Abstract:
A horological movement including a mechanical resonator and a hybrid escapement including an escapement wheel and a pallet assembly with at least one magnetic pallet-stone formed of a magnet and associated with a mechanical banking, the escapement wheel including a periodic magnetised structure defining increasing gradients of magnetic potential energy for the magnetic pallet-stone, and protruding parts associated with the increasing gradients of magnetic potential energy. When the force torque is equal to a nominal force torque or has a value within at least an upper part of a given range of values, one of the protruding parts of the escapement wheel is subjected to at least one shock on the mechanical banking of the pallet assembly after the magnetic pallet-stone has climbed any one of the increasing gradients of magnetic potential energy, thus dissipating at least partially a kinetic energy of the escapement wheel.
