Hermle Clock Movement

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 get an overhaul, like you normally would with any clock, is found to be a much higher cost. This is for good reason as it can be a large task to restore it. But as you see, since it's a modern day unit (German Post War) it can be available new for a very good price. So what happens is you get a new movement instead of fixing the old one and you can get it in a few days instead of 6 months. You will save hundreds of dollars doing it also.

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. 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.

Hermle Clock Movement Identification

Most important is the identification of the Hermle clock movement and it requires locating the numbers on the back plate of the movement itself. This can be done by removing access panels, sticking a phone inside and taking a picture, or even a mirror. Use any possible means to get the number of the Hermle clock movement. This information is not in the manual that came with the clock or on the wood case. On the back plate of the Hermle clock movement there are numbers such as 451-050 94 cm. These numbers indicate everything there is to know about that particular mechanical Hermle clock movement.

Ordering the Hermle Clock Movement

With the numbers off of the back plate we can start ordering the Hermle clock movement. This stamp will be right in the brass, so it maybe tricky to get to. Of course, the easiest way is to just use a cell phone and take a picture of the back. If there are side access panels on the clock case it makes it easy. If you do not have a cell phone you can do the mirror and flashlight trick. Either way after you get the numbers off of it, we can narrow down the Hermle Clock Movement to order.

Why match the numbers

With the numbers off of the back plate of the Hermle Clock Movement, we can now match it. Moreover, the movement numbers mean everything for the replacement unit. It tells us all about every aspect of the clock movement. If you match the numbers with the list, it will be the same movement. So, if the numbers from the movement do not match correctly, it will not fit right in the case.

Matching the numbers

All in all, the first thing to do when ordering a Hermle clock movement is to match the movements number's prefix. The numbers prefix is the first set of numbers in the set. Such as 1161-853 114cm, the prefix would be 1161. Click the list of movements prefix 1161 to see all the movements in that 1161 series. You would then see movements such as 1161-053 or 1161-853 Once you have the prefix then look for the last 3 numbers of the movement. Then, from the drop down menu the correct cm length can be chosen. That is all the steps to order a Hermle clock movement.

Hermle Mechanical Clock Movement Availability

Hermle Mechanical Clock Movement Availability is excellent. We stock all Hermle Clock Movements, with very few exceptions. Some special CM lengths may be a special order. If it's not on the charts we may still have it, just contact us. You can call or email a picture to us. If a CM option is not in the list, we can still make it up special for you.

Who is Hermle?

Hermle is one of the largest movement producers in the world today. Not only do they have the most movements being made, but they also have the best part availability. This is good for when you need a component such as a pendulum or a dial, or a complete clock kit. A Hermle Clock Movement generally lasts 25 to as much as 40 years. We usually get calls to replace units that were built in the early 80's or late 70's.

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 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 or be replaced. Of course, a brand new movement is always your best option.

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. 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 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 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.

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.

Hermle Clock Movement Directory Explanation

Above all, a 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.

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.

Hermle Movement Date Codes

Hermle Movement Date Codes

Date Code Explanation

Hermle movement date codes are explained in this section. This is to know when the movement was made and decide if the clock has lived its life and is time for a new one. After finding the Hermle movement date code, it can be figured out how old the clock movement is. If the clock is over 20 years old it is time to replace it. If the clock is under 20 years old is the only time to consider fixing the movement instead.

Hermle date code change

Prior to using Hermle movement date codes, early movements before the year 1987 have just the stamp of the year on the back of the clock movement, 81 just means 1981. From 1987 on they used letter codes instead of numbers to represent the year made. Such as the year 1988 is only marked with the letter A instead, and 1989 is the letter B.

Letter Code Definitions for

This section explains the letters on the Hermle movement date code that sometimes come after the movement numbers on a Hermle clock movement. These letters often can be ignored when replacing a movement with Clockworks. The Hermle movement date code letters on the new movement may or may not be the same on the new one but this is not a concern. The features of the movement will be the same, such as if there was a second bit before and the movement number did not have an S, but the new one does have an S.
