Disclosed is an escapement mechanism with a locking anchor for a timepiece including a sprung-balance regulating organ, including an escapement wheel provided with a series of peripheral teeth, and a locking anchor including first and second locking pallets arranged respectively at one end of first and second arms to allow alternately engaging a tooth of the escapement wheel at each rotation step of the escapement wheel and of the anchor about their respective axis of rotation. This mechanism includes an impulse pallet adapted to be fixed to one the regulating organ to transmit an impulse by sliding a tooth of the escapement wheel on an impulse plane of the impulse pallet once at least every two oscillations of the regulating organ while the locking anchor includes a connecting member for permanent kinematic engagement in rotation to the regulating organ. Also disclosed is a timepiece incorporating such an escapement mechanism.

Disclosed is a timepiece blocking device including first and second mobile parts kinematically connected to one another, the first mobile part including a drive device, the second mobile part including a stopping device; a rotating drive member turning in a single direction and cooperating with the drive device to displace the first mobile part, and thus the second mobile part, alternately in opposite directions; and a rotating blocking member tensioned and cooperating with the stopping device to be blocked by the second mobile part and released at determined times by the displacements of the second mobile part. Cooperation between the rotating blocking member and stopping device immobilizes the mobile parts when the rotating drive member does not cooperate with the drive device. In normal operation, the rotating drive member contacts the first mobile part only when cooperating with the drive device, i.e. over less than 60% of one revolution of the rotating drive member.
