An attractive, sought after Certina diver. This 37mm vintage watch has had rough jobs in its more than 50 years and is not mint. It is a good, honest toolwatch though, retaining it’s original signed crown. It has red detailing on the dial consisting of hour sub-numbers from 13 to 24 and thin crosshairs. The rectangular hour markers (square at 12, 6 and 9) are not luminous, but the hands and bezel triangle light up under ultraviolet light. The lume on the hands have a small hole. The resin filled bezel is very nice, and because this watch dates from ca 1968, it rotates both ways without clicks. The automatic 25-651 movement has been fully serviced, and the serial number is 6949949.
