This 1940’s vintage TUDOR (by ROLEX) is a WW2 Royal Canadian Navy Reserve having military markings on the case back. The steel TUDOR case has the correct OYSTER PATENT winding crown. The ORIGINAL dial retains the original raised markers and sword hands along with all the original lume. This is a smaller sized military watch measuring 28.5mm., with the steel case being very clean for its age. It is uncommon to find these WW2 vintage watches with their military markings.
