    Abstract: A horological movement includes an escapement with a magnetic system to generate magnetic force impulses, so as to sustain the oscillation of the mechanical resonator associated with the escapement. In order to make possible an effective self-starting of the assembly formed of the mechanical resonator and of the escapement during a winding of the barrel, after a stop of the horological movement due to the unwound barrel spring, the escape wheel includes teeth and the pallet assembly includes two mechanical pallet-stones arranged to receive, upon starting, at least one mechanical force impulse of the escape wheel via one of the teeth thereof, the mechanical force impulse generating a starting force torque on the pallet assembly that is transmitted to the balance of the mechanical resonator to begin an oscillation of the latter so that the assembly can operate normally after a starting phase.

    Abstract: The horological movement includes a mechanical resonator and an escapement including an escapement wheel, which has a plurality of teeth, and an anchor formed by a stick and two arms having respectively two mechanical pallets likely to come into contact, when the anchor is subject to an alternative movement, with any of the teeth according to the angular position of the escapement wheel. To avoid damage to the escapement during rocking of the anchor while the escapement wheel is positioned in an unfavourable angular position, the anchor is arranged, during the rocking of this anchor, to be able to bend being subjected to an elastic deformation. The anchor has an elastic capacity between each of the two mechanical pallets and a fork of the anchor, enabling it to absorb elastically, during the elastic deformation, a maximum mechanical energy that the mechanical resonator can have during the normal functioning of the horological movement.

    Abstract: A bracelet including two strands provided with a fastening system which includes at least one longitudinal groove on one of the two strands and at least one longitudinal protuberance on the other strand. The material and the shape of the groove and of the protuberance are configured such that these two elements interlock under pressure exerted by the bracelet user, over two overlapping portions of the bracelet strands. The connection between the strands can easily be separated, preferably by peeling the upper strand away from the lower strand. The bracelet is continuously adjustable in length, without requiring heavy or complex elements.

    Abstract: A watch includes a control member capable of managing a primary function of the watch, such as a rotating crown or a push-piece, as well as a magnetic ball that can be manually pivoted by the user about the centre thereof. A 3D magnetic sensor is arranged in the watch to detect the orientation of the magnetic field emitted by the magnetic ball, in addition to a processor for converting an electric signal generated by the magnetic sensor into an instruction for managing one or more other electronic functions of the watch. The magnetic ball is partially arranged inside the control member such that it is accessible to a user. The watch can further comprise a proximity sensor for detecting the axial position of the control member relative to the middle of the watch.

    Abstract: A watch includes a control member, for example a crown or a head of a push-piece, which is mounted in a resilient manner on the outer end of an elongated element projecting outside the middle, such that a user can tilt in a self-reverting manner the control member in two dimensions orthogonal and perpendicular to the central axis of the elongated element. At least one proximity sensor is incorporated into the middle of the watch, in a location allowing this proximity sensor to produce an electric signal that represents the tilting of the control member about an axis that is perpendicular to the central axis. A processor generates at least one instruction on the basis of the electric signal provided by at least one proximity sensor, for example to allow the user to browse a menu or a calendar displayed on a digital screen.

    Abstract: A system and method to determine an angular movement of an arbor integral with a crown of a watch, the arbor being rotatable in a longitudinal direction. Included is a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector. Each emitter/detector pair includes a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals and determine a parameter relating to the angular movement of the arbor. The rotating reflector's visible outer surface changes when the reflector rotates on itself in a regular manner, such that the representative electrical signal generated by said detector of the pair has a substantially sinusoidal shape when the reflector rotates on itself in a regular manner in a same direction of rotation.

    Abstract: A disassembly bench is for unlocking and disassembling a first component and a second component of a watch with secured fastening including handling devices to transmit a relative disassembly movement between this first component and this second component. The bench also includes centrifuging devices and/or pneumatic or hydraulic devices for simultaneous application of a centrifugal force and/or an overpressure or an underpressure to such a watch to press into a position of free passage one or more slides arranged to immobilize this first component and this second component in a locked position. A watchmaking set includes such a disassembly bench and such a watch with secured fastening.
