<p>The spring (37) has a hairspring (41) whose inner coil has a collet (40) arranged on a mounting structure (32). Another hairspring (43) is connected to the outer coil of the hairspring (41). An inner coil of the hairspring (43) has a device (47) for shifting the pinning point comprising a free end arranged to be secured to a balance spring stud in the plane of hairspring (43). The shifting device has a structure (42) connected to the inner coil through an u-shaped bend extending from the inner coil of the hairspring (43) to avoid providing elastic torque. An independent claim is included for movement structure.</p> |
