Apple

So I got an Apple Watch yesterday, and when I was setting it up it said something about needing an update. So I plugged it into the charger and went to my room, I checked my Apple Watch progress on the app and I thought everything was ok. It then went to a screen like the one shown above, but it was slowly going around in a circle to show the progress. I went to bed thinking nothing of it and the next day my Apple Watch is like this and I can’t pair it. I went to the app and stopped the update process because I waited like 5 min for something to happen on the app but nothing ended up happening. So I stopped the update and tried to re-pair the Apple Watch. It says the Apple Watch is paired to another phone but it clearly isn’t. I went to the website recommended and it said that everything had to be done either on the app or something else on the actual watch. If there are any solutions, please help.
