A horological detent escapement for a horological movement arranged to transmit a torque from said horological movement to an oscillating regulating organ of said horological movement, the regulating organ comprising a first mobile body and the escapement comprising a second mobile body and an escapement wheel. Said escapement wheel being arranged so as to transmit, during a half-phase of each oscillation of the regulating organ, a torque to said regulating organ via a direct impulse. The second mobile body comprises an indirect impulse means arranged so as to be in contact with the escapement wheel during normal operation and be out of contact during the other half-phase of each oscillation of the regulating organ when the escapement wheel does not transmit torque to the regulating organ, so as to transmit torque to said regulating organ via an indirect impulse, following an inadvertent movement or inadvertent stoppage of the horological movement.
