Abstract (en)

[origin: CN104730897A] Timepiece escapement mechanism (10) including a stopper (30) between a resonator (20) and an escape wheel set (40). This wheel set (40) includes a magnetized track (50) with an angular period of travel (PD) over which its magnetic characteristics are repeated, this stopper (30) includes a magnetized or ferromagnetic pole shoe (3), mobile in a transverse direction (DT) relative to the direction of travel (DD) of an element of a surface (4) of this track (50), and this pole shoe (3) or this track (50) creates a magnetic field in a pole gap (5) between this pole shoe (3) and this surface (4), and this pole shoe (3) is opposite a magnetic field barrier (46) on this track (50) just before each transverse motion of this stopper (30) commanded by the periodic action of this resonator (20), this stopper (30) being multistable, arranged to occupy at least two stable positions.
