MCM Jean Perret Swiss Made Peek-a-Boo Watch.

The markings include Plaque 10 microns, Jean Perret, Geneve, Swiss Made. Bracelet watch with hidden face. It appears to be in great shape, but is not working. I think it’s a wind up watch, but it’s not winding. Domed Crystal in great shape. Gold plated with enamel. It’s really a fun piece.
