The bracelet includes arbors inserted into each of the holes in the side links, the head of the arbors being fitted into the housings of the central links and each having a grooved portion in proximity to the end thereof, and the central links include an opening giving access to the grooved portions, which are arranged to cooperate with a locking member designed to be inserted into the openings in the central links to maintain the assembly of the bracelet.
A watch case including a rotating bezel and a middle part, the bezel being mounted such that it is capable of moving in rotation on the middle part, the bezel and the middle part defining therebetween an annular chamber internally including a device for creating a friction torque between the bezel and the middle part, the device including a compressing member and a braking element, the compressing member exerting a compressive stress on the braking element under the effect whereof the braking element is pressed against the bezel.
A striking or musical watch with an acoustic waveguide arrangement. The striking or musical watch (1) includes an at least partially flexible waveguide (2) secured to a fixed part (8) inside the watch to guide the acoustic waves generated by a first portion (2′) of the at least partially flexible waveguide towards a radiating element. The radiating element can include a watch crystal (3) connected to a bezel (5) and a membrane (4) for connecting the bezel to a middle part (6) of a watch case. The flexible waveguide is configured to change the direction of acoustic vibration from the first portion to the radiating element.
Timepiece display mobile component (1) comprising at least one resilient strip (4) returned to a display axis (DA), to cooperate in a friction drive with an arbor (2) of a drive mobile component (3) of a movement (100) or a mechanism, about the axis (DA), this mobile component (1) includes a flange (5) comprising, facing each resilient strip (4), an aperture (6) for the insertion and guidance of a manual or robotic tool to allow the tool to move the resilient strip (4) away from its rest position, and to insert the mobile component (1) on an arbor (2) when the resilient strip (4) is sufficiently far away to allow this mobile component to pass, and to ensure a constant friction value of all the resilient strips (4) on the arbor (2) when they are in frictional cooperation with the arbor (2) and when the tool is no longer in contact with the resilient strips (4).
A date calendar display mechanism driven via a kinematic chain by a horological movement of a timepiece. A first and second date indicators, the first date indicator remaining still during a 24-hour period separating the passage from the last day of a month having 31 days to the end of the first day of the following month, the kinematic chain including a wheel continuously engaged with the horological movement and having a toothing via which the wheel meshes with a pinion which contributes to driving the first indicator, the wheel being, at one point, devoid of teeth such that, during the above 24-hour period, the wheel does not mesh with the pinion and remains still. A dual jumper pivots about an axis with a first beak via which it is engaged with a toothing of the first date indicator and, at a second beak via which it is engaged with a toothing of the pinion, the dual jumper being elastically held engaged with the first date indicator and with the pinion.

System for adjusting the position of a first toothed wheel set relative to a support on which the first toothed wheel set is pivotably mounted and timepiece comprising such a system
A system for adjusting the angular position of a first toothed wheel set relative to a support on which the first toothed wheel set is mounted such that it can pivot. The adjusting system includes an adjusting member allowing an action to be applied to an angular position of the first toothed wheel set so as to adjust the angular position of the first toothed wheel set relative to the support. A timepiece can include such an adjusting system.
A device for fixing a bracelet to a watch case includes at least one horn and a bracelet strand. The horn and the bracelet are held together by a bar. The horn includes a rigid blade arranged to fit together with at least one recess made in the bracelet strand. The at least one recess has an opening for receiving the blade during the placement of the bracelet strand so as to form a rigid link once the bar is put in place.
A Watch (500) including a movement (200) with a tourbillon (100) including a carriage (1) pivotally mounted about a tourbillon axis (DT) with respect to a structure (300) and carrying a balance (2) pivoting about a balance axis (DB) and arranged to cooperate in a reciprocating motion with a stop device (3) pivotally mounted on this carriage (1), and wherein this tourbillon (100) includes a fixed magnet wheel (50) fixed to this structure (300) and comprising at least one continuous magnetic track and/or comprising a series of magnets, this magnetic track being arranged to cooperate by magnetic repulsion and/or attraction with at least one magnet (33) comprised in this stop device (3) in a reciprocating motion of this stop device (3) with respect to this fixed magnetic wheel (50).
Timepiece striking mechanism, including a fixed structure supporting at least one gong or radiant element and a mobile hammer in a plane under the action of an activation mobile component controlling the pallet of the hammer (3) and the release thereof for the percussion of the gong, and including, for the suspension of the hammer, at least one planar flexible guide between the structure and the hammer (3) to allow movements of the hammer solely on the plane, forming the sole mechanical link between the structure and the hammer, and, more particularly, for the execution of a striking mechanism, the striking mechanism (drives the activation mobile component, and has same carry out a winding cycle during which it supplies constant quantity of energy to the flexible guide while driving the hammer before releasing same for the execution of the striking mechanism by percussion of the gong during letting down.
