Abstract: A watch including a gasket (18) arranged at the periphery of the glass (14), an intermediate portion (20) laterally surrounding the analogue display and defining a radial surface forming an axial stop for the glass, a solar cell (30) extending at least mostly between the lower level of the dial and the glass and being arranged behind the intermediate portion, which is formed at least partially by a translucent or transparent material and configured to make it possible for the incident light to propagate in the intermediate portion and to subsequently reach the solar cell. The gasket is also formed at least mostly by a translucent or transparent material and it forms with the intermediate portion axially a continuous medium. In variants, the gasket is arranged axially adjacent to the intermediate portion or it is axially separated from the intermediate portion by a translucent or transparent intermediate medium.

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: 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.

Abstract: A timepiece and method for mounting a generator in the timepiece, this generator being formed of a rotor with permanent magnets and two coils. A supporting structure is preassembled with the rotor and an electronic module including the two coils is preformed. The method includes the following successive steps for laterally mounting the electronic module in the supporting structure so as to form the generator; assembly of an electronic module support with the supporting structure to form an articulation; rotation of the electronic module thanks to the articulation to bring the two coils closer to the axis of rotation of the rotor, so that these two coils are finally each located in a functional position at the same distance from the axis of rotation of the rotor; fastening of the electronic module to block the articulation after said rotation and thus maintain this electronic module in a functional angular position.

Abstract: An inertial mass with adjustment of inertia and/or unbalance for a horological resonator, including a plurality of mobiles for adjusting inertia and/or unbalance, toothed or fluted, each mounted pivotably about a mobile axis with respect to a flange that the inertial mass includes, and with a centre of mass off-centre with respect to this mobile axis, each mobile cooperating by meshing with an inertia and/or unbalance adjustment crown, toothed or fluted, under a permanent constraint exerted by an elastic return force exerted by the crown and/or the mobile.

Abstract: A motor drive unit for driving a direct current electric motor including a moving part equipped with permanent magnets. The motor drive unit, which is powered by a voltage supply source, includes a switch circuit, an inductor circuit and a capacitor circuit including a set of capacitors. By selectively opening and closing the switches of the switch circuit, a series of consecutive low energy pulses can be generated such that the power consumption of the motor drive circuit is minimized.

Abstract: Timepiece movement fitted with an electromagnetic transducer comprising at least one coil and a rotor formed of a central shaft, of two magnetic plates that are mounted on the central shaft and of a plurality of bipolar magnets which are axially polarized and mounted on at least one of the two magnetic plates, said at least one coil penetrating at least partially into a circular space which is defined by the rotor between its two magnetic plates and left free by this rotor. The central shaft comprises a pinion which engages with a wheel of the timepiece movement, this pinion being arranged between the two magnetic plates and said wheel being partially arranged between the two magnetic plates, in an angular sector of the circular space that is left free by the electromagnetic transducer, so as to engage with the pinion. Advantageously, said wheel has a roller that is almost or entirely non-conductive and a non-magnetic staff.

Abstract: Strip resonator for a mechanical watch movement, comprising a structure, an oscillating inertial element, and elastic strips forming a flat bearing for the inertial element, and a flat, anti-shock device arranged to protect each strip from rupture in the event of a shock, and including a first prestressed flexible element arranged to allow a variation in length during the expansion or contraction of a strip within a range of lengths corresponding to normal operation of this strip under the action of a stress of intensity lower than a first threshold, and to prevent the expansion or contraction of this strip when it is subjected to a tensile or respectively compressive stress of intensity higher than the first threshold, and the resonator includes, for the three-dimensional anti-shock protection of the strips, in an axial direction perpendicular to a main plane, axial protection means, which include, on the one hand, axial banking members for limiting the axial travel of at least one inertial element, and on the other hand, an axial anti-shock device comprising a second axially prestressed flexible element.
