Abstract: A magnetic microactuator (100) including a coil (6; 61; 62) controlling the axial movement of a sliding block (30) including at least one permanent magnet (2) joined or aligned with a ferromagnetic or magnetised rear arbor (42) and guiding the field lines of the magnetic field of revolution in the axial direction (D) through the coil (6; 61; 62) wherein circulates the sliding block (30), up to a rear end (43) of said rear arbor (42) that tends to cooperate by magnetic attraction with at least one first ferromagnetic restoration element (8), located in the vicinity of a rear face (25) of the structure (20) of the microactuator (100), in order to bring said sliding block (30) back into a rear end-of-travel position when no coil (6; 61; 62) is powered.

Abstract: A timepiece assembly includes a watch having a mechanical movement and an analogue time display, the running of which is set by a mechanical resonator, and a support for the watch. To correct a time displayed by the analogue display, the timepiece assembly includes a correction system which is formed by a mechanical device incorporated into the watch and by an electrical device incorporated into the support. The mechanical device includes a magnet supported by an elastic blade and is arranged in the watch to brake the oscillating mechanical resonator, for example by applying periodic braking, or to momentarily stop its oscillation by exerting a magnetic force on the magnet with a magnetic field produced by a coil of the electrical device and passing through the case of the watch, to carry out essentially a set correction of the time displayed.

Abstract: A mechanism including a magnetic gear including a first wheel, a second wheel and a third wheel. The first wheel is provided with permanent magnetic poles which are arranged so as to form the magnetised teeth of a first magnetic toothing. The second wheel and the third wheel are provided with teeth made of a soft ferromagnetic material respectively defining a second magnetic toothing and a third magnetic toothing, each with a number of teeth that is greater than that of the first magnetic toothing and having a magnetic coupling with this first magnetic toothing. The second magnetic toothing is directly coupled with the first magnetic toothing and with the third magnetic toothing thanks to the magnetic fluxes provided by the magnetised teeth of the first toothing and the teeth of the second magnetic toothing are magnetically separated from one another.

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.
