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: Mechanical timepiece oscillator comprising, between a first element and a second inertial element, two distinct flexible strips returning the inertial element to a rest position in an oscillation plane, the projections of these strips crossing each other, in the rest position, at a point, through which passes the pivoting axis of the second solid inertial element, the embedding points of the strips in the first element and the second inertial element defining two directions in which each strip has a free length between its embedding points, and an axial distance between the pivoting axis and the the farthest of its embedding points, and, for each strip, the embedding point ratio is comprised between 0 and 1, and the vertex angle at the crossing point of the directions of the strips is less than 70°.

Abstract: 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.

Abstract: A timepiece mechanism including a first component and a second component configured to cooperate with each other in a relative motion on a trajectory in an interface area, wherein a first path of the first component includes magnetic and/or electrostatic actuation components, configured to exert a contactless stress on complementary magnetic and/or electrostatic actuation components included in a second path belonging to the second component. Throughout a monotonous relative movement of the second path with respect to the first path, interaction energy between the first component and second component has a variable gradient with at least one position of discontinuity of the gradient, which corresponds to a variation in the contactless stress, the position of discontinuity of the gradient corresponding, in a variant, to an abrupt variation in the contactless stress.
