I watch pair with and 11 pro max phone

Hello bebecho,

Thank you for reaching out to Apple Support Communities.

These steps should help:

"If the pairing process stalls

If it seems like the pairing process has stalled — for example, the pairing animation remains on the screen for several minutes — resetting your Apple Watch might help:

1. Press and hold the Digital Crown while your Apple Watch is in pairing mode.
2. Tap Reset when it appears on your watch.
3. After your watch resets, you can pair again."

More details can be found here: If you can't pair an Apple Watch with your iPhone

If the issue persists, can you provide a few more details? What exactly happens? Which Apple Watch are you using? Also, which watchOS version do you have?

Cheers!
