发明名称 Electronic timepiece
摘要 An electronic timepiece, comprises a timing section to perform timing of time based on an oscillation signal; an electric wave receiving section to receive an electric wave; a voltage detecting section to detect a power source voltage supplied from a power source section; and a stop control section to 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 then to stop the timing operation of the timing section when a warning period for urging a user to perform the power generation by the power generating section elapsed in a state where the power source voltage is lower than the first level range without changing to a lower level than a second level range lower than the first level range.
