Glass mounting structure for watches

A glass mounting structure comprising a watch case, a bezel, a glass having beveled portions at upper and lower edges thereof, a first packing disposed between said watch case and bezel, and a second packing disposed between said bezel and glass, said watch case having an upper receiving portion, an axially extending inside engaging portion, an annular groove provided in a lower portion of said axially extending inside engaging portion, and a lower receiving portion laterally extending from a lower portion of said annular groove, said bezel having a peripheral engaging portion for engaging said first packing, a lower portion opposite said annular groove, a beveled guiding portion at the lower end of said peripheral engaging portion which is positioned lower than the upper edge of said annular groove, an underside portion laterally extending from the upper end of said engaging portion which overlaps and contacts said upper receiving portion of said watch case, and an inside annular groove for receiving said second packing, the upper boundary of said annular groove for receiving said second packing being spaced from said glass at all times so as not to contact the upper edge beveled portion, the lower boundary of said annular groove for said second packing being extended to the underside of said glass, said bezel being inserted from the upper edge of said first packing thereinto, so that a lower portion of said first packing is expanded into said annular groove of the watch case, whereby when said bezel is removed from said watch case, said first packing is held in said watch case, said glass being downwardly inserted into the second packing, so that a periphery of the glass dents in said second packing and that the upper portion of said second packing presses down on the beveled portion of said upper edge.
