Patent ID: 8213266

Claim:
An electronic timepiece, comprising: a timing section to perform timing of time based on an oscillation signal; a time display section to display the time based on the timing of the timing section; an electric wave receiving section to receive an electric wave including a time code; a power source section to supply electric power; a power generating section to accumulate electric power in the power source section by performing power generation; a voltage detecting section to detect a power source voltage supplied from the power source section; a power generation detecting section to detect the power generation of the power generating section; a stop control section to: (i) stop a receiving function of the electric wave receiving section and continue a timing operation of the timing section when the voltage detecting section detects that the power source voltage becomes lower than a first level range, and (ii) stop the timing operation of the timing section when a warning period in which a user is urged to perform the power generation by the power generating section has elapsed in a state in which the power source voltage is lower than the first level range without changing to a level lower than a second level range, the second level range being lower than the first level range; a first start control section to reopen the timing operation of the timing section when the power generation detecting section detects that power generation is at least a predetermined quantity after stopping of the timing section by the stop control section; and a second start control section to make the electric wave receiving section execute reception of the electric wave and make the time display section perform a normal time display operation when the power source voltage becomes higher than the first level range after the stopping of the timing section by the stop control section.
