A method for calibrating a light smart watch includes: providing an FPC soft board under a dial, a size of the FPC soft board matching a size of the dial, the FPC soft board is divided into a plurality of partitions, each partition is insulated from other partitions, and each of watch hands and each partition form a capacitor in turn when the watch hands run; detecting a capacitance change amount of each partition, determining positions of partitions where the watch hands are currently located, and determining a current time indicated by the watch hands, according to the positions of partitions where the watch hands are currently located; comparing the current time indicated by the watch hands with a current time of a mobile terminal to determine a time error; and adjusting the watch hands, according to the time error to run in sync with the time of the mobile terminal.

An electronic watch includes a GPS receiver, a first time correction unit configured to correct time using the time information received by the GPS receiver, a beacon receiver configured to receive a beacon signal containing beacon identification information transmitted from a beacon installed indoors, a first storage unit configured to store beacon identification information and time difference information corresponding to the beacon identification information, a second time correction unit configured to correct a time difference using the beacon signal received by the beacon receiver and the time difference information stored in the first storage unit, and a button configured to accept a reception instruction of the beacon signal, which is operated by an operator. The beacon receiver is configured to receive a beacon signal when the button accepts the reception instruction.

A wireless communication device includes a communicator and a processor. The communicator wirelessly communicates with another wireless communication device. The processor controls the communicator to send an advertisement to the another wireless communication device at a predetermined time interval. The advertisement includes identification information identifying the wireless communication device. The processor changes sending settings on the basis of elapsed time from a start of the sending of the identification information.

A timepiece includes a clock circuit, a signal receiver configured to receive signals including time information, a processor configured to control a changing operation of changing a current time measured by the clock circuit based on the time information obtained from the signal receiver and controls a presenting operation of whether or not the changing operation is successful. The processor controls the changing operation based on a first flag indicating whether or not the signal receiver successfully receives the time information. The processor controls the presenting operation based on a second flag indicating whether or not the changing operation is successful within a predetermined period of time.

A method and device for determining a constant parameter of an inhibition value for adjusting the device operating frequency of a watch equipped with a quartz oscillator. The following steps are performed by a self-calibration circuit of the electronic watch device: from a first external pulse and a second external pulse received from a system external to the watch and separated by a measurement time, corresponding to a reference number of reference periods for a periodic calibration signal derived from the time-measurement signal and having a calibration frequency derived from the natural frequency of the quartz oscillator, determining a calibration parameter representative of a ratio between a calibration period and a reference period for the periodic calibration signal, and determining a constant inhibition parameter as a function of the calibration parameter.
