Abstract: A device for a timepiece, comprising a support, an inertial regulating member mounted so as to rotate relative to the support by an elastic suspension connecting said regulating member to the support. The regulating member comprises a number n of rigid portions interconnected in pairs by n elastic coupling links. The elastic suspension comprises n elastic suspension links respectively connecting each rigid portion to the support.

Abstract: A mechanical watch including an in-plane oscillator (1) with a tuning mass (2), the oscillator (1) including a receptacle (3) for the tuning mass (2), the tuning mass (2) having a first portion (2?) snugly fitting in the receptacle (3), a second portion (2?) with a thickness that is equal or substantially equal to a thickness of the first portion (2?), and a length as seen at right angles with reference to said thickness that is substantially greater than said thickness so as to provide that the tuning mass (2) is substantially planar and extends outside the receptacle (3) in a plane substantially perpendicular to the plane of the oscillator (1).

Abstract: The invention relates to a method of manufacturing a plurality of mechanical resonators in a manufacturing wafer, the resonators being intended to equip a regulating member of a timepiece, the method comprising the following steps: (a) fabricating a plurality of resonators in at least one wafer according to reference specifications; (b) measuring the actual frequency of each of the plurality of resonators; (c) determining the offset of the actual frequency of the resonators with respect to the reference specifications; and (d) applying on at least one of the resonators at least two masses from a series of tuning masses to compensate the offset of the concerning resonator to bring the resonator closer to the reference specifications.

Abstract: 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.
