My Apple Watch is stuck at the Apple logo

hello everyone!

I bought new Apple Watch series 5 and I have a problem with turning it on.

I wanted to set it up. I pair it with my phone and I put him to install all apps.

And I am stuck with  (apple logo); and it WON'T restart, I tried hard reset...I charge it up...

I am still stuck....

please help :) :/
