Abstract: There is provided a device for regulating the operation of a horological movement, including a magnetic escapement, which includes a resonator and a magnetic escapement mobile turning about an axis. The mobile includes at least one magnetic track with a plurality of magnets having an angular dimension that is greater than their radial dimension. The resonator includes at least one magnetic element for coupling to the magnetic track. The coupling element extends radially relative to the axis of rotation, and has a contour with a portion oriented substantially angularly when the resonator is in the rest position. When the mobile is driven in rotation, each magnet penetrates beneath the coupling element and gradually accumulates some potential magnetic energy. The magnet then exits from beneath the coupling element through the portion and the coupling element receives a pulse located around its rest position.

Abstract: A horological resonator mechanism, including a structure carrying, via a flexible suspension, an anchor unit from which is suspended an inertial element oscillating about a pivot axis extending in a first direction Z, in a first degree of rotational freedom RZ, under the effect of the return forces of a flexure pivot including longitudinal elastic strips, each fixed to the inertial element and to the anchor unit, the flexible suspension allowing the anchor unit to move in five degrees of freedom, this resonator is a composite assembly made of at least two different materials, on the one hand for the flexure pivot, and on the other hand for the flexible suspension.

Abstract: A balance for timepieces includes a rim, a hub, and at least one arm connecting the hub to the rim. At least one portion of the balance is made of an at least partially amorphous metal alloy. The at least partially amorphous metal alloy is based on an element chosen from the group consisting of platinum, zirconium and titanium, and has a coefficient of thermal expansion comprised between 7 ppm/° C. and 12 ppm/° C. The balance can be manufactured by moulding. A resonator can include such a balance and a monocrystalline quartz balance spring.

Abstract: Isochronous pivot for a resonator including two flexible strips joining attachment points of a first and a second element, defining two strip directions, and a pivot axis, at the intersection of their projections or at their intersection, each strip having a free length between its attachment points, and an axial distance between the pivot axis and the attachment point thereof farthest from the axis, the attachment point ratio X=D/L being greater than one for each strip, the strip directions defining with the axis a first apex angle whose value in degrees is comprised between f1(X)=108+67/(10X−6), and f2(X)=113+67/(10X−6).

Abstract: A process for producing a metal alloy balance wheel by molding, the process including the following steps: a) making a mold in the negative shape of the balance wheel, b) getting hold of a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature, c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel, d) cooling the metal alloy to obtain a balance wheel made of the metal alloy, e) releasing the balance wheel obtained in step d) from its mold.
