How to Replace a Weight Driven Clock Movements

Replacing a Movement

Introduction:

    If your clock was made from around 1965 to the present day, there is hope to get a new movement to replace your old one. Replacing is better than repairing because the new movements are free from bushing wear and sometimes the maker of the movements improve them over time. To pay someone to overhaul a movement that is still made does not make sense because the cost would be about the same to get a brand new unit. Clockmakers often charge even more to overhaul a movement then what a new one will sell for. This is because of the time and effort involved with the overhaul.


Identifying the movement:


    First thing to do is to get all the information off of the back plate of the clock movement itself and write it down. Be sure to remove the weights and pendulum if the case is to be moved to get to the movement. Do not make the mistake of looking for the model number of the clock, this number is on the paperwork that comes with the clock and is not what is needed to replace the movement. As stated above, the numbers needed are on the back plate of the movement itself.


Is your movement made by Hermle?:


    Hermle makes movements for various cabinet makers and marks there name onto the movement, so you may have a Hermle movement even it has a different name on it. Some other names made by Hermle are Seth Thomas (the newer Seth), Tally Industries, Howard Miller, and others.

HOW TO ORDER HERMLE:

Hermle uses a 6 or 7 digit number code to designate whether it is spring, chain, or cable driven, the plate size, hammer arrangement, and the hand shaft length.

Back Plate Example:
77
Howard Miller
1161-853
94cm

    The above example shows the movement number being 1161-853. Hermle made this movement for Howard Miller and its pendulum length is 94cm from the suspension post down to the very bottom of the pendulum. To get a new replacement movement for this clock, the first set of numbers would be matched up with the below chart. In this case 1161 would be selected below and all the movements that start with 1161 will come up in a webpage for you to select from.

Seth Thomas clock owners:


    These movements have number on the back of them that look similar to Hermle numbers but they start with an A at the beginning. For example: A406-010 would be a Seth Thomas movement number. These movements are still made by Hermle and we have them in stock, just follow the link to the Seth Thomas page and get the Hermle replacement number.


Mason and Sullivan clock owners

   
These movements have number on the back of them that ends with an X. For example: 3318X would be a Mason & Sullivan movement number. These movements are still made by Hermle or Keininger and we have them in stock, just follow the link to the Mason & Sullivan page and get the Hermle or Keininger  replacement number.


Jauch clock owners

    Jauch movements are not made anymore. If you need a Jauch replacement there is still hope, we offer  Hermle units as Jauch Grandfather replacements.


If no luck yet:

    If your clock did not match up with any of the numbers above, then your clock could be made by Keininger or  Urgos. These  movement manufacturers are harder to get replacement for, but we do stock the most common models. You can check the Keininger, Urgos, or Jauch pages within this site for your movement, or Email Us the numbers and we will see if we have it. We do stock some units that are not listed, so again, when in doubt Email Us the information off of the back plate of the movement and we will check stock for you.
