<p>The hairspring has a plane central part (10) extended from an interior point (11) to an exterior point (12), and a movable attaching unit (13) maintaining concentric spires of the part, during oscillations of the hairspring in a timepiece movement. The unit has flexible terminating peripheral curves (14, 15), e.g. blade or blade portion, located in a plane of the central part. The curves are separately extended from the exterior point to end points (16, 17), respectively, where the end points e.g. attachment points, are fixed to a frame. An independent claim is also included for a timepiece movement comprising a frame.</p> |
