Abstract

Method of fixing the outside end (2) of a hairspring to a peg (3). The peg (3) has a flat surface (8) arranged orthogonally to an imaginary plane tangential to the end (2) of the hairspring at the point of contact. This flat surface may consist of one of the faces of a tab (10) provided at the end of the peg, the other face receiving the impact of the laser beam used to weld the end of the hairspring to the peg. <IMAGE>
