How to identify a Hermle movement

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.

With age, the mechanical clock movements 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 hundreds, if not over, a thousand dollars and in some cases it can take weeks or months to complete it.

A new mechanical clock movement can ship from USA the same day you order it, so 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, so all clock components will fit on to the new movement. The cost of a new movement is usually the same if not less than a cleaning on the old unit, and when it's installed it should last another 25-30 years without thinking about replacing or servicing it again. Some new units have bronzed bushings in key wear areas to increase the life of the movement, and on the non-pendulum units the balance has been improved upon for longer life and ease of timing. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.
