Clock Weight Hook

Brass top hook for modern German movements such as Hermle / Urgos / Kieninger. Comes either with external threads or internal threads. The M* number is the thread size of the screw/bolt, M4 is 4mm, M5 is 5mm.

Long High Torque Clock Hands #HTH7

High Torque hands are long hands that need to go on a high torque battery operated clock movement. The hands have the USA standard 'I' shaft mounting hole in the minute hand. What this means is the hour hand will have a round mounting hole and the minute hand will have an oblong hole. These hands are sold as a pair, and measured by the minute hand only from the center of the mounting hole to the end of the pointer side.

What Clock Parts To Send

  Please send the movement only along with a note saying how much each weight weighs (if weight driven) and your contact information. Read More »

Please do not send keys, dial, hands, chime block, weights or pendulum as we have them here in the shop.

We are not responsible for any clock case damage that is shipped to us. Please do not send the clock case.

Cleaning for $150

  Mechanical clocks need cleanings periodically. When clock movements come out of the factory, the factory will say oil your new clock movement in 5 years, clean and oil it in 10 years. However not many go by this rule and if you have a clock from the 1800s or early 1900s, think of how it must need a cleaning at this point. By cleaning, this does not mean making it pretty and shiny although that will most likely happen also. Rather what is meant by cleaning is to remove all the old oil that has dried up in the pivot holes, so new oil can be applied. This is not usually visible but where the pivots posts spin inside the outer plates, if there is too much old dried up oil it will cause the clock to stop running. What we offer to you is a cleaning of the movement with the best equipment available, with the best solutions available, and then a inspection of the movement. If the movement does not need bushings or disassembly or parts, we will oil it and test run it. Cost is $150 plus shipping back to you if that is all that is needed.

Clock Movement Removal

  To remove your movement to send it in for Clock Repair, take off the hands by holding the minute hand and turning the minute hand nut to the left. Read More »

Once this nut is off, the minute hand will come off. To get the hour hand off, twist it and pull it toward you and it will come off as it is only a friction fit.

Remove any weights or pendulum that may be on the clock. Take the screws out that hold the movement in place. In grandfather clocks, these would be on the bottom of the movement going up to the outside arbors; for mantle and wall clocks they would be toward the front or back of the case.

The dial on most grandfather clocks are either attached to the case or to the movement itself. If it is attached to the movement, unclip it off of the back side of the front plate of the movement.


CLEANING AND OILING FOR ONLY $150

We have the best tooling, cleaning equipment, and cleaning solutions. There is no expense spared by us when it comes to having the best equipment. With this factor and 3 generations of clock repair expertise, you can rest assure your clock works will be in the best hands it can be in. We will take the movement in, unpack it, and then clean it and inspect it for $150. If it passes inspection, we will oil it and test it. If this is all that is needed? that is all it will cost is the $150 plus the shipping back to you. The initial $150 is non refundable and is the fee for the cleaning, inspection, and oiling and testing only. We do need to be paid for our time on this even if the clock movement is deemed unrepairable for some reason.

HOW TO PACK IT UP

When packing up the movement, take special care to protect the hand shaft as this is hard to correct if it gets bent. This is the shaft that the hands go on to tell the time. You should pack the movement up well with newspaper and bubble wrap, or put the movement in a plastic bag and then use peanuts. If you use peanuts, please DO NOT let the movement get peanuts all up inside of it. Make sure you place the movement in the box with the hand shaft pointing up.

Once you have the movement packed really well in a box, pack it again in another box with more packing material. Double boxing provides extra cushion for the movement as it travels to minimize the possibility of damage.

WHERE TO SEND IT

After you have the movement alone packed up, please send it to: CLOCKWORKS 124 Goss Hill Rd, PO Box 339, Huntington MA 01050 USA. If you fill out the below form we will get notification about your clock coming and we will reply via email confirming your form submission.

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 you will see the numbers such as 451-050 94cm. These numbers let us know everything we need to know about the mechanical clock movement itself. This tells us if its weight driven, the plate size, and every other aspect of the movement.

