Agreed - leave it
I'm assuming this watch was recently purchased new - you didn't specify. If that's the case, I would agree with John that it's wisest to leave it alone for now. If nothing else, Omega's stated spec on their webpage for non-COSC movements is -1/+10 so you're only barely out of spec. Not only is there a chance that it might "settle" with continued wear, but fixing what ain't broke could introduce further pitfalls of over-adjustment as John alluded to. And if nothing else, you'll be without your new watch for weeks while it's given a very minor adjustment of minimal benefit or potentially even harm, as it could lead to caseback scratches, dust in the movement/case etc. Not worth the risk & headache for a minimal improvement IMHO.
You're probably better off experimenting with varying the overnight resting position, as movements will perform differently in different positions. I'd recommend starting with leaving it crown up overnight based on the wear habits you describe, though you might have to experiment. Oftentimes you can find an overnight position that will "bleed off" some of the error to a more accurate daily overall average rate without regulating.
If in a few months it's still not performing to your expectations and the gain is consistent, *then* it's time to consider regulation under warranty. Just keep an eye on it and enjoy your watch in the meantime.

that's too fast, but I'd let it settle in before having it regulated :)
Too fast

did you even read the very long post I put together on the subject directly below?
