Were you a regular watch-wearer before you got this? The perspective on this watch is interesting. There are people who don't wear watches and look at this the same as they look at their phones and computers. And there are some who wear watches but look at this as more of a computer on their wrist.
It's a watch, man. It's meant to be worn. It's also a computer, and it's meant to be used. It's meant to be enjoyed. I used to be so concerned about this stuff that I bought a space black just because it was claimed to be the most durable watch, then bought applecare, then bought a screen protector. I was in the middle of reapplying the thing for the 6th time, and I had been attempting to apply it perfectly for an hour, before I decided, "This is ridiculous". Threw out the screen protector. Went a long time without scratching it and once the scratch got there, I didn't even notice after a couple of days.
Regular watches still get scratched. As long as they work, no issue. If it gets greasy then clean it. If it gets scratched, does it still work? If so, keep using it. A scratched watch that still works is a watch that is a survivor.