When the numbers are matched, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of your existing clock components will fit just the same a it did.

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

Mechanical Clock Movement Issues

Mechanical Clock Movement Issues arise 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.

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.

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 Mechanical Movement Reasons

New Mechanical Movement Reasons to get the new one when we can just repair the old one? The reason is because it is still in production. Its still made in mass production in Germany, so this means its available for a lot less cost. Even the best repair job from the best repair professional, cannot make it as good as a new one.

New Mechanical Movement Reasons are because it can ship from USA the same day you order it. The time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement. All clock component parts such as weights will fit on to the new movement. The cost of a new movement is less and when it's installed it should last another 25-30 years without intense service. Over the years, if there is improvements that can be done on the movement, the factory updates them. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Conclusion

The new unit will cost less and ship now. It will be far better in every way than getting the old one restored. You will have a new movement in days instead of the used one back in months.

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.

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
  • 341-020 45cm
  • 1151-050 114cm
  • 451-053 94cm

  • 141-070 45cm
  • 351-050 55cm
  • 1161-850 94cm
  • 241-070 94cm

451 Hermle Clock Movement

The numbers on the back plate of the 451 Hermle Clock Movement is everything one needs to get a replacement. If the numbers match then the movement matches.

If the clock is a pendulum unit, be sure to select the proper CM length that matches the old unit.

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 Clock Movement Directory

HermleHermle Clock Movement Directory, Number starts with.....



Hermle Clock Movement Directory Explanation

Hermle Clock Movement Directory is to get to the correct page that contains your clock movement. The Hermle mechanical movements have numbers on the back plate starting with the below few numbers, and then followed by a - dash and then some more numbers. Examples = 340-020 131-070 1161-853 351-020 and similar. So if your clock says something like 1161-053 you would drop the second half and click the 1161 button below. This will bring you to the page where 1161-053 and the rest of the 1161 series resides.

If Not Listed

If your Hermle movement is not found on these pages we may still have it as a conversion or we maybe able to create it out of what exists. Please email your movement number or a picture of the back plate to [email protected] If your movement numbers do not look like the Hermle movement numbers as described it maybe made by someone else. 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.

Grandfather Clock Replacement Cable

Grandfather Clock Replacement Cable

This is the original factory replacement Clock Weights cable for German clock movements with installed cable ends. The cables are original and sometimes vary slightly in lengths.

Changing a Clock Cable

Changing a Clock Cable is done when the clock cable is broken and you order a new one from clockworks.com. This section describes how to swap out a broken clock cable with a new one. We are referring to post WW2 modern grandfather units of German origin in this section. However all have a similar method no matter what the cable driven clock your working with. The swapping is easy because there is a big hole and a little hole connected on the cable mount. The cable end fits into the big hole, and slides over to seat into the little hole. When locked in, its not going anywhere and seats in secure. This is the same basic theme on both ends of the cable, one slot being in the cable drum itself and the other on the movement.

While the movement is installed

In some few instances the strike or chime cable can be swapped without movement removal. You maybe able to remove the cable and reinstall it because the drums maybe accessible from the side access panels on the side of the case. Removal is done by lifting up the cable from its oblong hole and slide it over to the big side. One side of the cable is easy, the side that is attached to the movement itself. The other side of the cable goes into the drum itself and is removed the same way.

To get to the slot in the drum, you will need to spin it. The cable drum is made to spin in one direction only of course, so spin it until you see the slot for the end. There is a plastic cover over the drum sometimes, this can stay on usually. If you cant get at the drum to spin it and remove the cable, you will need to remove the movement.

Changing a Clock Cable - Movement Removed

Most times it is required to remove the movement from the clock case. This is described in another section. With the movement out it is so much easier. You can flip the movement over and spin the drums to remove the ends. Installation is reverse of course and upon reinstalling the movement its the normal set up of any clock.

340-020 Hermle Clock Movement

Clock Movement 340/341Timing A BalanceMovement NotesAbout Hermle MovementsHermle IDWhat Happened?Why New?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. 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.

