An Orion Seal with manual mechanical movement. Date display and rotating bezel that can be turned in two directions. 70s. The watch is in a good used condition for a watch of 50 odd years old . Wear and tear commensurate with age and use, but winds and ticks away and appears to be fully functioning. Despite the diver on the back, this one has probably taken its last shower and should be tucked away for occasional use and display before jumping into the pool with it. Measures 40mm without crown. Please check the pictures and any questions just ask
