摘要： Sub-assembly for watches, including an arbor including a magnetized or electrically charged surface pivoting inside a housing, and a pole piece subjecting this surface to a magnetic or electrostatic field about an axis, one pole piece cooperating axially with this surface to absorb a shock and then return the arbor to an operating position, and creating, in proximity to this surface, a magnetic or electrostatic field, which radially attracts the arbor towards a wall of the housing.

摘要： The timepiece movement comprises a pivoting element, a bearing for a pivot of this pivoting element and an anti-shock device associated with this bearing and including a resilient member arranged to exert a restoring force on at least one endstone. The anti-shock device further includes a magnetic system comprising two magnets having opposite polarities and a highly magnetically permeable element arranged between these two magnets and secured to one of them, the two magnets being respectively fixed to a support of the anti-shock device and to the resilient member and arranged to produce between them, in association with the highly magnetically permeable element, an overall force of magnetic attraction on a first section of a possible distance of displacement for the endstone in the event of a shock and an overall force of magnetic repulsion on a second section of this distance of displacement corresponding to greater distances of separation than those of the first section.

摘要： The vertical coupling/uncoupling device includes a switching member and a control member, the latter being arranged to pivot about an axis of rotation to be able to be driven in rotation step-by-step successively into a plurality of distinct angular positions. The control member and the switching member respectively include a first magnetic structure and a second magnetic structure arranged to exhibit a magnet interaction therebetween. These first and second magnetic structures are arranged such that, depending on the angular position of the control member, a first magnetic force or a second magnetic force is produced, these first and second magnetic forces being oriented along said axis of rotation but in opposite directions. The switching member is subjected to an alternate movement between its first and second stable axial positions when the second magnetic structure is driven in rotation step-by-step in said given direction of rotation.

摘要： The mechanical timepiece movement includes an escapement having a pallet-lever arranged to move alternately into abutment with two banking elements in locking periods. The pallet-lever carries at least a first permanent magnet and the timepiece movement further includes a first element and a second element of high magnetic permeability and a second magnet and a third magnet respectively integral with first and second elements of high magnetic permeability and each arranged on an opposite side to a first magnet relative to the respective elements of high magnetic permeability. This magnetic system generates, in a first part of a first half vibration of any vibration of the pallet-lever, an overall force of magnetic attraction, defining a magnetic draw additional to the mechanical draw generated by the escape wheel, and, in a second part of this first half vibration, an overall force of magnetic repulsion.

摘要： The timepiece mechanism comprises a rotating wheel set, a support element, a pivoting member mounted on the support element and magnetic return means for returning one portion of the pivoting member against a surface of the rotating wheel set. The return means comprise a first magnet carried by the pivoting member and a second magnet carried by the support element. The first and second magnets are arranged such that, in normal operation, the interaction of their respective magnetic fields generates a magnetic force oriented to return said pivoting member portion towards said rotating wheel surface. At least one of the first and second magnets is arranged to permit reversal of its polarity, preferably with the aid of a tool, and thereby of the direction of the magnetic force acting on the pivoting member, said magnetic force then tending to move said pivoting member portion away from said rotating wheel set surface, which makes it easy to handle the various elements of the timepiece mechanism.

摘要： The device for pivoting an arbor about a determined axis includes at least one magnetic bearing including a magnet which exerts a force of attraction on a pivot, made of magnetic material, of the arbor. Further, the bearing includes a magnetic flux centring structure arranged between the magnet and the pivot, and a support for the centring structure. This centring structure includes a peripheral portion and a central portion resiliently connected to the peripheral portion by at least one connecting element, the central portion being formed of a highly magnetically permeable material and having smaller dimensions than those of the magnet. The peripheral portion is rigidly force fitted to the support so that the central portion is centred on the pivot axis.