 

All the Hermle clock movements we offer 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. To get the movement from someone besides clockworks.com, you may not know what one you will get. Please know that Clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will get

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.

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.

Mechanical Clock Movement Issues

Mechanical Clock Movement Issues arise 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.

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.

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 Mechanical Movement Reasons

New Mechanical Movement Reasons to get the new one when we can just repair the old one? The reason is because it is still in production. Its still made in mass production in Germany, so this means its available for a lot less cost. Even the best repair job from the best repair professional, cannot make it as good as a new one.

New Mechanical Movement Reasons are because it can ship from USA the same day you order it. The time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement. All clock component parts such as weights will fit on to the new movement. The cost of a new movement is less and when it's installed it should last another 25-30 years without intense service. Over the years, if there is improvements that can be done on the movement, the factory updates them. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Conclusion

The new unit will cost less and ship now. It will be far better in every way than getting the old one restored. You will have a new movement in days instead of the used one back in months.

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.

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 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
  • 341-020 45cm
  • 1151-050 114cm
  • 451-053 94cm
  • 1161-853 114cm
  • 141-070 45cm
  • 351-050 55cm
  • 1161-850 94cm
  • 241-070 94cm

340 - 341 Hermle Clock Movement

The numbers on the back plate of the 340 - 341 Hermle Clock Movement is everything one needs to get a replacement. If the numbers match then the movement will match.

If the clock is a pendulum unit, be sure to select the proper CM length that matches the old unit. For example it may say 341-020 45cm on the Hermle Clock Movement. If your clock movement has an A at the end such as 341-020A, just ignore the A.

The Hermle clock movement 340-020 is a Westminster Chime unit with five chime hammers below. This high quality spring driven German movement comes pre oiled and includes the improved balance system for ease of fine timing.

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 Clock Movement Directory Explanation

Hermle Clock Movement Directory is to get to the correct page that contains your clock movement. The Hermle mechanical movements have numbers on the back plate starting with the below few numbers, and then followed by a - dash and then some more numbers. Examples = 340-020 131-070 1161-853 351-020 and similar. So if your clock says something like 1161-053 you would drop the second half and click the 1161 button below. This will bring you to the page where 1161-053 and the rest of the 1161 series resides.

If Not Listed

If your Hermle movement is not found on these pages we may still have it as a conversion or we maybe able to create it out of what exists. Please email your movement number or a picture of the back plate to [email protected] If your movement numbers do not look like the Hermle movement numbers as described it maybe made by someone else. 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.

How to order

You will need CM number off of the Hermle clock movement itself. Not off the paper work, not off the wood case. It will say a number such as 94CM or 114CM, some number followed by CM (centimeters).

Measuring note = The Germans measure there pendulum length from the TOP of the movement and all the way down to the very bottom of the pendulum rating nut threads. This could make things confusing for the customer and also this measurements varys drastically depending on the bob diameter. So the length can be tricky but lucky for you, you do not need to know all this. If your clock says something like 94cm, just choose 94cm from the list with your desired bob diameter, and we will take care of the length. The reason why this is explained here, is sometimes a customer gets the pendulum and measures it, and says "hey this pendulum does not measure 94CM and therefore it is wrong" but this is not the situation. A pendulum FOR a Hermle 94cm movement, does not mean you will get a 94cm long pendulum, it will be shorter.

Bob note = If you do not have a pendulum your replacing and its lost, we need to also figure out what bob diameter will swing around inside the case without hitting the sides. Usually people want the largest bob diameter they can get without it hitting the sides of the case. So how we figure this out is to measure how wide the inside of the clock is where the pendulum will swing. You now have some measurement like 14.5 inches or something, we deduct 4 inches from this number = 6 1/2 inches is the widest bob diameter you would want to get. You can get whatever is smaller, but dont go larger. For example you do not want a 8 1/2 inch bob because it will hit the sides, but you can use a 5 1/2 inch or 6 1/2 inch bob just fine.

