Abstract

Balancier composite (100) pour système oscillant (200) de montre comprenant:- un balancier (1) formé dans un premier matériau ayant un premier coefficient de dilatation thermique et comprenant:● une portion centrale, ● au moins deux ailes comprenant chacune une portion radiale s’étendant radialement depuis la portion centrale et une portion distale libre (1.5),- une lame de balancier (5) formée dans un deuxième matériau ayant un deuxième coefficient de dilatation thermique différent du premier coefficient de dilatation thermique, caractérisé en ce que le balancier composite (100) comprend en outre:- des moyens de fixation (6), tels que des vis, et en ce que la lame de balancier (5) est fixée à chacune des portions distales libres par les moyens de fixation (6), de sorte à provoquer un pivotement des portions distales libres lors d’une variation de température.
