It is not uncommon to find clocks that are supposed to have Geneva Stops, with the stops removed, or partially removed.

The purpose of Geneva Stops is to keep the clock wound in the strongest most consistent part of the spring.

The stops consist of two wheels. The wheel on top has one spoke that is longer than the others. The wheel on the bottom has one valley between the teeth that is shorter than the rest.

When winding the clock, the winding action stops when the long tooth hits the short valley.

To set this, wind the clock full, then back off two turns. The stops are then set to stop there.

An interesting innovation. I'm not sure what real difference it made in the timekeeping, but I suppose it made good press.

This particular movement goes in a Seth Thomas Office No.1.

This is the case. The dial is an old replacement. I am going to put a good Seth Thomas replacement label on it.