Here are the steps to order the pendulum =

  • 1. Know your movement is made by Hermle by seeing above movement number examples.
  • 2. Get the CM numbers off of the back plate of the movement itself.
  • 3. Determine the bob diameter needed by measuring how wide the inside of the case is and then subtracting 4 inches.
  • 4. Decide if you want a Metal fancy Lyre style pendulum, or a Wood stick pendulum, or a brass rod pendulum if the option is there. They all come with a brass round bob at the bottom in the diameter you choose, but what it hangs on can be any of those mentioned (lyre, stick, brass rod.)
  • 5. Order it
  • When you get your pendulum you will need to put your clock in beat for it to run. This is very easy.

    Please note, the picture is of a Hermle Lyre pendulum for a 114cm movement with twisted rods. If the pendulum is for a 94cm or shorter movement CM it will have straight rods instead.

Beat Setting Mechanical Clock Movements

Beat Setting Mechanical Clock Movements means the tick and the tock sound of the clock is evenly spaced in sound. Every pendulum clock that is mechanical needs to be put in beat to run. This is so simple but its amazing to me how many clocks in the world have not run for 10 years or more, just because this is not known. Often clocks in tag sales, auctions, homes, only needed to be put in beat to run but was left unused for years and years. The setting of the beat is easy, less than a minute to do, and the clock is fine again.

Every mechanical clock that has a pendulum needs to be in beat to function. Its part of owning the clock, is the learn this. If you do not know how to do this, whenever you move the clock from here to there it will stop after 5 - 10 minutes. Putting the clock in beat is very easy.

How to put a German mechanical clock in BEAT ? (Post 1950)

This is done on Modern German clocks by pushing the pendulum all the way to one side (doesn’t matter right or left) to go beyond its resistance, and then letting it go. Now listen to see if the tick and the tock are evenly spaced. If it is stick going ticktock ticktock, or even tocktick tocktick then it is not in beat and will stop after 5min to an hour. Repeat the process above of pulling the pendulum all the way to one side and letting it go. The clock should have a nice, steady, rhythmic tick-tock, tick-tock with equal time lapsing between the tick and the tock and the next tick.

Sometimes when there is not much room to swing the pendulum in the clock case, as there is a big round pendulum bob and the case is not wide, you will need to adjust the beat in a different way. This is also true on some movements that the beat will not automatically set when swinging the pendulum wide. You would adjust the beat by pushing the top of the pendulum left or right as it hangs in its clock case, just hold a lower portion of the pendulum with your left hand as you push the top of the pendulum left or right with your right hand. You will feel the freedom in the pendulum to move left or right, with some resistance at the sides at the end of your left or right travel. You are changing the beat of the clock when you go beyond this resistance and therefore changing the place of the freedom area. Don’t be afraid to move this pendulum top as there is nothing to break as you go left or right beyond the resistance on the sides of the swing.

Notes

The beat is the rhythmic pulsations of the escape wheel clicking over one tooth at a time, and this results in the sound tick / tock. What drives the pendulum is the escapement. They call it an escapement because its just letting the power of the gear train escape one tooth at a time. This make the sound tick and tock. That tick or tock sends a jumping pulse action to what is known as a crutch and that wacks the pendulum slightly each swing. The pendulums momentum back and forth, with being wacked by the crutch that comes down a little, just keeps it going and going. Provided its even left and right, in other words the tick and tock are even.

At this point, you have the movement in the clock with the dial off still. You have the movement running good. Now its time to make it chime and strike.

1161-853 Hermle Clock Movement

1161 Hermle Clock MovementMVT NotesHermle IdentificationWhat Happened?Other Names UsedWhy order a new movement?

Please view these information tabs to learn about the movement 1161-853 and other 1161 Hermle Clock Movement units

1161 Hermle Clock Movement Notes

The 1161 Hermle Clock Movement Notes is written for information about the clock you own. These movements are great that is why there is so many made. They work night and day for 30 years without much complaint. So here is some information on these fine German made units.

Names on the Movement

The name maybe a number of makers on the movement, but it was made by Hermle not them. It may say Howard Miller, or Ridgeway, or Sligh, or many other names. If the number on the clock movement starts with 1161- its really made by the Hermle company. They let these companies to have there name on the movement instead of Hermle.

