The watch has a 17-jewel Swiss hand-winding movement which is working nicely. There are two empty retaining screw holes within the movement, these screws are not required as the movement is held in place by the case.

The lens is in lovely condition.
The signed dial is in its original finish with original hands and a subsidiary seconds dial.
