This 34.5mm. OMEGA Seamaster DeVille from the mid-60’s is a similar watch we provided to Jon Hamm on Man Men; only with this version having a silver dial instead of black. The quadrant dial having cool arrow steel markers at 12, 6 & 9 is all original and pristine including the hands. The bubble-date crystal and crown are also correct to the watch. The rotor winding OMEGA movement is accurate. This all correct Seamaster DeVille is one of the hottest watches available in the affordable vintage watch market at this time. Get one while its inexpensive.
