Abstract
Abstract An electronic alarm wrist watch comprises a piezoelectric oscillator which vibrates the watch dial, crystal, or parts of the bezel such as the crystal mounting ring to produce an audible sound at predetermined times. The piezoelectric oscillator is energized by a low or high voltage power oscillator.
