Awwww man! I just noticed a big fat scratch on the sapphire screen of my Apple Watch. How is this even possible? I thought sapphire is (nearly) unscratchable?! I can't feel any unevenness while touching it with my fingernail. It when I move the watch around, the "scratch" shimmers kind of silver... Not even my steel case has any noticeable scratches, I can't complain it to my self how this should have happened ... What do you think?
