A radio-controlled timepiece, including: a radio wave reception unit that receives satellite waves and extracts an incoming code sequence formatted in a prescribed format from the received satellite waves; and a processor that generates in advance an expected code sequence that is expected to be part of the incoming code sequence and detects a matching code sequence segment, within the incoming code sequence, that has a degree of match with the expected code sequence that satisfies a prescribed matching condition, the processor determining a present date/time, as indicated by the satellite waves, in accordance with a timing at which the detected matching code sequence segment occurs within the incoming code sequence as measured by time kept by the timepiece.
