PROBLEM TO BE SOLVED: To solve problems of a conventional wrist watch with a magnifying lens wherein it is difficult to attach the magnifying lens and only flat glass can be stuck considering the protection of the glass plane, while the model of the specific kind can only be selected when the wrist watch is intended to be changed to another model. SOLUTION: By providing a hemispherical (cycloid) transparent suction cup having a convex lens action, the dial plate is enlarged, the material of soft plastic resin is thickened, and the glass plane can be protected. Thus, a person difficult to read the dial plate, a person intending to improve the visibility of a wrist watch of fine scale such as chronograph, or the like can instantly use a suction cup by selecting the suction cup matching with the diameter of the glass plane. By increasing the thickness, the glass plane can be protected from the impact of a hard matter such as a desk or door. COPYRIGHT: (C)2007,JPO&INPIT |
