Might as well since it can't hurt. Also if you are under 14 days you can just return it and get a replacement if available. Do you have an Apple Store near you in Romania and do they have in stock?...Should I try to reset and pair it again?
My Apple Watch started to randomly go to low power mode (green clock) for no reason, first time at 70% then at 55% and now at 35%. It's running on WatchOS 3.1. Should I go to the Apple Store? Or what other things can I try?
Sounds like it's hardware related. I would fully charge it first, then attempt a re-pair. If it does it again, I would seek a replacement.
That is not possible since it was not released until September 16. You must have a S0 (original).I bought it in August from an Apple Store in the US.....
