Activating new Apple Watch but stuck on "Unable to Check for Update"

I am trying to activate my new apple watch, but I get stuck on "Unable To Check For Update". I can choose Start Over or Try Again. I've tried both and neither options lead to success. Help please! My phone says "Checking for a software update failed because you are not connected to the Internet." But that is not true. I have tried to activate it using two separate phones and that's not working. We have checked out internet connection, and it is working fine. We are stuck in this loop and cannot get the watch to activate.
