发明名称 Wristwatch with concave glass lens and dial
摘要 A wristwatch that includes a concave lens and concave dial contained within a bezel and housing. The concave shape of the lens causes the upper most surface of the wristwatch to be the bezel, so the upper surface of the lens cannot be scratch if the user places the watch face down on a surface. The concave shape of the dial causes an increase in surface area for time marking indicia on the dial face. This effect combines with the concave angle of the lens to increase the appearance of the indicia and reduce glare.
