My crystal is supposed to be scratch-resistant, but it has been scratched. Why?

Our watches are fitted with scratch-resistant sapphire crystal, which withstands normal wear. However, extremely hard materials such as diamonds or aggressive abrasive contact can still cause scratches.

Some models feature an anti-reflective coating applied to the crystal. This thin layer improves legibility but is more susceptible to scratching, which may give the impression that the crystal itself is scratched.
