 Balancier    pour   pièce d'horlogerie L'objet de la présente invention est un balancier pour pièce d'horlogerie, comprenant une serge supportée par un bras    diamétral.   Ce balancier est caractérisé par le fait que ce bras présente des    ouvertures   destinées à alléger la partie centrale du balancier. Le dessin ci-annexé représente, à titre d'exemple, deux    formes   d'exécution de l'objet de la présente invention. Chacune des    fig.   1 et 2 du dessin montre, en plan, l'une de ces formes d'exécution. Le balancier représenté en    fig.   1 comprend une serge 1 supportée par un bras diamétral 2.

   Dans celui-ci, sont pratiquées deux ouvertures 3, de forme générale trapézoïdale, et qui sont destinées à alléger la    partie   centrale du balancier. La serge 1 est représentée continue et munie de vis de réglage, mais bien entendu, elle pourrait être sans vis ou coupée. 



  Dans la forme d'exécution de la    fig.   2, le bras diamétral 2 présente deux ouvertures 4 qui sont circulaires.

 Balance for a timepiece The object of the present invention is a balance for a timepiece, comprising a rim supported by a diametral arm. This balance is characterized by the fact that this arm has openings intended to lighten the central part of the balance. The appended drawing represents, by way of example, two embodiments of the object of the present invention. Each of fig. 1 and 2 of the drawing shows, in plan, one of these embodiments. The balance shown in fig. 1 comprises a serge 1 supported by a diametral arm 2.

   In this, two openings 3 are formed, of generally trapezoidal shape, and which are intended to lighten the central part of the balance. The rim 1 is shown continuous and fitted with adjusting screws, but of course it could be screwless or cut.



  In the embodiment of FIG. 2, the diametral arm 2 has two openings 4 which are circular.
