摘要： A horological movement including a mechanical resonator and a hybrid escapement including an escapement wheel and a pallet assembly with at least one magnetic pallet-stone formed of a magnet and associated with a mechanical banking, the escapement wheel including a periodic magnetised structure defining increasing gradients of magnetic potential energy for the magnetic pallet-stone, and protruding parts associated with the increasing gradients of magnetic potential energy. When the force torque is equal to a nominal force torque or has a value within at least an upper part of a given range of values, one of the protruding parts of the escapement wheel is subjected to at least one shock on the mechanical banking of the pallet assembly after the magnetic pallet-stone has climbed any one of the increasing gradients of magnetic potential energy, thus dissipating at least partially a kinetic energy of the escapement wheel.

摘要： A direct impulse free escapement mechanism for a timepiece includes: an escapement wheel with peripheral teeth; a locking device including a locking pallet engaging an escapement wheel tooth in a locking position of the locking device; and a control pallet actuated by a pivoting regulating organ to engage a complementary unlocking organ of the locking device to release the locking device from the escapement wheel in an unlocking position at each alternation of the regulating organ. Also included are impulse pallets attachable to the regulating organ, cooperating on an impulse plane with a tooth of the escapement wheel to transmit a direct impulse to the regulating organ. The locking device is drawn by the escapement wheel in each locking position. The teeth of the escapement wheel and the impulse pallets are configured so the impulses occur outside the plane of the escapement wheel. A corresponding timepiece is also disclosed.

摘要： The micromechanical clockwork part is cut from a plate-like silicon substrate. The cut edges of the part include portions intended to serve as contact surfaces arranged to slide against corresponding contact zones of another micromechanical part in a clockwork piece. The cut edges have a ribbed surface including an alternating set of ribs and furrows, the ribs and the furrows being straight and each contained in a plane parallel to the plate. Moreover, the ribs and furrows which the cut edges have form a stepped pattern on the cut edge, with first intervals in which the spacing separating the ribs from one another is equal to a first distance, and at least one second interval in which the spacing between the ribs is equal to a second distance different from the first distance.

摘要： A timepiece regulator includes a detached lever escapement mechanism and a resonator with a quality factor Q including an inertia element. An impulse pin is integral with an inertia element and cooperates with a fork of the lever. The inertia element is subjected to the action of an elastic return directly or indirectly fixed to the plate and arranged to cooperate indirectly with an escape wheel set included in the escapement mechanism. The resonator mechanism is a resonator with a virtual pivot rotating about a main axis, with a flexure bearing subjected to the return force of at least two flexible strips attached to the plate, defining together a virtual pivot with a main axis. The lever pivots about a secondary axis. The lever is made of silicon added to an arbor pivoted with respect to the plate.

摘要： A watch has a mechanical movement with a force control mechanism arranged in a going train of the mechanical movement between an energy source and an escape wheel set connected to an oscillating oscillator to drive the escape wheel set always in the same direction of rotation. The escape wheel set meshes with a seconds wheel. A rotating locking element is arranged to cooperate with a stop member connected to this seconds wheel in order to lock this going train in a stop mode or to release this going train in a jump mode depending on the angular position of this seconds wheel. A flexure bearing with elastic strips is attached on the one hand to the seconds wheel and on the other hand to the movement support. The pre-wound flexure bearing is arranged to drive in rotation the seconds wheel and the escapement mechanism connected to the oscillator at each half-oscillation of the oscillator in the stop mode.

摘要： A timepiece movement including, fixed on a same plate, a gear train subjected to a torque in a timepiece movement, and an energy storage to deliver a torque to the gear train for actuating a mechanical mechanism synchronizing rotational speed of the gear train with a resonator having a given natural resonant frequency included in the timepiece movement. The resonator is an annular resonator including a ring disposed around an axis. The ring is arranged to be periodically deformed under an action induced by motion of a drive member, included in this mechanism, and the drive member is driven in a pivoting motion, directly or indirectly, by the gear train.

摘要： A timepiece escapement mechanism, including a balance having no roller and an escape wheel, between which impulses are transmitted by a flexible, single-piece mechanism, connected by at least one flexible strip to a fixed structure or to the wheel. Oscillation is maintained by a balance spring ending in a balance spring stud which is mobile during operation, and which is guided by a flexible guide member with flexible strips, and whose center of rotation is coaxial to the balance, the balance spring stud receiving a pin which is mobile in a cam path of the wheel. During the oscillations, the balance spring stud is moved relative to its locking position under action of force exerted by the balance spring, and the pin maintains and regulates the oscillation.
