HOW TO ORDER: 

    Find the model number on the back of the clock movement that match the numbers on this list. Usually there is three or four numbers followed with a dash (-) and then another set of three or four numbers. Then find the centimeter length, just below the model number, it looks something like this (66CM). This centimeter length represents the length of the pendulum measured from the suspension post down to the very bottom of the threads on the rating nut. (If the clock has one). Match these up to the list and you have a brand new movement that will replace your broken one. 

Movements may vary from the picture
The matching of the movement number is what makes the difference,
if the old movement number matches on the list, then you will get that exact same movement.

NOTE:

    Many of the Hermle movements have been improved upon by the factory over time. Some 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.
