This is really looking nice, I have to say.
imf5tt You don't have someone around with a diamond tester by any chance ? If you are curious about your case, they are quite cheap ...
While I was searching for this watch, I saw a video in which the guy tested both front and back as well as the sides with gem tester and there are no signs of any sapphire whatsoever. EUR claims that this is a composite material like sapphire but my dealer "told" me that it's "glass". I think it's more like plastic than glass, perhaps my dealer meant *perspex glass*, which is a form of organic plastic
