I have owned a Sport model since last February. At first I was really anal about it and didn't have any blemishes. I finally decided that it's a watch, while I don't want to use and abuse it with normal use there will be some scratches. I have a few micro scratches but they're hardly noticeable, plus it's a watch! Watches get scratched so I'm to going to worry about it.
I Like to consider myself a fairly cautious person, but you're right, watches are inevitable that they will receive scratches. I love my Apple Watch, but even my stainless model scratches fairly easily. But it gives the watch character. So I agree with you.
