This is the classic design for German Torpedo timing and used in U-Boats and E-Boats in the North Atlantic during the first and second world wars. This WWII U-Boat watch is in near mint condition on the outside but does not function most likely just small loose gear on the inside. We have not tampered with the inside or disassembled it but believe the inside mirrors the great condition as well. The face is maker marked below center.
