A timepiece component including a shaft-like portion including at least one pivot about a pivot axis, wherein at least the constituent material of this shaft-like portion is a ceramic or similar non-magnetic type material, the shaft-like portion includes a plurality of recesses evenly arranged or regularly distributed about the pivot axis, and has its centre of inertia on the pivot axis, and the shaft-like portion includes a collar forming its largest diameter with respect to the pivot axis, which collar includes a parting line of the shaft-like portion, which parting line is substantially perpendicular to the pivot axis, the recesses pass right through the collar, and at least one recess contains an injection point for the material.

A timepiece includes a case having a cylindrical shape, a case back including a transmissive region and covering one opening of the case, and a movement accommodated in the case, the movement including a timepiece component, a first magnetic shield component covering at least a portion on the case back side of the timepiece component, and a second magnetic shield component covering at least a portion of a side surface of the timepiece component. The first magnetic shield component includes an overlapping region overlapping the second magnetic shield component in plan view as viewed from a direction perpendicular to the case back, and the first magnetic shield component and the second magnetic shield component are disposed in contact with each other in the overlapping region.

A protective shroud for a dive watch having a transparent lenticular element configured to enlarge an image appearing on a dial of the dive watch. The shroud can include a rib that distances the lenticular element from the dial, and a flange that extends around the lenticular element and includes two slots for fixing a strap of the dive watch. The shroud can be made of a single piece of elastic material.

A horological movement includes a resonator and an escapement wheel with flexible teeth, and an anchor formed of two mechanical pallets capable of abutting, when the anchor switches between its two rest positions, with any one of the flexible teeth depending on the angular position of the escapement wheel. Each flexible tooth is arranged to bend by undergoing an elastic deformation under a radial force that can be exerted by one of the two mechanical pallets abutting against this flexible tooth while the escapement wheel has an unfavourable angular position and the resonator is braked by the anchor. Each tooth has an elastic capacity to elastically absorb, in a radial direction, most of a maximum mechanical energy that the mechanical resonator may have during normal operation of the horological movement, to avoid breakage or deterioration of the escapement.

A dewar device (1) for mechanical and/or functional components (2) of a watch (3), the device (1) being provided with a bracelet and a casing (4) including an enclosure (5) wherein it is possible to arrange a case (6) of the watch (3) and at least one reversible connecting element (7) fixing the watch (3) case (6) in the enclosure (5) of the casing (4) while keeping it remote from all the elements (10a, 10b, 10c) of the casing (4) defining this enclosure (5), the at least one reversible connecting element (7) being provided with a body forming a structure (8) including at least one recessed area (9).

A Dewar device for mechanical and/or functional components of a watch, the device being provided with a bracelet and a casing including an enclosure wherein a case of the watch can be disposed so that a crystal of the case is arranged opposite a crystal of all the elements of the casing defining this enclosure and at least one fastening device fastening the watch case in the enclosure of the casing by keeping it remote from all the elements of the casing defining this enclosure, the Dewar device including a device for actuating at least one push button by rotating a pivoting bezel of the casing.

An electronic watch including a movement, and the movement includes a movement main body, a plate manufactured by a ferromagnetic metal, and a hook having flexibility, and the plate includes an engagement part that protrudes from the rear surface of the plate and which is configured to accommodate one end part of the hook, and the one end part of the hook is configured to be accommodated by the engagement part by elastically deforming the hook, and the other end part of the hook is fixed to the movement main body.

An antiferromagnetic alloy consisting of: between 10.0 and 30.0 wt.-% manganese, between 4.0 and 10.0 wt.-% chromium, between 5.0 and 15.0 wt.-% nickel, between 0.1 and 2.0 wt.-% titanium, the remainder being iron and residual impurities, the alloy being free of beryllium.

A timepiece resonator mechanism includes a structure and an inertial element oscillating around an axis and subjected to restoring forces exerted by a plurality of elastic blades, each fixed directly or indirectly to the structure at a first end and fixed directly or indirectly to an inertial element at a second end. The elastic blade extends in a perpendicular plane to the pivot axis and is deformable substantially in this plane, where this resonator mechanism includes an axial stop including at least a lower axial stop and/or an upper axial stop, and the axial stop is arranged for the protection of the blade resonator mechanism against axial shocks in the direction of the axis.
