Abstract (en)

[origin: EP2290476A1] The corrector (10) has a frame (12), and a flexible blade (14) located integral with the frame to act on a mechanical oscillator at a contact portion (14a) presented by the blade. A reference element adjusts a pre-stress of the flexible blade comprising a pre-stress finger (22), where the element is located integral with the frame. Two correctors are arranged symmetrically relative to a line perpendicular to a path of a support zone of the mechanical oscillator. The frame, the blade and elastically deformable structures form a planar and/or monolithic piece. An independent claim is also included for an escapement mechanism comprising a mechanical oscillator.
