摘要:
A radio-controlled timepiece includes a receiver configured to receive satellite radio waves including first time information, a short-range receiver configured to receive radio waves including second time information transmitted from a mobile device, an operating device configured to accept instruction operation, a reception controller configured to selectively execute first reception processing of acquiring the first time information by operating the receiver at a preset time and second reception processing of acquiring the second time information by operating the short-range radio receiver in response to the instruction operation from the operating device, and a time correction controller configured to correct a display time based on the first time information acquired in the first reception processing or the second time information acquired in the second reception processing.
