My watch keeps unpairing when I try to set it up

Hello Ceceg17,

If you tried all the steps in the article you posted from, make sure both devices are updated and have been restarted which can clear out issues with pairing:

1. Update your iPhone or iPad - Apple Support
2. Update your Apple Watch - Apple Support
3. Restart your iPhone - Apple Support
4. Restart Apple Watch - Apple Support

If you still have issues try unpairing the Apple Watch completely yourself then pair it again:

1. Unpair and erase your Apple Watch - Apple Support
2. Set up your Apple Watch - Apple Support

Thanks and have a wonderful day.
