Description

       

   <Desc/Clms Page number 1> 
 Pièce d'horlogerie L'objet de la présente    invention   est une pièce d'horlogerie dont la glace est serrée entre un rebord intérieur du corps de boite et une bague extérieure, bague autour de laquelle peut    tourner   une lunette à ressort de friction. Cette pièce est caractérisée par le fait que ce ressort, en forme de    couronne,   est disposé dans l'espace compris entre la paroi latérale extérieure de la glace et la paroi latérale    intérieure   de la lunette appuie, par son bord extérieur, contre un épaulement de cette dernière paroi, et repose, par son bord intérieur, sur ladite bague. 



  Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention, constituée par une montre-bracelet. 



  Celle-ci est représentée en    fig.   1 par une coupe axiale partielle ; la    fig.   2 en montrant un détail. 



  Elle comprend une boîte formée d'une carrure l , d'un fond 2, d'une glace 3 et renfermant le mouvement A. 



  4 est une saillie annulaire de la carrure sur laquelle est engagée la glace 3 serrée contre la    saillie   4 par une bague 5 chassée sur le pourtour extérieur de la glace. 6 est une lunette rotative portant un cadran 7 muni de signes horaires et reliée à la carrure par un cran 8. 9 est un ressort en forme de couronne plate, montré séparément à petite échelle en    fig.   2, qui est logé dans l'espace annulaire compris entre la paroi latérale extérieure 3a de la glace 3 et la paroi latérale intérieure 6a de la lunette 6.    1l   repose, par son bord intérieur 9a, sur la bague 5 et appuie, par son bord extérieur 9b, contre un épaulement 6b de la lunette.    II   se monte facilement et sa    forme   spéciale lui permet de produire un effort maximum sous un volume réduit ;

   en outre,    il   est plan, donc de fabrication simple.

 Timepiece The object of the present invention is a timepiece the crystal of which is clamped between an inner rim of the case body and an outer ring, which ring around which a friction spring bezel can rotate. This part is characterized by the fact that this spring, in the form of a crown, is arranged in the space between the outer side wall of the crystal and the inner side wall of the bezel, with its outer edge, rests against a shoulder of the latter wall, and rests, by its inner edge, on said ring.



  The accompanying drawing shows, by way of example, an embodiment of the object of the present invention, constituted by a wristwatch.



  This is shown in fig. 1 by a partial axial section; fig. 2 showing a detail.



  It comprises a case formed by a caseband 1, a back 2, a crystal 3 and containing the movement A.



  4 is an annular projection of the caseband on which the crystal 3 is engaged, clamped against the projection 4 by a ring 5 driven out on the outer periphery of the crystal. 6 is a rotating bezel bearing a dial 7 provided with hour signs and connected to the middle part by a notch 8. 9 is a spring in the form of a flat crown, shown separately on a small scale in FIG. 2, which is housed in the annular space between the outer side wall 3a of the glass 3 and the inner side wall 6a of the bezel 6.1l rests, by its inner edge 9a, on the ring 5 and presses, by its outer edge 9b, against a shoulder 6b of the bezel. It is easy to assemble and its special shape allows it to produce maximum effort in a reduced volume;

   moreover, it is flat and therefore simple to manufacture.
