Abstract
In an alarm electronic timepiece having a reference time generator, a normal hand stepping pulse generator for driving a stepping motor, an alarm coincidence circuit and an electric buzzer, it includes an alarm hand stepping pulse generator which produces an alarm hand stepping pulse to drive the stepping motor instead of the normal hand stepping pulse from the normal hand stepping pulse generator, in an alarm sound generating state. The alarm hand stepping pulse produces at the lowest alarm sound pressure of the electronic buzzer, whereby a highly reliable and acoustically excellent alarm electronic timepiece is provided.
