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 restored 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. Get a new movement instead of a fixed up old one, get it in 3 days instead of 6 months. Save hundreds of dollars doing it also.
Hermle clock movement 130 - 131
Hermle clock movement 130 - 131 is a round unit with a 90mm plate size diameter. They all take a size 4 clock key (not included), they come oiled and ready to go. The most compact movement produced in the Hermle clock movement line. They fit into the tightest of spaces and come in either pendulum units or balance units.
130 - 131 balance wheel
If it is a balance unit there will be a big balance wheel in the center and top of the unit. A balance wheel is advantageous in that it never has to be put into beat. You can move it from here to there and it will work just as it did. It does not even have to be level and can be in a room that has vibrations or shaking, does not matter.
The 130 or 131 clock comes as the movement alone
Installation is easy and we are here to help if you need it. What is being offered on this page is the movement alone with no other components such as pendulums and gongs. The movements come with the hand nut and also the suspension spring and leader if it is a pendulum unit.
Hermle Clock Pendulum Measuring
If a Hermle clock doesn't keep proper time, the pendulum may be incorrect. To determine if this is the problem, measure all of the components of the pendulum. Hermle clock pendulum measuring is extremely important. Often enough the CM length stamped on the movement is not the actual pendulum length. Certainly, the CM stamp provides valuable information, however it does not state what the Hermle clock pendulum needs to be from tip to tip. This section describes what the CM stamp represents, as well as how it needs to be measured.
What the CM represents
To measure a Hermle clock pendulum, start at the very top of the movement. Continue all the way down to the bottom of the rating nut on the pendulum. The CM number will only be accurate to the pendulum length if the bob diameter is small. In other words, the larger, or the heavier, the bob is, the longer the pendulum needs to be despite the stamped length on the movement. If confused, please email Clockworks in order to determine the best pendulum length. Please provide the Hermle clock pendulum CM length stamped on the back plate of the movement. Also, include the width of the pendulum bob. The bob is the round disk at the bottom of the pendulum.
Hermle Clock Pendulum Measuring - Parts that are measured
The Hermle clock pendulum length (**cm) is the distance from the suspension post all the way down. Meaning to the bottom of the pendulum nut threads. This measurement includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring. This pendulum length will not always be the same as what is marked on the movement. Subsequently there are also other factors that play into this measurement. For instance, the pendulum bob diameter. The larger the pendulum bob diameter, the longer the pendulum length needs to be despite the CM length.
In conclusion, if the Hermle clock pendulum CM length on the old unit matches the CM length on the new unit it will keep proper time with the same pendulum. There are times when the old leader needs to be used on the new movement, but this is not common.
Mechanical Clock Movement Wear
Mechanical clock movement wears out 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 brass plates of the movement. So, when this happens, the clock movement will not run correctly. This is when the movement will need a cleaning at least, or be replaced. Of course, a brand new movement is always your best option.
What wear and where
Look at your old clock movement, and 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. However, once the movement starts having problems due to the oblong pivot holes, something will need to be done. The clock will never stay running otherwise.
New Clock Movement Benefits
New clock movement benefits far outweigh the benefits of an . 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 have fresh oil 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. So obviously this is a new clock movement benefit.
Every time the movement needs to have work done on it or needs bushings, it will last less and less time before it needs attention again. So another new clock movement benefit is that this would not happen. 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 clock 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 a new clock movement. 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 clock movement is a factory fresh restart. The clock will be like it was originally when you first made the purchase 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 clock movement 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 That Would Need a Repair or an Overhaul
If a unit is no longer in production and not available new, then a repair is most likely the only option. However we will try to convert it to a new clock movement 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 have us work on it.
Another movement to consider having restored instead of replacing it is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is due to the high price on the new clock movements which is over $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by Clockworks anyway. We can charge a much lower amount 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 new clock movements.
Clockworks = The best repair service
We would love to do the overhaul here at Clockworks 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 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 have lubrication 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 are sent via email) it's only a matter of removing the two screws from underneath. The new clock movement can then be put in by someone with experience in 10 or 15 minutes. A person with no experience will take longer, but the point is that it isn't hard to do. This is definitely a new clock movement benefit. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for clocks that were in a mass production this is not the situation. This relates more to a few individual clockmakers who's design of the case makes it more tricky to get the movement in or out.
