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.
