Hermle Clock Movement Aliases

Hermle Clock Movement Aliases

Hermle produces clock movements but the use of aliases is quite prevalent. The movement could have a stamp with any name but really it will be made by Hermle.

Some companies bought so many movements that they were able to get their 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 Aliases in Disguise

Seth Thomas and Mason and Sullivan had not only their name, but also their own internal numbering system.

Their stamp and number was on the movement instead of the Hermle number. Since it is not a Hermle number, the number would need to have a conversion to the real number. Correspondingly, 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.

Best to replace the movement

It is best to replace the clock movement if either of these names are on the movement automatically. Of course, do not have to think and decide if a repair is better, the answer is a simple no. These companies went out of business a long ago and the life of the unit is over.

Ordinarily, the lifetime is 25 - 30 years before it needs an overhaul or replacement. In fact, if ST or Mason Sullivan is on the movement that would indicate the clock is about 40 years old or more.

The other Hermle Clock Movement Aliases are easy

All in all, Hermle Clock Movement Aliases on other clocks use only their name, and not their own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin just look at the number and forget the name.

Additionally, the numbers will indicate what movement it is. If it is a Hermle movement there are 3 or 4 digits then a hyphen, and then 3 more digits. For example, 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.
