  • the invention also relates to a timepiece 400 comprising at least one such control device 100, and comprising a clock mechanism, which comprises motor means and triggering means 3 for controlling the activation of at least a first lift 1 and a second lift 2.
  • This part comprises at least one such control device 100, for regulating the torque consumed by a striking mechanism 200 or a minute repeater ringing mechanism that includes this part, and / or for the regulation torque consumed by a date mechanism 300 that includes this piece.
