Please view these information tabs to determine the Identification of the Mechanical Clock Movement .
Finding the mechanical clock movement
Finding the mechanical clock movement to replace the old one is done with the following steps. The first step is to identify the country of origin of the mechanical clock movement. If the mechanical movement is stamped made in Germany or West Germany, then the availability of this is much higher and we can help with a new one.
If the clock is made in any other country such as USA, France, Korea, or China, then you need to contact us via email with pictures of the movement to [email protected] so we can try to help with either a repair or replacement, as these will typically be antique units. If you do have a German unit you would need the numbers off of the back plate of the movement itself, right off the brass back plate.
The numbers on the back plate of the brass movement tells us everything about the Mechanical Clock Movement. Although it may not say the manufacturer on the movement, the numbers will give us this information. The movement numbers usually tells us the way the clock chimes, where the chime hammers are located, if it's weight or spring driven and much more. So with the movement numbers we can have a replacement clock movement that is not a knock off version, it is the same movement that was made the same as the old one. Usually all the old parts such as the clock weights, pendulum and hands will all work with the new movement, as the new one will be the exact same thing as you're old movement.
Using the examples below, narrow down the manufacturer of you're movement and go to that clockworks.com web page to order. When you get to the proper movement on the website, do not worry if the picture is not exactly the same as what you have. The matching of the mechanical clock movements number is what makes the difference. If the old movement number matches the one on the list, then you will get that same movement.
- Less cost than a cleaning
- Last 25-30 years
- Easy to install, we can help/li>
- Ships same day as order
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.
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.
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 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 or the numbers to [email protected] If a CM option is not listed, 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.
Why get the new one?
Replacing these units rather than getting them cleaned and oiled is usually the smart way to go. It has been factory improved, brand new, factory lubricated, easy to install. The new one would cost the fraction of the price of an overhaul on the old unit. Keep in mind however, that there are different grades of the same movement number. Some are cheaper, but they contain plastic parts. The Hermle units that we offer here at Clockworks are the best grade available.
What numbers to getThe movement number has three or four numbers, then a dash, and some more numbers, then a CM length underneath it if there is a pendulum. They are all consistent as they always have the numbers, then a dash, then more numbers. Basically if there is a dash in the movement number, and it's all numbers in the beginning with no letters like "A", it's a Hermle unit for sure. If there is an A before the number then it can still be a Hermle, but with the Seth Thomas name and numbering system.
What the numbers mean
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 the clock is weight driven or spring driven, if it has a pendulum, the size of the movement and the length of the hand shaft and much more. To match up the numbers to the new movement numbers is to get the exact same movement you have now but brand new. Since the new movement will be the exact same and not some knock off imitation, all of your existing clock components will usually fit just the same as the old unit.

Hermle is one of the largest Mechanical Clock Movement producers in the world today. Not only do they have the most Mechanical Clock Movements being made, but they also have the best part availability when you need a component such as a pendulum or a dial, or a complete clock kit.
A Hermle Mechanical 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.
If you look at the back plate of the movement, you will see a couple of numbers above all the other numbers. You will see a number such as a 77 or an 83 or so on. This is the date the Mechanical Clock Movement was built.
Replacing these units rather than getting them cleaned and oiled is usually the smart way to go as it has been factory improved, brand new, factory lubricated, easy to install, and it will cost less than a cleaning. Keep in mind however, that there are different grades of the same movement number. Some are cheaper, but they contain plastic parts.
The Hermle Mechanical Clock Movements that we offer here at Clockworks are the best grade available with no plastic components for a very reasonable price. The movement number has three or four numbers, then a dash, and some more numbers, then a CM length underneath it if there is a pendulum.
They are all consistent as they always have the numbers, then a dash, then more numbers. Basically if there is a dash in the movement number, and it's all numbers in the beginning with no letters like "A", it's a Hermle unit for sure. If there is an A before the number then it can still be a Hermle, but with the Seth Thomas name and numbering system.
Kieninger Movement Availability
Kieninger mechanical clock movements are usually available with no problems. The 5 tube mechanical clock movements are no longer made but the rest are usually in stock.
Kieninger clock movements are sometimes a bit tricky to tell what the actual number is. They give part of the numbers but then it is up to you to use the chart to figure out the rest of it. This would depend on if the movement is chain driven or cable, the pendulum length, and so on.
Urgos Movement Availability
If the clock movement is spring driven, then email us the movement numbers and we will see what we can do with a Hermle mechanical clock movement that is close to what you have.
Seth Thomas Availability
Back in the old days, there was a company who sold many mechanical clock movements out of Plymouth Hollow, CT and so they changed the name of the town to Thomaston, CT after the company.
So now if the clock is very old and made in the USA with an ST marking in a diamond shape, then that is an original Seth Thomas and there would be no replacement movement for this. Your only option is to get this repaired.
If the Seth Thomas mechanical clock movement says made in Germany, then use our list to see what the real clock movement numbers are so you can price it out and order it. The thing is, the company did not produce any modern clock movements, however their name is marked on them as their own. So if the clock says Seth Thomas but it was produced after around 1960, then it is made by someone else with the Seth Thomas name for Mechanical Clock Movement Identification.
So if someone were to purchase a Seth Thomas clock as an original Seth Thomas, and it ends up being produced by a different company, is it really a Seth Thomas clock? Yes and no. It is a true Seth Thomas as it did come from who ever owned the rights to that name at that time. But, the movement itself may not be actually produced by the Seth Thomas clock factory in Connecticut, as one would like to think of the ST name.
Jauch Movement Availability
A Jauch can be identified by a few distinguishing characteristics. Fist, the Mechanical Clock Movement will say made in Germany, with no other information, or very little information. Second, it may have numbers similar to the ones listed, but it's chain driven with a wood stick pendulum. These are all indicators of a Jauch movement which we can usually provide a retrofit for.
Mason and Sullivan Availability
You would need to go to the Mason and Sullivan page and look up the M+S Mechanical Clock Movement number in order to begin the Mechanical Clock Movement Identification process. This chart will allow you to find the real Mechanical Clock Movement number, from the true manufacturer, and be able to order it.
Hermle Movement Date Codes
Date Code Explanations
Hermle clock movement date codes are explained in this section. This is so you know when the movement was made and decide if the clock has lifed its life and its time for a new one. After figuring out the date code, figure out how old it is so you can justify the purchase of a new one with ease. If your clock is over 20 years old, replace it. If the clock is under 20 years old, consider fixing it instead.
Early movements prior to 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 1987 is only marked with the letter A instead, and 1988 is the letter B.
Letter Code Definitions
This section explains the letters that sometimes come after the movement numbers on a Hermle clock movement.
These letters often can be ignored in replacing a movement with us, we offer movements by the features instead. The letters on the new movement may or may not be the same on the new one, but you need not concern yourself with this. The features of the movement would be the same, such as if you had a second bit before and the movement number did not have an S, but the new one does have an S.
