摘要： A method for maintaining and regulating frequency of a timepiece resonator mechanism around its natural frequency, the method including: at least one regulator device acting on the resonator mechanism with a periodic motion, to impose a periodic modulation of resonant frequency or quality factor or a position of a point of rest of the resonator mechanism, with a regulation frequency between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency, the integer being greater than or equal to 2 and less than or equal to 10, and the periodic motion imposes a periodic modulation of the quality factor of the resonator mechanism, by acting on losses and/or damping and/or friction of the resonator mechanism.

摘要： A timepiece mechanism comprising a regulator, an energy distributing member a pallet fork controlled by the regulator to alternate in locking and releasing the energy distributing member, and a decoupling member elastically connected to the pallet fork and to the regulator. The decoupling member is arranged so as to oscillate between two stop elements.

摘要： A mechanism for adjusting an average speed in a timepiece movement comprises an escapement wheel and a mechanical oscillator, in which a plurality of blades, which are resiliently flexible in an oscillation plane, support and return a balance in such a way that this balance oscillates at an angle in the oscillation plane. A pallet fork comprises two rigid pallets which are rigidly connected to the balance and are arranged to co-operate alternately with a toothing of the escapement wheel when the balance oscillates at an angle.

摘要： 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°.

摘要： The present invention relates to a wristwatch comprising a mechanical clock movement with a tuning fork resonator. The oscillator preferably comprises a material A with a low internal friction. In the oscillator of the invention, the unwanted symmetrical oscillations are avoided, for example, by the choice of the materials from which the tuning fork is manufactured. According to preferred embodiments, the rod and/or fastening of the oscillator comprises a material having greater internal friction than that of said material A, such that the quality factor Q2 of the symmetrical oscillations is reduced, in contrast to the quality factor Q1 of the anti symmetrical oscillation mode.
