Abstract (en)

[origin: EP2090941A1] The oscillator has an oscillatory system constituted of a balance (1) and a return spring (3). A frequency correction device (20) has flexible elastic straps (9, 10) that are supported on a T-shaped connection member or stop (8). The straps have ends connected to a fixation and adjusting interface (11) via pins (12, 13) using locking screws (15, 16), respectively. The interface is secured to a frame (4) by a screw (17), and the member or stop is directly fixed to the balance. The member or stop is pressed against free ends of the straps during a part of oscillation period.
