A motion detection means 5 has a power generation detection circuit 51 for detecting the output voltage of a generating means 4, and a decision unit 52 for determining if the radio-controlled timepiece 1 is moving based on the output voltage from the power generation detection circuit 51. If when a standard time signal is to be received by means of a receiver 2 the not moving detection signal indicating that the radio-controlled timepiece 1 is not moving is output from the motion detection means 5, the reception operation is executed and the time displayed on the time display means 3 is adjusted. By receiving the standard time signal when the radio-controlled timepiece 1 is not moving, accurate time information can be received and the reliability of standard time signal reception can be improved because the reception success rate is also improved.
