Radio-controlled watch

摘要

When a voltage generated by an electrical generator means becomes below a certain value, a detection signal from a voltage detection means opens a switching means. The supply of electrical power from an electrical storage means to a radio-controlled timepiece circuit is stopped. When the voltage generated by the generator means regains the given value, the detection signal from the voltage detection means closes the switching means, supplying electric power to a radio-controlled timepiece circuit. At the same time, a control signal from the voltage detection means activates a radio receiver circuit. Thus, a timepiece body circuit is synchronized by radio control technology. Precise time is displayed by a display means .
