermle Clock Movement

The movement numbers off of the Hermle clock movement are needed when ordering. The numbers are matched up and it will be the exact same movement as the old one. Replacing the movement is a fraction of the price of a repair, and the clock will be up and working the fastest way.

Clock movement removal and installation

Removing and the installing the clock movement only requires the most basic tools. If you can change the spark plug on your lawn mower this will be a breeze. All the Hermle clock movements are in stock and can ship immediately. We are full time clock makers and retailers both, so if you need any assistance please ask. This goes for the installation or ordering a Hermle clock movement, if you need help please let us know.

Matching the CM when ordering

This note is only if your ordering a movement that has a pendulum. You will need to match up your CM length from the back plate of your old unit to the new one. The options indicated all that is available by stock. If there is a CM number you need but is not listed we can still create it most likely by changing some gears. If this is the situation please just give us a call 800 381 7458. There is an extra fee for the regearing of the movement. Usually this fee is $30 to $40 additional.

Conclusion

Replacing a movement is less costly than a overhaul. These movements last 25 years before needing an over haul, but since its still being made at a fair price it is so much better just to replace. The clock will be problem free right away instead of months, last longer than a overhaul and comes oiled.

Hermle 140 / 141 Clock Movement

Hermle 140 / 141 Clock Movement comes in either the pendulum or non pendulum styles. Such as the pendulum unit 141-040 or the non pendulum balance wheel version such as the 140-010. This is a fourteen day unit, it runs the 14 days on a single wind up. They used to be made to run 8 days only. If the numbers are with a 5 instead like 151 or 150-xxx its an 8 day wind. All they did to make this happen was put a longer mainspring in the barrel, so if you have a 151 or 150 unit, the new unit to replace this is a 141 or 140-xxx instead. The rest of the numbers are consistent with the old, just match them up.

Movement Details

Hermle 140 / 141 Clock Movement series are all spring driven with 85 x 98mm plate size. They all take a #8 size clock key. What is being offered on this page is the movement only with out the pendulum, gong or dial. It will come as the movement itself with its hand nut, and if a pendulum unit it comes with the suspension spring and leader. The 141-040, 141-030, and a 141-033 all comes with a calendar. It is required to remove this calendar if you do not have the days of the month on your dial. Its easy, its just removing excess things so its not so involved. See the other tab about how to remove your calendar.

The speed

The time from deciding to repair the clock, to having it done is the very least it could be.It will ship out the next business day, unless its a special gearing. If this is the situation it will take about 4 days to ship as the movement. This is because the movement comes apart and put together with special gears. You can tell if its a regear unit if it has an extra charge on the movement that cost more than the rest of the movements. The choice is clear to get the new one instead of overhauling the old unit. You would get the movement in a week or two instead of months later, it will cost about a third the amount of a typical overhaul charge also.

Clock Movement 141-040 141-070 Compatibility

The compatibility between the clock movement 141-040 and 141-070 needs explanation and clarification. At one point in time the same number was used for both versions .

What is the difference between the 040 and the 070 Hermle units? The 040 series has a one hammer on the back whereas the 070 units have two bells on the back.

It is common to get an 070 as a replacement for an 040 gong strike. This is because the two units are cross compatible. To make it a gong strike, you only need to remove one of the hammers with its wire and take off the bells. The reasoning behind this is simply the cost of importing the movements from Germany. There are minimum purchase requirements for each series. So it only makes sense to import one series that is cross compatible. In most cases the customer leaves the bells and ditches the gong as the sound is better.

What is even more confusing is that there was a time when the 141-070 had a gong strike or a bell strike. It was the same number for both types. So what was previously known as a 141-070 is now referred to as a 141-070141-040. So, if you have a 141-070 see if it has one hammer on the back that strikes a gong, or if it has bells on the back. If you have the bells get the 141-070 and if it has a gong order the 141-040.

Clock Movement Calendar Removal

This section is referring to the calendar versions of the Hermle clock movement 141-040 141-030 and 141-033

Many of these units come with a calendar as indicated by the letter K after the movement numbers. This is the usual way some movements are supplied by the manufacturer. This way it covers movements with and without a calendar. In this way only one style is to be made, shipped, and stored ready to ship. So sometimes the new movement only comes into the country with a calendar attached. The below information will enable you to remove the calendar portion if needed to do so for the installation. Such as if the calendar tube is in the way of installing the new movement to the dial.

