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.

Abstract: A thermoelectric watch includes a thermoelectric generator; a voltage booster connected to the thermoelectric generator, and an energy management circuit connected to the voltage booster and configured to control the charging of at least one energy storage element. The energy management circuit includes an output configured to change from a first logic state to a second logic state when the thermoelectric generator starts generating electrical energy, and to change from the second logic state to the first logic state when the thermoelectric generator finishes generating electrical energy.

Abstract: A device is disclosed for verifying the state of a watch and resetting it to the correct time. In a case of the device, a watch can be disposed on a watch support, which can be moved from a position without measurement to a measurement position in a vision system, or vice versa. In a position without measurement, the watch on its support can be observed from the outside of the case of the device through at least one electronic shutter activated or an optical valve activated to be in a transparent state, whereas in the measurement position, the electronic shutter or the optical valve is deactivated to be made opaque.
