A New clock movement will be the same movement you have now but brand new. It is not a cheap unit as a substitute, it is the same movement that are still being made.

Although Mason and Sullivan is out of business, the movements were not their own. They had them made by German manufacturers that are still in business and making the same movements.

A new movement will last longer than any repair is able to last, factory lubricated and improved upon, less money than a repair, and comes with a warranty.

On the back plate of the Mason and Sullivan clock movement itself, usually on the low right, you will see some markings with an X at the end of the number. This is if your clock movement has the Mason and Sullivan number system only.

Even though you purchased your clock from Mason and Sullivan, it does not necessarily mean that the movement will be stamped with the Mason and Sullivan numbering system. If you do not have an X in the number, then it is most likely a Hermle movement and you would need to go to that webpage.

The numbers on the brass back plate of the Mason and Sullivan clock movement is where we need to start with the identification, so we can determine the proper replacement.

The numbers and or letters will tell us everything we need to know.

With these numbers we can tell the strike hammer locations, the movement plate size, the hand shaft length and everything else.

So if you have an X in the number that is stamped on the back plate of the clock movement, it’s time to look for this number in the chart located below.

The movement that will be sent to you will have a different number, but it will be the same movement as they are still in production.

The new movement comes with the chains or cables and pulleys if it is weight driven, and they all come with the suspension spring and the clock hand nut as well.
