<p>The collet (1) has a junction point (8) with an inner end of a hairspring (2), and a lateral recess (10) provided on a zone (7a) of the junction point, where the zone is a junction zone between elastic deformable arms (3). The recess is conformed so that the distance (R) between the junction point and a center (O) of a balance staff (6) is not modified during driving of the collet on the balance staff, where the collet has triangular shape. Independent claims are also included for the following: (1) a hairspring-collet assembly (2) a method for designing a collet of a clock (3) a method for forming a collet.</p> |
