Thanks for participating in the Apple Support Communities, maghar.
From your post we understand that you're having trouble pairing your Apple Watch with your iPhone, so we'd like to see how we can help. It appears that you've reviewed If you can't pair an Apple Watch with your iPhone. What happens when you go over the steps in the article? If you get an error message, what does it say?
The more information you can provide on the issue you've come across the better.
Cheers.
