Abstract: An electronic timepiece includes a solar power source, a voltage stabilizer circuit that generates a constant voltage by using power supplied from the solar power source, and a control circuit that clocks the time by driving a rotating body at first hand operation speed and at second hand operation speed which is faster than the first hand operation speed. The control circuit selects a voltage of the solar power source so as to drive the rotating body in a case of the first hand operation speed, and selects at least any one voltage of the constant voltage and the voltage of the solar power source so as to drive the rotating body in a case of the second hand operation speed.

Abstract: To receive data normally in communication by an optical signal by an electronic device which transmits data even when a transmission frequency differs. An electronic device transmits a transmission-frequency measurement signal for measuring a transmission frequency of data and transmits the data by using a light source which transmits an optical signal. An electronic timepiece specifies the transmission frequency of data based on the transmission-frequency measurement signal received by a solar battery which receives the optical signal and receiving the data by the solar battery based on the specified transmission frequency.

Abstract: An electronic device includes at least an acquisition unit, an input unit, a time correction amount calculation unit, and a transmitting unit. A timepiece includes at least a receiving unit, a power storage unit, a drive unit, and a control unit. The input unit receives an input of the time displayed by the display unit of the timepiece. The time correction amount calculation unit calculates a time correction amount for correcting the time of the timepiece from a difference between the time, the input of which is received by the input unit and the current time acquired by the acquisition unit. The transmitting unit transmits the time correction amount to the timepiece by using light. The receiving unit receives the time correction amount. The power storage unit stores electricity by using power converted from the light. The drive unit drives the indicating hand. The control unit corrects the time displayed by the indicating hand, based on the time correction amount received, by the receiving unit . The control unit controls a power storage period in the power storage unit and a receiving period in the receiving unit so as to receive the time correction amount in the receiving period.
