I love this topic. Bear in mind that I wasn't a watch guy before the Apple Watch.
I had two Stainless Steel watches, the S5 and S6, and when I discovered scratches and dings on those, I was devastated. My beautiful, pristine watch was now ruined! I found that you could polish them out on the SS models, so I did that, but after some more reading on the internet, I found that scratches on ALL watches of all prices and levels of prestige are normal and that's just how it goes. It helped me relax a lot and let it go.
I still have my SS S6, but I also have an Ultra 2, and some bright light this weekend revealed that I have some scratches on the bezel around the screen, but none still on the screen and the rest of the body. It bugged me at first, but then I just let it go. It's a watch, it's not priceless art. You wear it, it's gonna get dinged.
