Updating OS bricked my Series 3
Warning to others out there. I updated my iPhone to 14.0.1 and then went to update my watch OS. The update downloaded and then would not install, telling me installation would resume when I was connected to WiFi. I was already connect to WiFi, so I cancelled the installation and started again. Same issue, started again. It downloaded and was then stuck on verifying for hours. I powered down the phone and reset my watch. Restarted installation again and was stuck on verifying overnight.
I did a Google search and saw that some people had success pairing with an iPhone still on iOS 13. I tried pairing with my work phone which has not been updated - and it says I need to update my phone to pair the watch!
I turned my phone and watch off again. Now my watch is stuck in a reboot mode where the logo comes on and off but nothing ever loads. Apple chat support was no help so I have to wait until Tuesday to get in with the Genius Bar. Last time I had a Genius Bar appointment, the technician locked me out of my Apple ID 🙃.
Beware the watchOS update!

I had the same issue with my Series 4, and I solved it by resetting the watch to factory settings and the repairing it with my updated iPhone. I was then able to complete the update.
