Claim 1:
2. The horological movement according to claim 1, wherein a plurality of rigid parts, integral with the escapement wheel, are respectively arranged behind the plurality of flexible projecting parts, relative to a normal direction of the step-by-step rotation of the escapement wheel, so that each flexible projecting part is retained by the corresponding rigid part during an impact, among said successive impacts, which may occur between said projecting part and either one of the two mechanical pallets, to prevent or limit a recoil of said projecting part during said impact in a tangential direction, relative to said axis of rotation of the escapement wheel, and allow dissipation of a portion of a kinetic energy that the escapement wheel has at the beginning of said impact.
