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.
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.
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. 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 flash light trick. Either way after you get the numbers off of it, we can narrow down the Hermle Clock Movement to order.
Matching the numbers
With the numbers off of the back plate of the Hermle Clock Movement, we can now match it. 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.
The first thing to do 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.
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.
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.
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.
