My crystal is supposed to be scratch-resistant, but it has been scratched, why?
TAG Heuer watches from the current collection are fitted with a scratch-resistant sapphire crystal that is not affected by general wear and tear, but extremely hard material like diamond and intense rough treatment may scratch it. Some models are coated with an anti-reflective substance, a thin layer on the crystal, which eliminates reflected light, ensuring optimum readability. This coating is susceptible to scratches and can therefore give the impression that the crystal is scratched.
