Abstract
PURPOSE: To easily control the time of alarm sounding through a relatively simple construction, by providing a means for generating a reference pulse at a prescribed period and a means which is controlled depending on the state of an alarm crown.
CONSTITUTION: A wheel train drive type alarm switching mechanism M including an alarm wheel etc., a means 40 for generating a reference pulse signal at a prescribed period, and a circuit 43, 45 which stores the output signal of the mechanism M and receives the reference pulse signal supplied after the storage to control the time of alarm sounding are provided. An alarm crown 16 for driving the alarm wheel from the outside of a timepiece, and a switch mechanism S2 interlocked with the crown 16 are provided further. It is detected by the switch mechanism S2 that the crown 16 is set in a state for driving the alarm wheel. Control is performed at 31W33 to immediately sound an alarm without wating for the reference pulse signal when the output signal of the mechanism M is supplied at said detection.