Removal

If you look at the new movement you will see two hex nuts on the front of the clock holding a small plate with gears under it. You will see that your old unit does not have this. Take these hex nuts off, and the plate, and slide the big gear off of the hand shaft. This big gear is just for the calendar.

There is a small C clip that blocks the hour hand tube from coming off. Remove the C clip with a small flat screwdriver and the hour hand tube will come off. Do the same thing with your old unit and put the old unit hour hand tube on the new unit. Note the exact position of the new movement’s hour tube. This position is important to note before taking it off and put the old unit’s hour tube in the exact position. What is meant by position is the humps on the snail looking portion that is attached to the hour hand tube. This has to be the same position on the new one just like it was on the old. If it is not the same then the hourly strikes will be off. The deepest slot is 12 o’clock and the highest hump is 1 o’clock.

Post Removal

The mounting posts where the hex nuts were located are still on the clock movement. Now if these are in the way of mounting your movement to your dial, they would need to be removed. The clock movement calendar removal would require these to be snapped off. This may seem harsh but if you get a pair of pliers and bend them down and up, they will snap off. This is because these posts are only pressed in by machine and there is no other way to remove them. This is the intent of the factory to have done, when needed.

Strike Count Reset

It is time to test the strikes and see if they are correct and that you have the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If you have one o’clock and 12 o’clock strike correct its all set. Tf it strikes 1 and 12 out with the correct number of strikes, then the rest is ok also.

If this is too much information then you can send in the old unit and the new unit and we will swap it out at for a charge of $30 Plus shipping.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it. But as you see, since its a modern day unit (Post War German) it can be available new for a very good price. So what happens is you get a new movement instead of a fixed up old one, you get it in 3 days instead of 6 months. You will save hundreds of dollars doing it also.

 

Movement grades

All the Hermle clock movements a href="https://www.clockworks.com/">clockworks.com offers is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade. Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series. Please know that a href="https://www.clockworks.com/">clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will receive

Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also. If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader). If its a weight driven clock, it will come with new chains or cables and with pulleys. So this will be the movement with its hammer assemble on. This is the complete movement that comes out after you get in your hands and walk away from the clock with it. No weights, pendulum, chime block, hands, dial all this you have already usually.

Upon ordering

When you place your online order you will get a receipt emailed to you providing you put in the correct email address. If you do not get a receipt, please check your spam folder for the receipt from us. On the receipt is the link to click for the instructions for your product. The Hermle clock movement ships from Huntington, MA 01050 USA and sometimes from other locations also. The movements go out the next business day unless there is something we have to do to it such as a regear. The Hermle Clock Movements ship out UPS or sometimes FedEx. Never USPS unless there is a special request or you are an international customer.

Hermle Clock Pendulum Measuring

If the Hermle clock is not keeping time it maybe required to see if the correct pendulum is used by doing some measuring. The CM stamp will not be the actual pendulum length. The CM stamp will tell us certain things but not what the pendulum is supposed to be from tip to tip. This section describes what the CM stamp represents and how it is measured.

What the CM represents

Measuring a Hermle Clock Pendulum is done from the top of the movement and all the way down. The CM number will only be accurate to the pendulum length if the bob is the smallest diameter. A larger bob it will be a longer pendulum than what is indicated by the CM stamp on the movement. The larger or heavier the bob the longer the pendulum needs to be. If confused please email [email protected] for help determining the best pendulum length. Provide the CM number off the back plate and also how wide the pendulum bob is (round disk at the bottom of the pendulum).

Parts that are measured

The pendulum length (**cm) will be from the suspension post all the way down. Meaning to the bottom of the pendulum nut threads. The length includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring. This pendulum length will not always be exactly what is marked on the movement. There are other factors such as the pendulum bob diameter. The larger the pendulum bob diameter then the longer the pendulum length despite the CM length.

Conclusion

If the CM length on the old unit matches the CM length on the new unit it will keep time with the same pendulum. It maybe required to use the old leader and put it on the new unit but this is not common.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

What is the difference between the 040 and the 070 Hermle units? The 040 series has a one hammer on the back whereas the 070 units have two bells on the back.

