ELECTRONIC TIMEPIECE
First Claim
1. An electronic timepiece that includes a solar panel which receives light to generate electric power, is operated with the electric power supplied from a secondary battery charged with an electromotive voltage of the solar panel, and includes a normal mode in which time point display is performed on a display unit, and a power saving mode in which a state where light incident to the solar panel is not obtained is detected to stop time point display of the display unit, the electronic timepiece comprising:
- a control unit which avoids transition from the normal mode to the power saving mode, when a voltage of the secondary battery is equal to or more than a predetermined first voltage value.
