How to revive an Apple Watch That Will Not Pair After Resetting the Device
For the TLDR Crowd. Yesterday after multiple tries to pair my phone with my watch I hard reset the phone and tried again. When it asked me to login to iCloud I did, and then I was able to pair the phone with the watch.
For the patient crowd, for several days I was unable to pair my Apple Watch SE with my iPhone SE 2nd gen. I tried rebooting and resetting the watch and I had no luck.
