The invention seeks to provide a radio-controlled timepiece that is easy to operate, affords improved manufacturability and productivity, and affords cost reduction. The user pulls the crown 300 out when the second hand 240 is positioned at 0:00 (12:00), changes the indicated time within +/-30 seconds of the current time confirmed from a time announcement, for example, and then pushes the crown 300 in. At this operation the count of the seconds value of the internal counter 433 is set to 00 seconds. The count (00 seconds) of the seconds value and the seconds value of time data derived from a longwave standard time signal received by the reception means 420 are compared, and the time difference therebetween is determined. If the time difference is within +30 seconds, the time is determined to be advanced by the difference, and if within -30 seconds is determined to be delayed by the difference. The received time data is written to the internal counter 433. The hands are then moved according to the delay or advance of this time difference to adjust the time. |