It is common to get an 070 as a replacement for an 040 gong strike. This is because the two units are cross compatible.

There are minimum purchase requirements for each series. So it only makes sense to import one series that is cross compatible. In most cases the customer leaves the bells and ditches the gong as the sound is better.

What is even more confusing is that there was a time when the 141-070 had a gong strike or a bell strike. It was the same number for both types. So what was previously known as a 141-070 is now referred to as a 141-070141-040. So, if you have a 141-070 see if it has one hammer on the back that strikes a gong, or if it has bells on the back. If you have the bells get the 141-070 and if it has a gong order the 141-040.

Clock Movement Calendar Removal

This section is referring to the calendar versions of the Hermle clock movement 141-040 141-030 and 141-033

Many of these units come with a calendar as indicated by the letter K after the movement numbers. This is the usual way some movements are supplied by the manufacturer. This way it covers movements with and without a calendar. In this way only one style is to be made, shipped, and stored ready to ship. So sometimes the new movement only comes into the country with a calendar attached. The below information will enable you to remove the calendar portion if needed to do so for the installation. Such as if the calendar tube is in the way of installing the new movement to the dial.

Removal

If you look at the new movement you will see two hex nuts on the front of the clock holding a small plate with gears under it. You will see that your old unit does not have this. Take these hex nuts off, and the plate, and slide the big gear off of the hand shaft. This big gear is just for the calendar.

There is a small C clip that blocks the hour hand tube from coming off. Remove the C clip with a small flat screwdriver and the hour hand tube will come off. Do the same thing with your old unit and put the old unit hour hand tube on the new unit. Note the exact position of the new movement’s hour tube. This position is important to note before taking it off and put the old unit’s hour tube in the exact position. What is meant by position is the humps on the snail looking portion that is attached to the hour hand tube. This has to be the same position on the new one just like it was on the old. If it is not the same then the hourly strikes will be off. The deepest slot is 12 o’clock and the highest hump is 1 o’clock.

Post Removal

The mounting posts where the hex nuts were located are still on the clock movement. Now if these are in the way of mounting your movement to your dial, they would need to be removed. The clock movement calendar removal would require these to be snapped off. This may seem harsh but if you get a pair of pliers and bend them down and up, they will snap off. This is because these posts are only pressed in by machine and there is no other way to remove them. This is the intent of the factory to have done, when needed.

Strike Count Reset

It is time to test the strikes and see if they are correct and that you have the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If you have one o’clock and 12 o’clock strike correct its all set. Tf it strikes 1 and 12 out with the correct number of strikes, then the rest is ok also.

If this is too much information then you can send in the old unit and the new unit and we will swap it out at for a charge of $30 Plus shipping.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it. But as you see, since its a modern day unit (Post War German) it can be available new for a very good price. So what happens is you get a new movement instead of a fixed up old one, you get it in 3 days instead of 6 months. You will save hundreds of dollars doing it also.

 

Movement grades

All the Hermle clock movements a href="https://www.clockworks.com/">clockworks.com offers is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade. Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series. Please know that a href="https://www.clockworks.com/">clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will receive

Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also. If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader). If its a weight driven clock, it will come with new chains or cables and with pulleys. So this will be the movement with its hammer assemble on. This is the complete movement that comes out after you get in your hands and walk away from the clock with it. No weights, pendulum, chime block, hands, dial all this you have already usually.

Upon ordering

When you place your online order you will get a receipt emailed to you providing you put in the correct email address. If you do not get a receipt, please check your spam folder for the receipt from us. On the receipt is the link to click for the instructions for your product. The Hermle clock movement ships from Huntington, MA 01050 USA and sometimes from other locations also. The movements go out the next business day unless there is something we have to do to it such as a regear. The Hermle Clock Movements ship out UPS or sometimes FedEx. Never USPS unless there is a special request or you are an international customer.

Hermle Clock Pendulum Measuring

If the Hermle clock is not keeping time it maybe required to see if the correct pendulum is used by doing some measuring. The CM stamp will not be the actual pendulum length. The CM stamp will tell us certain things but not what the pendulum is supposed to be from tip to tip. This section describes what the CM stamp represents and how it is measured.

