Abstract

The collet is obtained by deforming a crown-shaped piece and is in contact for short spaces (3), (4), (5) with the balance staff (1), thus enabling referencing to be carried out by acting on the protuberances (6), (7), (8) with the aid of an appropriate tool. The hairspring (9) is fixed to one of the protuberances (6). <IMAGE>
