Abstract

A method and device for fixing a watch-balance spring to its collet, comprising positioning a balance spring around a collet and pressing the coiled spring in radial direction against a part of the collet for uniformly engaging a part of the inner coil of the balance-spring against a surface of the collet, and, while radial pressure is still maintained, welding by laser the balance spring and collet together.
