Buzz Rickson offers this season a faithful reproduction of an original watch used by the US Navy during the Second World War. The USN BU Ships Canteen Diver Watch was created for US submarine demolition teams. The watch features the “Canteen” screw down water resistant crown. This was applied as a cover for the crown and it was designed to protect it from taking hits and to prevent water from getting into the watch. It is made of stainless steel with marking of U.S.N BU Ships at the back case.
