Abstract
The glass (1) of the wrist-watch casing carries the ornamental pieces of the casing visible face surrounding the watch dial (17). These pieces comprise a frame (2) of precious or semi-precious material or a very thin metallized layer (31) deposited under the glass (1). The frame (2) is glued in an indissoluble and resistant manner under glass (1) and a spacing frame (3) is similarly glued under frame (2). The collar (6) of tapped sockets (5) is caught and glued in lodgings (7) provided in the face of frame (3) which is glued to frame (2). The unit composed of these pieces (2, 3, 5) and the glass (1) are removably secured to the caseband (8) by means of screws (9) crossing the caseband and engaging sockets (5) fitting borings (19) of the caseband. Under the metallized layer (31) a single spacing frame (25) of base metal is necessary and sockets (5) are welded in lodgings (26) of that frame.
