<p>#CMT# #/CMT# The method involves snap fitting a watch bezel (1) on a crystal (2), where the bezel includes a snap fit unit that is guided by a guide unit (5) installed on a case (3). The snap fit unit is located against the crystal by the guide unit. The crystal is secured to the case. Axial positioning of the crystal relative to the bezel is ensured by axial positioning unit arranged on an internal face of the bezel and a top face (213) of peripheral edge of the bezel. A snap fit surface of the snap fit unit is formed underneath a snap fit surface of the crystal located on peripheral edge of the crystal. #CMT# : #/CMT# An independent claim is also included for a device for securing a watch bezel, comprising an axial positioning unit. #CMT#USE : #/CMT# Method for securing a watch bezel on a crystal. #CMT#ADVANTAGE : #/CMT# The method enables securing of the bezel to the crystal when the crystal is kept stationary, so that the assembly the parts required for securing the bezel can be facilitated easily, thus reducing manufacturing cost and implementation time, and improving increasing work output and production efficiency. The method enables improving of robustness while holding of the bezel with vertical play. The method enables axial positioning of the bezel relative to the crystal, so that the flanges cooperate with inner annular flange of the bezel to limit radial travel of the bezel during snap fitting and lateral play after the snap fitting, thus providing improved robustness. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a bezel, a crystal and a case. 1 : Watch bezel 2 : Crystal 3 : Case 5 : Guide unit 213 : Top face.</p> |
