I have a watch with a sapphire glass face. I must say, I have always been impressed with its scratch resistance. Nothing I have done so far has scratched the glass, and it's coming up on ten years. It's not from babying the watch either, because the stainless steel bezel has developed quite a few marks.
- hippich 14y agoCan confirm it. few watches I had all been with sapphire glass and no scratch since purchase (10-15 years) Only one watches have small blemish after drop of hot metal dropped on it while I was welding exhaust turbo manifold for my car. And even this one is tiny and adds nice touch to my watches :)
- Shenglong 14y agoInterestingly, if you want to know whether something you own is sapphire glass, you can usually conduct a simple experiment: Drop some water onto the glass face, and jostle the item around a bit. If the water stays put in a semi-uniform droplet, regardless of the motion and angle, it's probably sapphire.
- reeses 14y agoSapphire has been used for watch crystals (and increasingly for case backs) for quite a while now. My "precious" digital camera has a sapphire cover on the LCD. It's interesting what they're doing in terms of shapes beyond sheets and simple "lens" type constructions. I made a foolish watch purchase because the sapphire case back was especially compelling. (This isn't my video, but it's the same watch: http://www.youtube.com/watch?v=DxNgAXDDTgo http://www.youtube.com/watch?v=DxNgAXDDTgo) I've wanted a camera lens made of sapphire front and rear elements, but the refraction index would require more custom engineering than it would be worth. Definitely more expensive than a few $10 UV filters. :-)