What the CM represents

Measuring a Hermle Clock Pendulum is done from the top of the movement and all the way down. The CM number will only be accurate to the pendulum length if the bob is the smallest diameter. A larger bob it will be a longer pendulum than what is indicated by the CM stamp on the movement. The larger or heavier the bob the longer the pendulum needs to be. If confused please email [email protected] for help determining the best pendulum length. Provide the CM number off the back plate and also how wide the pendulum bob is (round disk at the bottom of the pendulum).

Parts that are measured

The pendulum length (**cm) will be from the suspension post all the way down. Meaning to the bottom of the pendulum nut threads. The length includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring. This pendulum length will not always be exactly what is marked on the movement. There are other factors such as the pendulum bob diameter. The larger the pendulum bob diameter then the longer the pendulum length despite the CM length.

Conclusion

If the CM length on the old unit matches the CM length on the new unit it will keep time with the same pendulum. It maybe required to use the old leader and put it on the new unit but this is not common.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

Other Names Used

  • Hamilton
  • S. Larose
  • Mason & Sullivan
  • Welby
  • Pearl
  • Tally Industries
  • Bulova
  • Seth Thomas
  • Howard Miller
  • Sligh

Hermle Number Examples

Below are some typical examples of the Hermle clock movement numbering system. If your clock numbers are similar to this, its made by Hermle.

  • 451-050 94cm
  • 340-020
  • 140-070
  • 451-030 66cm

The options indicated all that is available by stock. If there is a CM number you need but is not listed we can still create it most likely by changing some gears. If this is the situation please just give us a call 800 381 7458. There is an extra fee for the regearing of the movement. Usually this fee is $30 to $40 additional.

Conclusion

Replacing a movement is less costly than a overhaul. These movements last 25 years before needing an over haul, but since its still being made at a fair price it is so much better just to replace. The clock will be problem free right away instead of months, last longer than a overhaul and comes oiled.

241-030 Hermle Clock Movement

Clock Movement 241Movement Notes241-040 Availability241-070 AvailabilityAbout HermleWhat Happened?Why get a new Hermle?Other Names Used

241-080 and other Hermle Clock Movement 241 units are described on these tabs.

Hermle 241 clock movement

Hermle 241 clock movement is a compact chain driven, two weight movement. This unit runs eight days on a single wind up and comes as a pendulum movement only. It is a nice clock for smaller floor clock models and works well in a shaker style case. It can also be used in wall clock cases such as a wag on the wall or Vienna style clock.

The movement

Chains, hand nut, leader and suspension spring are included with the clock movement. Weights, pendulum, dail, hands or chimeblock sold separately. This page is for the Hermle 241 clock movement alone as a replacement or to piece together a clock kit.

The installation

A simple clock movement to work with and is easy to swap out a worn out old unit. Once the hands and dial are off, things get easy. Two screws underneath the movement is all that is holding it in the clock case. There is only to get the weights and pendulum out of the way, there is two screws to deal with. Installation of course is just the reverse, comes with instructions for a couple set up steps and your done. If there is any road blocks during this simple process just contact us with your questions. We have been clock makers and clock repairmen for 100 years in this family. We can help long after the factory warranty is gone with your questions or if you need parts.

The speed

The speed of going from a broken clock to a working new movement is the shortest possible route. The alternate route is to have the movement overhauled. However this requires twice the price of the new one, and you will get back a used movement in 1 to 2 months later. The choice is pretty clear to just get the new unit and be done with the project. The movement will last another 25 years for less cost and quick. We ship everyday so it will go out the same day or the next business day from MA USA.

241-070 and 241-040 No longer made

Clock movement 241-070 and 241-040 is no longer available. These two weight, chain driven units were very popular in the clock world but they are now obsolete.

What to do?

We can overhaul the clock movement for you. However this is expensive and you would still be left with an old movement. It will cost around $500 and we will clean oil bush and polish the pivots. Test it and ship it back in about a month or two. This would be the best way to get the clock running if there was no alternative.

The best alternative

There is a clock movement in the 241 series that can be adapted to fit. The closest equivalent to that movement would be the Hermle 241-080. The only difference with this unit compared to your old unit is it will come with a bell on the top. This is instead of having a coil gong (or bells) on the back side of the movement. So you would remove the coil gong from your clock case because you will no longer need it. This new 241-080 Hermle clock movement will come with chains, hand nut, leader, and suspension spring.

