Why won’t my watch pair to my iPhone 14?

See this support article about how to move a watch to a new iPhone --> How to pair your Apple Watch with a new iPhone - Apple Support

If you no longer have your old iPhone, see the section on "If you don't have your old iPhone."

With absolutely no information about the watch you own we couldn't possibly know why it doesn't pair?

Is this a new watch? A used watch? One you've owned and need to now pair with a new iPhone. What model watch is it?

The more information you provide, the better able we would be to help you.

OK, that's a Series 6 watch. But you didn't answer any of the other questions.
