The invention relates to a mechanism for adjusting an average speed in a clock movement, which comprises an escapement wheel (4) and a mechanical oscillator (7), in which a plurality of blades (23a, 23b), which are resiliently flexible in an oscillation plane, support and return a pendulum (6) so that said pendulum (6) oscillates at an angle in the oscillation plane. A pallet assembly (5) comprises two rigid pallets (13, 14) which are rigidly connected to the pendulum (6) and arranged to engage alternately with gear teeth (12) of the escapement wheel (11) when the pendulum (6) oscillates at an angle. Un mécanisme de réglage d'une vitesse moyenne dans un mouvement d'horlogerie comprend une roue d'échappement (4) et un oscillateur mécanique (7), dont plusieurs lames (23a, 23b) élastiquement flexibles dans un plan d'oscillation portent et rappellent un balancier (6) de manière que ce balancier (6) soit oscillant angulairement dans le plan d'oscillation. Une ancre (5) comprend deux palettes rigides (13, 14) qui sont rigidement solidaires du balancier (6) et agencées pour coopérer alternativement avec une denture (12) de la roue d'échappement (11) lorsque le balancier (6) oscille angulairement.
