I am challenging myself to keep my new 44 SS scratch-free (even from micro-scratches). I'm pretty good at not banging my watches on to surfaces and I'll see where this goes. As I have learned from the 2 days I've been wearing and cleaning mine, the surface is not prone to scratching very easily as I suspected. I've worn the watch with all sorts of jackets with different material, cleaned it gently with a microfibre cloth several times and I still do not see any micro-scratches even under heavy lighting like the iPhone X flash light or under the sun. I've always wondered if the stainless steel Apple is using this time is tougher. Although not a mention in their own description of the watch, I'm starting to believe it's a more durable material than the ones before it. Is there a thin outer layer on it that'll eventually go and reveal the actual SS inside or not? Only time will tell and I will update my findings.
