Watch, has bezel comprising lower annular radial surface, and external radial flange comprising convex external peripheral surface that is radialy supported against concave internal surface while applying axial vibration to glass

摘要

#CMT# #/CMT# The watch has a case (12) provided with a middle part (14), glass (16) and a display dial (18). The glass comprises an external radial flange (36), and a bezel (20) comprises a lower annular radial surface (44) arranged in an axial support against an upper face (46) of the flange. The flange comprises a convex external peripheral surface (52) that is completely complementary to a concave internal surface (54) arranged under the radial surface of the bezel. The external peripheral surface is radialy supported against the internal surface while applying axial vibration to the glass. #CMT#USE : #/CMT# Watch. #CMT#ADVANTAGE : #/CMT# The bending stresses are reduced, so that risks of cracks are reduced. The glass of the watch has improved impact resistance. The internal tension in glass is minimized. The radial sliding of the flange is stopped before pins come in contact with the middle part, so that the risks of rupture of the glass are reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a peripheral portion of a watch. 12 : Case 14 : Middle part 16 : Glass 18 : Display dial 20 : Bezel 36 : External radial flange 44 : Lower annular radial surface 46 : Upper face of flange 52 : Convex external peripheral surface 54 : Concave internal surface.
