摘要： Provided is a radio-controlled wristwatch capable of determining whether or not the illuminance of light irradiating a solar cell is high on the basis of a plurality of different criteria without directly measuring an output voltage value or an output current value of the solar cell. The radio-controlled wristwatch includes: a solar cell; a control circuit which stops operation under a predetermined condition; and an illuminance detection circuit which outputs a signal indicating whether or not illuminance of light irradiating the solar cell is higher than a given threshold value. The radio-controlled wristwatch switches the given threshold value between a first illuminance threshold value and a second illuminance threshold value that is larger than the first illuminance threshold value, starts the control circuit in a stop state when a signal indicating that the illuminance is higher than the first illuminance threshold value is output, receives a satellite signal containing time information from a satellite when a signal indicating that the illuminance is higher than the second illuminance threshold value is output, and displays time corresponding to the time information contained in the received satellite signal.

摘要： Whether a bright state or a dark state is established is determined each time a motor is driven one step, based on a presence or absence of a passing of light through a detection hole (305a) disposed in a detection wheel (305) that rotates associated with rotations of a hand wheel coupled with the motor. A switching position X is identified at which the dark state is switched to the bright state when the dark state is determined and thereafter the bright state is determined. A position one step after the identified switching position X is set to be a reference position X+1 of the hand wheel. The reference positions X+1 and X-1 can thereby be set after a driving mechanism is assembled.
