Abstract

Disclosed is a radio-controlled timepiece. The radio-controlled timepiece includes an oscillating unit, a display unit, a display driving unit, an error storage unit, a radio wave receiving unit, and a frequency setting unit. The display driving unit drives the display unit with a driving signal of a predetermined driving waveform frequency generated by the clock signal output by the oscillating unit. The error storage unit stores error data of an oscillating frequency. The radio wave receiving unit tunes to a receiving frequency of a radio wave including time information, and receives the radio wave. The frequency setting unit sets the driving waveform frequency based on the error data so that the receiving frequency does not overlap with a higher order harmonic wave of the driving waveform frequency during a period that the radio wave is received.
