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.

Abstract: A timepiece resonator mechanism with a pivoting weight pivoting about a virtual axis, and including a flexure pivot mechanism and a first and second fixed support to which is attached, by a first resilient assembly and respectively a second resilient assembly which together define the virtual axis, a rotary support carrying the pivoting weight, this flexure pivot mechanism is planar, the first resilient assembly includes, on either side of the virtual axis, a first outer flexible strip and a first inner flexible strip, joined to each other by a first intermediate strip stiffer than each of the latter, together defining a first direction passing through the virtual pivot axis, and the second resilient assembly includes a second flexible strip defining a second direction passing through the virtual pivot axis.

Abstract: Timepiece movement including a flexible strip resonator cooperating with a magnetic escapement mechanism, wherein an escape wheel set includes tangential magnetized areas repelling first magnetized areas of an inertial element of the resonator, this movement includes isochronism correction means combining the first magnetized areas and compensating magnets on the escape wheel set, each arranged in proximity to a tangential magnetized area and producing a leakage field in a different direction from that of the field of the tangential magnetized area, the leakage field intensity being low compared to that of the field of the second tangential magnetized area, and this leakage field interacting with one of the first magnetized areas to produce a low variation in the operation of the resonator mechanism.

Abstract: Timepiece sub-assembly comprising a component made of micromachinable material comprising an attachment area with a peripheral contact surface, and a shell element deformable between two shapes, one contracted and one expanded, arranged to hold the attachment area inside a housing with at least one degree of freedom, and which comprises a complementary contact surface arranged, in its contracted shape, to exert a clamping force on the contact surface and to securely immobilise the attachment area in all directions, the shell element comprising a first element and a second element that are movable with respect to each other in its expanded shape, each comprising a complementary contact surface, and comprising clamping means for holding the first and second elements clamped together in its contracted shape.

Abstract: Timepiece oscillator, comprising a sprung balance assembly including a balance with a rim, which is returned by a balance spring and pivoted with respect to a structure, on a first side by a torsion wire, fixed by an anchoring element to the structure, and on a second side, opposite to the first side, by a contactless magnetic pivot, the balance comprising a first pole embedded with the balance and the torsion wire, this first pole having a symmetry with respect to the axis of the sprung balance assembly, and cooperating with a second pole comprised in the structure, for the magnetic suspension of the first pole, and to exert on the distal end of the torsion wire, opposite to this anchoring element, a magnetic force for tensioning the torsion wire.
