Abstract:
1. A timepiece, comprising: a reception unit that receives a signal; a timekeeping unit that keeps internal time; a solar cell; a voltage detection circuit that detects an illuminance of light incident to the solar cell; and a reception control unit that, every day when the time kept by the timekeeping unit reaches a predetermined time, determines whether a current date is a reception day or a no-reception day, and if the current date is a reception day then the reception control unit selectively executes an illuminance-based reception process that operates the reception unit when the illuminance detected by the voltage detection circuit equals or exceeds a set threshold, and if the current date is a no-reception day then the reception control unit does not execute the illuminance-based reception process.
