In the prior art, a radio-calibrated timepiece equipped with various functions including time adjustment depending on a radio signal has a shortcoming if it has non-receiving mode when a secondary battery is used for the power source. Specifically, it is not possible to receive a radio signal, depending on mode, though normal conditions have been restored after a stop of operation due to a drop of supply voltage, and thus the useful radio time adjustment is not effective. Therefore, there is provided a timepiece designed to automatically start receiving a radio signal carrying a time code as soon as it resumes operating after the failure of the power source. <IMAGE> |
