Abstract (en)

[origin: EP2506091A2] The mechanism has an impulsion lever (8) pivoted on a part of a frame of a timepiece movement and co-operating with an escapement gear (1) and control elements. The control elements are fixed to an arbor of a hairspring. An outer end (11-1) of a constant force auxiliary spring (11) i.e. helical spring, is fixed on the part of the frame of the movement, while an inner end of the auxiliary spring is angularly fixed to the impulsion lever. The impulsion lever is mounted on the movement so as to be angularly and axially displaceable with respect to the frame of the movement. An independent claim is also included for a timepiece movement.
