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.

Abstract: A magnetic clock escapement, and a regulating device, the escapement including a first circular network formed by N1 magnetic lines and a second circular network formed by N2 magnetic lines, N2 being different from N1. The first and second networks are superimposed to define a combined pattern having a magnetic Moiré effect. The combined pattern is coupled magnetically to at least one magnet of a resonator to pace operation of a mechanical clock movement. The first magnetic structure is carried by an escapement wheel and can rotate relative to the second fixed magnetic structure with an angular frequency F1. The combined pattern rotates with a greater angular frequency F2 and equal to the angular frequency F1 multiplied by the number N1 and divided by the number ΔN equal to this number N1 minus the number N2, F2=F1·N1/ΔN.

Abstract: A timepiece or watch includes at least one resonator, which includes at least one weight that oscillates with respect to a connecting element fixed to a structure of a timepiece movement. The weight is suspended from the connecting element by resilient crossed strips which extend at a distance from each other in two parallel planes. The projections of the strips on one of the parallel planes intersect at a virtual pivot axis of the weight, and define a first angle which is the apex angle opposite which there extends the portion of the connecting element that is located between the attachments of the crossed strips to the connecting element. The first angle is between 68° and 76°.

Abstract: A timepiece escapement mechanism includes a stopper between a resonator and an escape wheel set. The wheel set includes a magnetized track with an angular period of travel over which its magnetic characteristics are repeated. The stopper includes a magnetized or ferromagnetic pole shoe that is mobile in a transverse direction relative to the direction of travel of an element of a surface of the track. The pole shoe or the track creates a magnetic field in a pole gap between the pole shoe and the surface. The pole shoe is opposite a magnetic field barrier on the track just before each transverse motion of the stopper commanded by the periodic action of this resonator. The stopper is multistable and arranged to occupy at least two stable positions.

Abstract: A method for making a flexure bearing for an oscillator with an inertial element oscillating in a plane supported by flexible strips fixed to a stationary support returning it to a rest position includes: forming the bearing with basic strips in superposed levels, each having an aspect ratio of less than 10; breaking down the number of basic levels into a plurality of sub-units, each including one or two strips joining a basic support and a basic inertial element, which are made by etching substrates; assembling the sub-units by joining their basic inertial elements; and fixing the basic supports to the support, directly or via translational tables along one or two in-plane translational degrees of freedom, of lower translational stiffness than that of the sub-unit.
