Abstract (en)
[origin: EP1914604A1] The movement has a barrel with an output torque variable based on its charging state. A compensation device transmits a constant torque to a mechanical oscillator irrespective of the state of the barrel, and has a cam (12) with a radius variable based on the variations of the output torque. The device has an intermediate connection mechanism to assure sliding-less kinematic connection between a periphery of the cam and the gear-train. The mechanism has a lever (13) to carry a mobile wheel (10) with a permanent kinematic connection with a wheel (9).
