one thing to keep in mind is that the SS still can scratch. I had a SS Black series 3 that scratched on me. first time, since I had SS series 2 that this never happened to. went to apple and they promised to get it fixed, even though it was cosmetic.. but the apple repair center sent it back without fixing it. But since the store promised to fix it, they did a one for one swap right there and gave me a NIB replacement which was fantastic.
I think that Apple needs more Saffire in the display for it to hold up better. they have done watch tests before and other watches that have Saffire displays have a higher stone rating than the Apple watch does.
apple did me a solid when they didn't have to and I will always be grateful for the high end service. just the moral is that even the SS can scratch.
