Abstract
PURPOSE: To cause the interference of light reflected from the surface of glass for a watch and to enhance the transmittance by forming a transparent coating layer of oxide, fluoride or the like of a specified element on the glass surface in a prescribed thickness.
CONSTITUTION: The titled cover is obtd. by forming a transparent coating layer of oxide, sulfide, carbide, nitride or fluoride of an element selected from the II, III and IV group elements, actinoids and lanthanoids, or a mixture thereof in l/2λ, 1/4λ, 3/4λ, λ or 10W1,000Å thickness. This cover has high transmittance and strength, and the dials of the watch can be read easily.
