Abstract
An automatic pawl winding mechanism for a watch movement has a rotor solidly attached to a rotor wheel and oscillating about the axis of a rotor pivot, a pawl wheel to which an oscillating motion of rotor is transmitted by the rotor wheel being pivoted about the axis of a pawl wheel shaft, at least one pawl being eccentrically attached to the pawl wheel shaft, and an automatic wheel cooperating with the pawl or pawls. The oscillating motion of the rotor wheel is thus transformed into a unidirectional rotary motion of the automatic wheel, and this rotary motion is transmitted to a ratchet wheel via a transformation gear train. The rotor, the gear train from the rotor with rotor wheel to the pawl wheel with the pawl or pawls is mounted on an independent rotor bridge while no other organ of the mechanism is mounted on this bridge.