Bell Strike

The new unit also comes with a bell on top included and installed, so now the clock will have a bell strike clock instead of a gong strike clock. Your clock weights and pendulum and clock hands will all the same as it was and these parts will work on your clock.

The bell strike sounds nice, it is more popular compared to the coil gong.

It is still best to get the new Clock movement 241-070 and 241-040 instead of chasing the old one. To have the old one overhauled instead would cost 2-3 times the price of the new one, and would still not last 25-30 years like the new one would. You get a brand new unit instead of a shined up old unit for a fraction of the price. Comes with instructions and support from a family with 100 years of clock making and clock repairing.

Clock movement 241-070 Conversion

The obsolete 241-070 two bell back unit can be replaced with the 241-080 one bell top clock movement. Instead of the bell or bells on the back of the movement it will now be on the top. The one bell top unit is the same in every other way. The plate size to part compatibility and so forth is the same, so its the best alternate unit. This means your clock weights and pendulum, dial, hands, mounts will all be the same.

The 241-070 was a popular unit for many years. It is a good thing there is something that makes a new unit, regardless of the bell location. The pendulum length most popular for the 241-070 was 94cm. This was measured from the top of the unit to the very bottom of the rating nut threads. This length is not stocked in the 94cm for 241-080 series but we make it up special. We take new gears we have here and swap them out in the new movement. These gears are in the time train and create the pendulum length where the clock will keep approximate time. So it is listed as an option on the drop down list but with a fee included in the price. The regear of the movement to match up with your old and hence be able to use the pendulum in its current length.

Conclusion

Conversion from old to new is still able to be done, despite the 241-070's obsolete status. The conversion only makes the clock movement have a bell on top instead of on the back. It is already oiled and comes with instructions for installation. Installation is easy on this series as its only held in with two screws underneath the clock movement. These screws go up into the pillar posts. The pillar posts on the bottom of the unit have threaded holes. Conversion from the 241-070 clock movement to the 241-080 is fast and simple.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the movement is the same. It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new one instead of chasing the old? The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.

Movements to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit that is close and easy to adapt. If it is not an easy one to adapt, or would take too much case work, then the best solution is to get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.

The movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have clockworks.com work on your movement for this fact alone. A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock comes with cables and pulleys, or chains, the leader, and suspension spring. This is everything that comes out when you remove the two screws that are under the movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

A new clock movement is typically less than half the cost of an overhaul. It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

350-020 Hermle Clock Movement

Hermle Clock Movement 350/351MVT NotesHermle IDTiming A BalanceWhat Happened?Why get a new Hermle?Other Names Used

Please view these information tabs to learn more about the 351-020 and other Hermle Clock Movement 350/351 units

Hermle clock 351 - 350 movement

Hermle clock 351 - 350 movement is a popular movement for the bracket style shelf mantle clock. Its basically the same clock movement as the 341 series except the plate size is 20mm bigger. Such as the 341-020 compared to the 351-020. Or the 340-020 compared to the 350-020 are the same unit, but the plate size. The 351 and 350 has larger outer plates overall. However they are not cross compatible because the winding arbors are not quite the same. So the dial on one will not fit a the other movement.

The movement

The 351 - 350 movement Hermle clock series has Westminster chime and with a 120mm square outer plate size. It comes in a pendulum version such as the 351-020 or the non pendulum balance wheel version like the 350-020. The balance kind just has a balance wheel more like a watch on the top of the movement that acts as the escapement.

This is beneficial in that it cant be out of beat and its fine to be off level. Also to move from here to there with no reset up of the clock. All of these Hermle clock 351 - 350 movements take a key size 8 to wind them up and the run time is 8 days in a single wind. These units are all spring driven with the exception being the 351-830 and 351-850. Those units are special as they have two springs and one weight for the center. Often the center weight will be split into two weights on a yoke.

