If you mean an Apple Watch 3, or other Apple Watch, see this: https://support.apple.com/guide/watch/set-up-and-pair-your-apple-watch-with-iphone-apdde4d6f98e/watchos#:~:text=Turn%20on%2C%20pair%2C%20and%20set%20up%20your%20Apple,Tap%20Set%20Up%20for%20Myself.%20More%20items...%20
If you meant something else, I have no idea what you're referring to... There is no such thing as an "Apple air 3".
