Radio-controlled timepiece, system, and method for controlling radio-controlled timepiece

A system comprising:

• a receiver configured to receive a satellite radio wave including first time information;
• a short-range receiver configured to receive a radio wave including second time information transmitted from a mobile device;
• an operating device configured to accept an instruction operation;
• a reception controller configured to selectively execute a first reception processing of acquiring the first time information by operating the receiver at a preset time and a 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;
• 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;
• and
• the mobile device, wherein
• the mobile device includes a second operating device,
• the mobile device is set, by an operation of the second operating device, to a communication prohibition mode in which a communication with another device is prohibited,
• the mobile device starts a function of communicating with the radio-controlled timepiece when the communication prohibition mode is canceled by the operation of the second operating device, and
• the mobile device automatically activates an application for communicating with the radio-controlled timepiece when the communication prohibition mode is canceled by the operation of the second operating device.

A method for controlling a radio-controlled timepiece, the radio-controlled timepiece including

• a battery configured to store power,
• 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, and
• an operating device configured to accept an instruction operation, the method comprising:
• executing a first reception processing by the receiver at a preset time;
• executing a second reception processing by the short-range receiver in response to the instruction operation from the operating device;
• correcting 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;
• and
• setting an automatic reception prohibition mode by an operation of the operating device and in which the first reception processing is not executed at the preset time,
• wherein the instruction operation from the operating device includes an operation of canceling the automatic reception prohibition mode, and
• when the automatic reception prohibition mode is canceled by the operation of the operating device and an amount of power storage of the battery is equal to or higher than a predetermined value, the reception controller is configured to execute the second reception processing.