Summary of New Clock Movement Benefits
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 produces clock movements but the use of aliases is quite prevalent. The movement could have a stamp with any name but really it will be made by Hermle. Some companies bought so many movements that they were able to get their 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 Aliases in Disguise
Seth Thomas and Mason and Sullivan had not only their name, but also their own internal numbering system. Their stamp and number was on the movement instead of the Hermle number. Since it is not a Hermle number, the number would need to have a conversion to the real number. Correspondingly, 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. Of course, you do not have to think and decide if a repair is better, the answer is a simple no. These companies went out of business a long ago and the life of the unit is over. Ordinarily, the lifetime is 25 - 30 years before it needs an overhaul or replacement. In fact, if ST or Mason Sullivan is on the movement that would indicate the clock is about 40 years old or more.
The other Hermle Clock Movement Aliases are easy
All in all, Hermle Clock Movement Aliases on other clocks use only their name, and not their 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. Additionally, the numbers will indicate what movement it is. If it is a Hermle movement there are 3 or 4 digits then a hyphen, and then 3 more digits. For example, 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.

About the 131-081 movement
The 131-081 Hermle Clock Movement runs 8 days on a single wind. It has two hammers towards the top with a included bell. The movement will strike out the top of the hour via the bell, and then once for the half hour. This brand new 131-081 is straight from the factory in Germany. The movement comes oiled and includes its improved balance for ease of fine timing. Replacing a movement is less costly than a overhaul. This high quality German movement comes oiled and includes its leader, suspension spring and hand nut. The clock will be problem free right away instead of months, last longer than a overhaul.
Ordering a Hermle Clock Movement
The numbers off of the back plate of the movement itself are needed when ordering a Hermle clock movement. The numbers are matched up so the new movement will be exactly the same as the old one. Replacing the movement is a fraction of the price of a repair. It is also the fastest way to get the clock up and running again.
Clock movement removal and installation
Removing and installing the clock movement requires the most basic tools. If you can change the spark plug on your lawn mower, this will be a breeze. All of the Hermle clock movements are in stock and ship immediately. We are full time clock makers and retailers. This means we can help you from start to finish. If you need assistance in picking out the correct Hermle clock movement, installation or troubleshooting, we can help. Please do not hesitate to ask.
Matching the CM when ordering
This note only applies if the current Hermle clock movement has a pendulum. Please match up the CM length from the back plate of the old unit to the new one. The options in the drop down menu ultimately indicate stock items that are available. However, if there is a CM number that is needed and is not listed, we can usually create it by changing some gears. If this is the situation please give us a call 800 381 7458. There is an extra fee for regearing the movement. Usually this is an additional fee of $30 to $40.
Replacing a movement is less costly than an overhaul. The movement will last another 25 years before needing any work. Since it is still in production, and offered at a very reasonable price, it makes sense to replace the movement. The clock will be problem free right away, instead of months. Plus it will inevitably last longer than an even the best overhaul. There is no way you can get better than brand new. So please make the wise decision of replacing whenever possible.
Hermle Clock Movement Directory Explanation
Above all, the Hermle clock movement directory is to get to the correct page that contains the proper clock movement. This is an important first step when ordering a new clock movement. Thus, Hermle mechanical movements have numbers on the back plate starting with the below few numbers. Then a dash (-) follows and then some more numbers. For example: 340-020 131-070 1161-853 351-020 and so forth. So, if the clock says something like 1161-053 drop the second half and click the 1161 button below. Then this will bring up the page where the 1161-053 is as well as the rest of the 1161 series.
Hermle Clock Movement Directory, Number starts with.....
If Not Listed
If the old Hermle clock movement is not found on these pages we may still have it as a conversion or we may be able to create it out of what exists. However, we need to know the movement number. So please email your movement number. Of course a picture of the back plate is also helpful. Moreover, if your movement numbers do not look like the Hermle movement numbers it may be made by someone else. Additionally, the mechanical movement identification page will assist you with determining who made the clock. In any event, this is for post WW2 modern mechanical clock movements made in Germany only.