Chain or Cable Drive

This movement was made in both cable driven and also chain driven styles. The 1161-853 is the most popular and the most produced Grandfather clock movement in the world. When ordering a new movement it will come with the chains or cables with the pulleys.

Hermle movement 1161-853 Clock Weights

This clock movement takes three clock weights to run. The weights should be close to 8 or 10lbs, and does not have to be exact. Even though it does not have to be the exact weight, here is the exact weight specification from the factory. If the pendulum bob is less than 8 1/2 inches wide, it will take two at 7.7LBS and one at 9.9LBS. If the pendulum bob is 8 1/2 inches in diameter or larger, it takes two weights at 9.9LBS and one at 7.7LBS. Often they will have a 10 1/2 inch bob with the two at 7.7 and one at 9.9 and the customer says it ran 30 years like that.

Weight Placement

The placement for the clock weights on this series is the following. The heavy weight will go on your right as you face the clock if one heavy and two light. If you have two heavy weights and one light weight, the light one will go on your left as you face the clock. So what this means is the middle time train weight is variable light or heavy depending on pendulum bob diameter.

1161 Hermle Clock Movement Songs

This is a triple chime unit that plays out a melody on the quarter hours and then on the top of the hour it will strike out whatever times the hour is. The songs this one plays are your choice of the following. Westminster, Saint Micheal, or Wittington and also a silent option. For an additional cost is it able to have an auto night shut off switch (ANSO), this will make the clock quiet from 10pm to 7am on its own without your intervention.

The Support

Please note the factory will give you three years for the warranty. However we are clock makers here at Clockworks.com and we have been doing this sort of thing for a long time in this family (over 100 years of experience). If you have some sort of question or concern in whatever amount of time, we are not going to turn you down in response, we answer whatever questions you have even a decade later, it really does not matter. We take care of our customers in whatever way we can. The movement comes with instructions and any questions beyond the instructions can be emailed, chatted, or called in.

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 you will see the numbers such as 451-050 94cm. These numbers let us know everything we need to know about the mechanical clock movement itself. This tells us if its weight driven, the plate size, and every other aspect of the movement.

When the numbers are matched, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of your existing clock components will fit just the same a it did.

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

Mechanical Clock Movement Issues

Mechanical Clock Movement Issues arise 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.

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.

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.

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.

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.

  • 1161-850 94cm
  • 241-070 94cm

New Mechanical Movement Reasons

New Mechanical Movement Reasons to get the new one when we can just repair the old one? The reason is because it is still in production. Its still made in mass production in Germany, so this means its available for a lot less cost. Even the best repair job from the best repair professional, cannot make it as good as a new one.

New Mechanical Movement Reasons are because it can ship from USA the same day you order it. The time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement. All clock component parts such as weights will fit on to the new movement. The cost of a new movement is less and when it's installed it should last another 25-30 years without intense service. Over the years, if there is improvements that can be done on the movement, the factory updates them. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Conclusion

The new unit will cost less and ship now. It will be far better in every way than getting the old one restored. You will have a new movement in days instead of the used one back in months.

341-020 Hermle Clock Movement

Clock Movement 340/341Timing A BalanceMovement NotesAbout Hermle MovementsHermle IDWhat Happened?Why New?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.

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.

 

All the Hermle clock movements we offer 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. To get the movement from someone besides clockworks.com, you may not know what one you will get. Please know that Clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will get

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.

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 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 you will see the numbers such as 451-050 94cm. These numbers let us know everything we need to know about the mechanical clock movement itself. This tells us if its weight driven, the plate size, and every other aspect of the movement.

When the numbers are matched, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of your existing clock components will fit just the same a it did.

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

Mechanical Clock Movement Issues

Mechanical Clock Movement Issues arise 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.

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.

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 Mechanical Movement Reasons

New Mechanical Movement Reasons to get the new one when we can just repair the old one? The reason is because it is still in production. Its still made in mass production in Germany, so this means its available for a lot less cost. Even the best repair job from the best repair professional, cannot make it as good as a new one.

