A radio-controlled timepiece receives a standard time signal containing a time code and adjusts internal time data. The radio-controlled timepiece includes a reception unit that receives the standard time signal, and a control unit that controls the reception unit. The reception unit has an amplifier circuit that amplifies a reception signal of the standard time signal, and an analog/digital conversion circuit that digitizes the amplified reception signal and acquires a time code. The control unit sets the reception mode of the reception unit to a normal reception mode or to a high sensitivity reception mode that improves reception performance compared with the normal reception mode, sets the reception mode to the high sensitivity reception mode for a specific period that is set based on the time code of the standard time signal after establishing at least second synchronization with the time code of the standard time signal, and otherwise sets the reception mode to the normal reception mode. |
