Abstract
A diver's watch having a watch case and a register ring which is rotatably mounted on the watch case to set a diving time. The register ring has a plurality of notches on the underside thereof and is urged by clicks made of spring plate and held by a holding ring secured to the watch case. A plurality of lock notches are formed on the outer periphery of the watch case. A lock pin is projected from the inside of the register ring and engaged with one of the lock notches, so that the register ring is locked to the watch case. When the register ring is depressed against the clicks, the lock pin disengages from the lock notch, so that the register ring can be rotated.
