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 (23, 24) to receive an electric wave including a time code; a power source section to supply electric power to each of the sections; 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 stop the timing operation of the timing section; a first start control section to reopen the timing operation of the timing section when the power generation detecting section detects power generation of a predetermined quantity or more after stopping of the timing section by the stop control section, and a second start control section to make the time display section perform a normal time display operation when the power source voltage becomes higher than a first level range after the stopping of the timing section by the stop control section, characterized in that the stop control section is configured 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 the first level range, and is further configured 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, and in that the second start control section is configured to make the electric wave receiving section execute reception of the electric wave when the power source voltage becomes higher than the first level range after the stopping of the timing section by the stop control section. 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 (23, 24) to receive an electric wave including a time code; a power source section to supply electric power to each of the sections; 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 stop the timing operation of the timing section; a first start control section to reopen the timing operation of the timing section when the power generation detecting section detects power generation of a predetermined quantity or more after stopping of the timing section by the stop control section, and a second start control section to make the time display section perform a normal time display operation when the power source voltage becomes higher than a first level range after the stopping of the timing section by the stop control section, characterized in that the stop control section is configured 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 the first level range, and is further configured 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, 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 the first level range, and is further configured 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, and in that the second start control section is configured to make the electric wave receiving section execute reception of the electric wave when the power source voltage becomes higher than the first level range after the stopping of the timing section by the stop control section.