The hammers

The hammer locations are variable on this series. The 5 hammer bottom strike 351-020 pendulum, or 350-020 balance units are the most used, the movement does not take much depth and so it can be put into a shallow clock case no problem. Same with the side strike 5 hammer units like the 351-030, it fits into a shallow depth well. Other hammer locations are the back 4 on one side and 4 on the other like the 351-050 unit. Then lastly as in the 351-060 unit you can have 5 hammers diagonally on the back instead.

The chime

This is a Westminster chime unit. What this means is it will play Westminster progressively as it runs through the quarter hours. On the top of the hour we get to celebrate with the entire song and then it will strike out whatever hour it is.

Placing an order

The movement come as the movement itself with its hand nut, comes with the suspension spring and leader if its the pendulum style Hermle clock 351 - 350 movement. The movement will come already oiled and ready to go. It will come with instructions by email, if you get stuck you can just ask us to help if you have issues beyond the instructions. This family has been working on clocks for literally 100 years, if you have a question, just ask us! And it does not matter if the clock movement is out of warranty either, even years after it does not matter. The factory warranty on this unit is 3 years.

  • Less cost than a cleaning in most cases
  • Should last 25-30 years, a repair would not
  • Easy to install, we can help if needed
  • Ships same day as order

Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock and not off the wood case. On the back plate of the clock movement there are some numbers such as 451-050 94cm. These simple numbers indicate everything there is to know about the mechanical clock movement itself.

Identification is the first step

When the numbers are matched from old to new, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of the existing clock components will fit just the same a it did before. Now troubleshooting can be done as well as part or movement ordering. When talking about the movement it will be clear what one is referred too.

A new Hermle clock movement is best

As discussed in a different section the new movement is the way to go. The new unit is a fraction of the price of an overhaul on the old one. The clock back and running in the shortest time instead of waiting months for the overhaul to be completed. The movement will last another 30 years without much complaint and this cant be said about a restored old unit.

Timing a balance clock movement

Balance Clock Movement Timing is done fairly easy. There are three types clock balance movement styles used after 1950. This section is for those balance units that do not have a platform escapement. The platform escapement can be read about in another section. These notes are only for the larger balance wheel in the top center of the clock movement. This was used by Urgos 6/ series and many of the Hermle clock movements. Such as 340-020 and 350-020. Out of these you have two styles, the old style and then the new style. The old style was used all through the 70's and 80's and 90's. Around this time that they switched to the new style on the Hermle units and by this time the Urgos units were out of production.

The old style

The old style is one with a round spring that goes up and down (Vertical). It goes in a circle around the center arbor of the balance wheel. In this style there is a slide arm with a tiny weight on the balance wheel itself. There is a + and - on the wheel. To speed up time go towards the plus sign. However this style is not always easy to regulate and can be very hard to get it perfect. The factory has special devices to make it perfect. However it’s not that easy on the customer end with this style balance. For this reason it has been improved upon during future manufacturing.

If you have the old style balance then your clock movement has some age to it. If this is the situation you may want to replace the unit anyway. We have the movement brand new with the new style balance for less than the cost of a cleaning. Your clock movement has lasted you 25 years or more. In theory the new unit should last more than this with the improved aspects.

The new style

The units offered on this page all have the new and improved balance assemblies. Despite the change on the balance, these units are a direct fit and will install in the clock case the exact same way as the old unit. If the numbers match from the old unit to the numbers offered on this page, than the movement will be the exact same. It will be the same as it is now but brand new and with the improved balance.

The improved upon balance units have a different kind of hairspring (Horizontal). It will also have a screw to regulate it rather than a slider arm. The regulator screw is on the back of the movement near the balance. There is a + and - sign next to it meaning fast or slow. If the clock needs to be faster to keep time then the screw would be turned to the plus and opposite for slowing time.

Mechanical Clock Movement Wear

Mechanical clock movement wear after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

What wear and where

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

Invisible clock movement wear

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement. The movement will run for another 5 or 15 years with no issues but then it will be time to do it again.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again. This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul could be anywhere from 1 to 3 months, and in some extreme cases, a year. It is a slow moving venture that costs twice as much as a new movement would. If a new movement is not available, then this is the best, and only, way to handle a clock repair.

Replacing with a new clock movement

If the movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old movement so that it is better than new.

The mechanical movement identification page will assist you with determining who made the clock. This is for post WW2 modern mechanical clock movements made in Germany only however.
