Torque smoothing for a timepiece, particularly with a striking mechanism

A timepiece comprising:

• at least one movement including main energy storage means for powering at least one resonator and arranged to continuously drive at least one output wheel set including at least one tooth;
• and
• at least one display mechanism arranged to be controlled by a said movement or by user action, said display mechanism being supplied with energy at least by said main energy storage means and/or by secondary energy storage means via said output wheel set, and said display mechanism including elastic return means gradually wound by means of said output wheel set and arranged to change the display at instants controlled by a said movement or by user action, by unwinding said elastic return means, the winding and unwinding cycle of said elastic return means corresponding to a variation in the torque used by said display mechanism at said output wheel set, which includes at least one tooth arranged to lift an intermediate movement-actuated release lever, comprised in said display mechanism, wherein said display mechanism includes a torque smoothing jumper which is arranged for discontinuous abutting engagement with said output wheel set, either directly, or via an intermediate train, and which a first spring tends to return into abutment on said output wheel set, in order to use, when said intermediate, movement-actuated release lever is not in mesh with said output wheel set, a torque equivalent to that used by said intermediate, movement-actuated release lever when it is in mesh with said output wheel set, so as to avoid jerks in the going train of said movement and to prevent any amplitude variation of said resonator.
