Abstract: 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.

Abstract: A wearable object (42) including an electronic unit and a power supply unit formed by an electromechanical converter (6A) which includes a rotor (44) carrying first magnets (10A), a mechanical resonator (12A) provided with an inertia mass (46) capable of oscillating at a relatively high resonant frequency and carrying second magnets (20), and coils arranged so that, when the mechanical resonator is oscillating, an induced voltage is generated in these coils. The electromechanical converter is arranged so that the first magnets and the second magnets can, during a rotational drive of the rotor, interact magnetically so as to apply to the inertia mass, momentarily or temporarily, a magnetic force torque allowing to excite the mechanical resonator, in order to generate at least one oscillation of this mechanical resonator at its resonant frequency in order to generate a relatively high induced voltage allowing to recharge an accumulator.

Abstract: A testability method (500) for testing the operation of a thermoelectric element (110) of a thermoelectric watch (100) including the thermoelectric element (110), a power circuit supplied by primary storage elements (101) and secondary storage elements (102) so as to move at least one moveable element (190) or display information on an electro-optical display device. The testability method (500) includes steps of applying a heat source (540) to the thermoelectric element (110) so as to make it possible to electrically charge (550) or recharge (550) the secondary storage elements (102) in order to move at least one moveable element (190) or display information on an electro-optical display device, and thus check the functionality of the thermoelectric element (110).
