Abstract
A radio-controlled timepiece includes: a radio wave reception unit that receives satellite waves and extracts an incoming code sequence encoded in the received satellite waves; a counter unit that counts a date/time of the radio-controlled timepiece; and a processor that: generates an expected code sequence containing at least a portion of a preamble code and a code generated on the basis of the date/time counted by the counter unit that are expected to be part of the incoming code sequence that is extracted, detects a match between the expected code sequence that has been generated and the incoming code sequence by sequentially comparing the expected code sequence with the incoming code sequence, and acquires a present date/time, as indicated by the satellite waves, in accordance with a detection timing of the match, as measured by the data/time counted by the counter unit.
