A timepiece for receiving a broadcast time signal containing correct time data for correcting a time error. A control circuit controls reception of the broadcast time signal depending on a time error. A current time is counted, and a time error dependent on the correct time data and the current time is determined for adjusting the current time. The reception of the broadcast time signal is controlled at intervals or times which are dependent on the time error obtained at a preceding adjustment operation so that the reception operation is executed only when necessary, thereby reducing power consumption. |
