Abstract: A horological movement includes a striking mechanism of a watch including a vibrating element and a device for striking the vibrating element including a hammer fastened cantilevered to a structure of the horological movement through blades of a flexible guide. The blades are arranged so as to extend according to directions parallel to an axis T tangent to the vibrating element.

Abstract: A timepiece includes a mechanical oscillator and an electromechanical transducer formed by an electromagnetic assembly including a coil and a magnet mounted on the balance of the mechanical oscillator. The induced voltage signal, produced by the electromagnetic transducer during each oscillation, exhibits, in a first half-alternation between the oscillator passes via the neutral position thereof, a first lobe of maximum amplitude having a first polarity and, in a second half-alternation following a passage via the neutral position, a second lobe of maximum amplitude having a second polarity opposite the first. An electric converter includes two power supply capacitors and a device for regulating the medium frequency of the mechanical oscillator. The first power supply capacitor is charged merely with a positive voltage whereas the second capacitor is charged merely with a negative voltage. A load pump is arranged to transfer electric loads between the two capacitors according to a time drift of the mechanical oscillator relative to a time base.

Abstract: A timepiece movement includes a magnetic escapement formed of a magnetic escape wheel with an annular magnetized structure and a pallet fork whose shaft is formed by a ferromagnetic material. The pallet shaft exerts on the escape wheel a magnetic disturbance torque due to the fact that the annular magnetized structure exhibits an angular variation of at least one defining physical parameter thereof, such that the magnetic attraction varies as a function of the angular position of the escape wheel and has a tangential component. A magnetic compensation pin is incorporated in the timepiece movement, this magnetic compensation pin being arranged such that the second magnetic disturbance torque that it exerts on the escape wheel exhibits an angular phase shift relative to the first magnetic disturbance torque generated by the pallet shaft, so as to compensate largely for this first magnetic disturbance torque.
