Abstract: A direct impulse free escapement mechanism for a timepiece includes: an escapement wheel with peripheral teeth; a locking device including a locking pallet engaging an escapement wheel tooth in a locking position of the locking device; and a control pallet actuated by a pivoting regulating organ to engage a complementary unlocking organ of the locking device to release the locking device from the escapement wheel in an unlocking position at each alternation of the regulating organ. Also included are impulse pallets attachable to the regulating organ, cooperating on an impulse plane with a tooth of the escapement wheel to transmit a direct impulse to the regulating organ. The locking device is drawn by the escapement wheel in each locking position. The teeth of the escapement wheel and the impulse pallets are configured so the impulses occur outside the plane of the escapement wheel. A corresponding timepiece is also disclosed.
