Description

  

  Fond de     boîte    de     montre    et procédé- pour sa     fabrication       La présente invention se rapporte à un fond  de boîte de montre et à un procédé pour sa  fabrication.  



  Le fond est caractérisé par le fait que la  face extérieure présente deux parties, à savoir  une zone annulaire située à un niveau différent  de l'autre partie formée par le reste de la face,  ces deux parties présentant un aspect différent.  



  Le procédé est caractérisé par le fait que  l'on polit toute la face du fond, puis mate l'une  des parties en laissant l'autre polie.  



  Le dessin ci-annexé représente, à titre  d'exemple, une forme d'exécution du fond de  boîte selon l'invention.  



  La     fig.    1 en est une vue en plan ; et  la     fig.    2, une coupe par<I>11-1I</I> de la     fig.    1.  Le fond représenté comprend, sur sa face  extérieure, un bord mat 1, une zone annulaire  polie 2, et un centre mat 3 ; la zone 2 annulaire  est surélevée par rapport aux deux surfaces 1  et 3 qui l'entourent et est polie, alors que 1 et  3 sont mates.    Pour l'obtention de ce fond, on commen  cera par en polir toute la     surface,    après quoi  on recouvrira la zone 2 d'une matière protec  trice et l'on procédera au matage des deux sur  faces 1 et 3 l'entourant. Ensuite, la matière  protectrice sera enlevée.  



  Le fond pourrait, bien entendu, présenter  une zone annulaire en retrait par rapport aux  parties l'entourant ; dans ce cas, c'est cette zone  qui sera matée.



  The present invention relates to a watch case back and to a process for its manufacture.



  The bottom is characterized by the fact that the outer face has two parts, namely an annular zone located at a different level from the other part formed by the rest of the face, these two parts having a different appearance.



  The process is characterized by the fact that we polish the entire face of the base, then matt one of the parts while leaving the other polished.



  The appended drawing represents, by way of example, an embodiment of the case back according to the invention.



  Fig. 1 is a plan view; and fig. 2, a section through <I> 11-1I </I> of FIG. 1. The base shown comprises, on its outer face, a mat edge 1, a polished annular zone 2, and a mat center 3; the annular zone 2 is raised with respect to the two surfaces 1 and 3 which surround it and is polished, while 1 and 3 are matt. To obtain this base, we will begin by polishing the entire surface, after which we will cover zone 2 with a protective material and we will proceed to matting the two surfaces 1 and 3 surrounding it. Then the protective material will be removed.



  The bottom could, of course, have an annular zone set back with respect to the parts surrounding it; in this case, it is this area that will be put down.
