A power indicator device (1) of a thermoelectric generator of a watch. The indicator device includes a first gas fluid reservoir (2), a second gas fluid reservoir (3), and at least one tubular conduit (4) connecting the two reservoirs. The first reservoir is placed on an upper surface of the thermoelectric generator in a watch case, while the second reservoir (3) is placed on a lower surface of the thermoelectric generator in contact with the back of a watch case. The tubular conduit is of the capillary type and comprises in an intermediate portion (9) a liquid forming a barrier to the gas fluid of the two reservoirs and allowing, in a display portion (24) visible from the outside of the watch case, to provide an indication of the power of the generator by measuring the temperature difference of the two reservoirs.

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.
