The movement is currently running, although the chronograph may be a bit sticky to start. Once it’s running, the split activates and both hands reset as expected. However, the repeating function is not currently operating, but the train engages and the rack can be seen moving under the dial. The dial is in good condition with slight wear to the outer track between 30 and 35 minutes. The case is in good condition with tarnishing throughout.

Encased in silver and of large size, the watch has a particularly satisfying weight to it. The details of the watch are specified on the Breguet certificate.
