Automatic pawl winding mechanism

Automatic pawl winding mechanism for watch movements having a rotor (1) solidly attached to a rotor wheel (2) and oscillating about the axis of a rotor pivot (3), a pawl wheel (4) to which an oscillating motion of the rotor (1) is transmitted being attached rotatably about the axis of a pawl wheel shaft (7), at least one pawl (5a, 5b) being attached eccentrically to the axis of the pawl wheel shaft (7), and an automatic wheel (11) cooperating with the pawl or pawls (5a, 5b) in such a manner that the oscillating motion of the rotor wheel (2) is transformed into a unidirectional rotary motion of the automatic wheel (11) and that this rotary motion is transmitted to a ratchet wheel (13) via a transformation gear train (12), characterised in that the rotor (1) together with the gear train from the rotor (1) with its rotor wheel (2) to the pawl wheel (4) with the pawl or pawls (5a, 5b) is mounted on an independent rotor bridge (9) while no other organ of the mechanism is mounted on this independent rotor bridge (9).
