 General Specials: GPS Target Group: Mens Case housing diameter: 45 mm housing height: 12 mm Shape: Round housing color: Silver glass: Sapphire The most robust watch crystals are made out of sapphire glass. Only diamonds and carbide is harder and can scratch sapphire glass. Of course there are other materials such as some metals and stones which will scratch your sapphire glass crystal, so it is not wise to expect the watch to handle any abuse without getting marked. Sapphire has one downside though, it is highly reflective. Some watches receive an anti-glare coating to compensate for this, but sadly this coating is less hard and will scratch more easily. glass Material: Stainless steel
