A wristwatch and a power saving method thereof are provided herein. The wristwatch comprises: a time indicating device, configured to provide time information; a housing, defining a receiving room; a short distance communication module disposed in the receiving room, configured to implement short distance wireless communication with an external device, the communication module comprising: a security element, configured to process user security data; and a first coil, coupled to the security element and configured to transmit electromagnetic signals to communicate with the external device; the wristwatch further comprising: a second coil, coupled to the communication module, configured to sense an external magnetic field to generate a sensing signal, the sensing signal provided for controlling the communication module to be turned on or off to enable or disable transmission of the electromagnetic signals of the first coil. The wristwatch can reduce power consumption.

Wristwatch and power saving method thereof

A smart wristwatch structure includes a glass, a dial, a watch case, a bottom case, a movement, an antenna, a functional module, and a dedicated battery. The dial, the watch case, and the bottom case construct an accommodating space from top to bottom. The antenna is adhered to a lower surface of the glass. The functional module is disposed in the accommodating space for wirelessly communicating with a mobile terminal. The dedicated battery provides power for the functional module or the movement. In the smart wristwatch structure, signals are not shielded, and the thickness of the watch case is not increased significantly.
