Abstract (en)

[origin: CN115494716A] The invention relates to a natural escapement for a timepiece movement that performs a series of operating cycles, each operating cycle comprising a first and a second half cycle of a balance mechanism comprising a balance, a balance plate being adjusted on the axis of the balance, the natural escapement comprising a first escapement wheel arranged to be driven by a second wheel, the first escapement wheel in turn drives the second escapement wheel, a balance plate carrying a balance pin, by means of which the balance plate causes the anchor pallet to pivot in both first and second half cycles, a first lever pivoting about a pivot axis being connected to a first arm of the anchor pallet via at least one pivot joint, the anchor pallet comprises a second arm extending out of a second lever, the first and second levers being arranged to temporarily lock the first and second escapement wheels, respectively, during a second and first half-cycle of one operating cycle, the pivoting displacement of the first and second levers being limited. The invention also relates to a timepiece movement comprising such a natural escapement.
