How often do we see watches in our shop. that through normal wear and tear have got scratches on the watch glass. Very unsightly and annoying to most ownerrs. Watch glasses come in 3 different materials, 1. Acrylic or plexiglass which is basically a hardened plastic. 2. Mineral glass, the most common type and 3. sapphire crystal, very expensive but also most scratch resistant. At the Watchdoctor you can have your acrylic or mineral glass restored to near new condition. As far as mineral glass restoration is concerned we believe we are the only place in the world that can do it for you. Come by the shop or contact us for more information and remember “When it’s too hard for the rest, come and see the best”
