    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 timepiece includes a mechanical oscillator, formed by a balance and a piezoelectric balance spring, and a regulating device for regulating the frequency of the mechanical oscillator which is arranged to be able to produce time-separated regulating pulses, each consisting of a momentary decrease in an electrical resistance applied by the regulating device between two electrodes of the balance spring relative to a nominal electrical resistance. Each regulating pulse produces a variation of rate which varies as a function of its moment of starting in a half-period of the mechanical oscillator, the characteristic function of this variation of rate relative to the moment of starting of at least one regulating pulse respectively in at least one half-period of the mechanical oscillator being negative in a first temporal zone of at least one half-period and positive in a second temporal zone of at least one half-period.

    Abstract: A recharging device for an electronic or electromechanical watch equipped, on the one hand, with a device for the storage of electrical energy for powering electronic components of the watch and, on the other hand, with an auxiliary source of electrical energy adapted to power the device for the storage of electrical energy for recharging thereof. The device includes a casket provided with a support for receiving the watch. The device further includes at least one source of energy configured to supply energy to the auxiliary source of electrical energy, when the watch is placed on the receiving support, so that the auxiliary source of electrical energy converts the received energy into electrical energy and delivers a charge for maintaining a predetermined level of power supply voltage to the device for the storage of electrical energy.

    Abstract: An horological movement includes an analogue time display, a geartrain, a barrel and an electromechanical oscillator, which is formed of a resonator, including a balance and a piezoelectric balance-spring, and a mechanical escapement, and further includes an electronic control circuit connected to an electrical energy source and arranged to be able to control the application of an electrical voltage on at least one electrode of the piezoelectric balance-spring so as to generate driving electrical pulses for the oscillator. The horological movement is configured such that the barrel is capable, in a first main state, of maintaining alone a functional oscillation of the oscillator with a first amplitude, while in a second main state, the electronic control circuit powers the piezoelectric balance-spring to maintain, partially or fully, the oscillation of the resonator with a second amplitude greater than the first amplitude for any spatial orientation, the second amplitude being preferably constant.
