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 for controlling the output of an alarm switching mechanism.
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 at 42 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. A prescribed operation of the crown 16 is detected by the switch mechanism S2. Control is performed at 35 to inhibit the storage of the output signal of the switching mechanism M by the circuit 42 or erase an already stored content depending on the result of the detection of the operation of the crown 16.