New Mechanical Movement Reasons are because it can ship from USA the same day you order it. The time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement. All clock component parts such as weights will fit on to the new movement. The cost of a new movement is less and when it's installed it should last another 25-30 years without intense service. Over the years, if there is improvements that can be done on the movement, the factory updates them. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Conclusion

The new unit will cost less and ship now. It will be far better in every way than getting the old one restored. You will have a new movement in days instead of the used one back in months.

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.

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.

340 - 341 Hermle Clock Movement

The numbers on the back plate of the 340 - 341 Hermle Clock Movement is everything one needs to get a replacement. If the numbers match then the movement will match.

If the clock is a pendulum unit, be sure to select the proper CM length that matches the old unit. For example it may say 341-020 45cm on the Hermle Clock Movement. If your clock movement has an A at the end such as 341-020A, just ignore the A.

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.

What Clock Parts To Send

  Please send the movement only along with a note saying how much each weight weighs (if weight driven) and your contact information. Read More »

Please do not send keys, dial, hands, chime block, weights or pendulum as we have them here in the shop.

We are not responsible for any clock case damage that is shipped to us. Please do not send the clock case.

Cleaning for $150

  Mechanical clocks need cleanings periodically. When clock movements come out of the factory, the factory will say oil your new clock movement in 5 years, clean and oil it in 10 years. However not many go by this rule and if you have a clock from the 1800s or early 1900s, think of how it must need a cleaning at this point. By cleaning, this does not mean making it pretty and shiny although that will most likely happen also. Rather what is meant by cleaning is to remove all the old oil that has dried up in the pivot holes, so new oil can be applied. This is not usually visible but where the pivots posts spin inside the outer plates, if there is too much old dried up oil it will cause the clock to stop running. What we offer to you is a cleaning of the movement with the best equipment available, with the best solutions available, and then a inspection of the movement. If the movement does not need bushings or disassembly or parts, we will oil it and test run it. Cost is $150 plus shipping back to you if that is all that is needed.

Clock Movement Removal

  To remove your movement to send it in for Clock Repair, take off the hands by holding the minute hand and turning the minute hand nut to the left. Read More »

Once this nut is off, the minute hand will come off. To get the hour hand off, twist it and pull it toward you and it will come off as it is only a friction fit.

Remove any weights or pendulum that may be on the clock. Take the screws out that hold the movement in place. In grandfather clocks, these would be on the bottom of the movement going up to the outside arbors; for mantle and wall clocks they would be toward the front or back of the case.

The dial on most grandfather clocks are either attached to the case or to the movement itself. If it is attached to the movement, unclip it off of the back side of the front plate of the movement.


CLEANING AND OILING FOR ONLY $150

We have the best tooling, cleaning equipment, and cleaning solutions. There is no expense spared by us when it comes to having the best equipment. With this factor and 3 generations of clock repair expertise, you can rest assure your clock works will be in the best hands it can be in.

If this is all that is needed? that is all it will cost is the $150 plus the shipping back to you. The initial $150 is non refundable and is the fee for the cleaning, inspection, and oiling and testing only. We do need to be paid for our time on this even if the clock movement is deemed unrepairable for some reason.

HOW TO PACK IT UP

When packing up the movement, take special care to protect the hand shaft as this is hard to correct if it gets bent. This is the shaft that the hands go on to tell the time. You should pack the movement up well with newspaper and bubble wrap, or put the movement in a plastic bag and then use peanuts. If you use peanuts, please DO NOT let the movement get peanuts all up inside of it. Make sure you place the movement in the box with the hand shaft pointing up.

Once you have the movement packed really well in a box, pack it again in another box with more packing material. Double boxing provides extra cushion for the movement as it travels to minimize the possibility of damage.

After you have the movement alone packed up, please send it to: CLOCKWORKS 124 Goss Hill Rd, PO Box 339, Huntington MA 01050 USA. If you fill out the below form we will get notification about your clock coming and we will reply via email confirming your form submission.
