Piece measures 74.5mm when opened in width and 49.5mm x 35mm when closed. Not currently working and requiring repair. I have not taken apart to check movement but the balance is at least broken as it does not tick, no audible sound of balance swinging. The piece is currently fully wound. There is wear to the plating and the open/close mechanism also seems to have issues as this is stiff and sticks and not functioning correctly. Selling for parts or restoration.
