Abstract

PURPOSE:To improve the designing freedom by laser welding of a glass rim with the body made as separate parts from a designing standpoint in the watch casting. CONSTITUTION:In the casting of a non-waterproof watch, a laser beam 12 is irradiated on the boundary of the body 3 and a glass rim 1 to join them. In this case, water proofing unable in the canventional art is made possible and the width 13 of the glass rim 1 can be reduced to less than one-half that 4 in the past, thereby increasing the designing freedom substantially. Besides, the heat of the laser is transmitted locally only, and a gas shielding can eliminate cloud and discoloration of finished surfaces 10 and 11.
