  • Publication number: 20210356911
    Abstract: A horological movement includes a resonator and an escapement wheel with flexible teeth, and an anchor formed of two mechanical pallets capable of abutting, when the anchor switches between its two rest positions, with any one of the flexible teeth depending on the angular position of the escapement wheel. Each flexible tooth is arranged to bend by undergoing an elastic deformation under a radial force that can be exerted by one of the two mechanical pallets abutting against this flexible tooth while the escapement wheel has an unfavourable angular position and the resonator is braked by the anchor. Each tooth has an elastic capacity to elastically absorb, in a radial direction, most of a maximum mechanical energy that the mechanical resonator may have during normal operation of the horological movement, to avoid breakage or deterioration of the escapement.
