Re: Non-reflective coating on sapphire crystals

In Response To: Non-reflective coating on sapphire crystals ()

As I understand it, Omega crystals have anti-reflective coating on the INSIDE of the crystal only. Some other watches have the coating on the inside and the outside, which makes the crystal virtually disappear, but the coating on the outside is scratchable (although the sapphire beneath is not).

The tradeoff for the way Omega does it is that although you can use it your watch as a mirror in the right light, you can also give it a quick buff with the tail of your shirt whenever you feel like it without worrying about leaving any marks on the surface!
