Just wondering if anyone else has managed to scratch the back of their Apple Watch at all. Was surprised to see a very clear, small scratch on the back of mine. Looked at it using a loupe and it's definitely not just material deposited onto the back of the watch. I can see the light shine in the gouge. Thought it would be more durable. I had heard of others scratching the back with the DLC-coated Milanese bracelet but I don't have that. As I understand it, the ceramic is zirconia dioxide and probably 8.5 or so on the Mohs scale, so it's not completely impervious to scratches. Just wondering if anyone else has managed to do so.
