Abstract (en)
[origin: US2017336761A1] 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.
