Abstract

The bezel (5) of the glass, formed by a cover for protecting the calibre (3), and which is made from sintered material, is assembled to the said calibre by an inside ring (9) made of vulcanised rubber or injected plastic produced in situ and having two outside projections (9a) and (9b) engaged behind inside shoulders (5a) of the bezel (5) and (3b) of the calibre (3), respectively. The ring (9) furthermore has an outside projection (9c) interposed between the calibre (3) and the bezel (5) and which provides for the waterproofing between these two elements. <IMAGE>
