Abstract
A power indicator device () of a thermoelectric generator of a watch. The indicator device includes a first gas fluid reservoir (), a second gas fluid reservoir (), and at least one tubular conduit () 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 () 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 () a liquid forming a barrier to the gas fluid of the two reservoirs and allowing, in a display portion () 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.
