The reason why a watch with a sapphire mirror surface is blue is that its surface is coated with a blue protective film ( Often referred to as AR coating crystal glass), the sapphire mirror itself is colorless and transparent.Some high luxury brands of 316L stianless steel quartz watch, handwinding wrsit watch, semi-precious stone watch and other watch types will basically choose sapphire glass as the first choice.
