tldr: Apple's upgrade process blows.
I upgraded my phone to IOS 13 this morning. After that, it informed me that my watch had to also be upgraded to watchOS 6 and that it would not work until I did. That really would have nice to have been told *before* moving to IOS 13.
So, before leaving for the day, I was forced to attempt the upgrade to get the watch working. The WatchOS update has failed 3 times. Each upgrade/download said it would take 12 hours (like others have reported) but each *only* took about 90 minutes.
I'm stuck on the third attempt. The phone said to line the watch face up with the view finder in the phone app but the view finder doesn't render. The bottom half of the screen is just black. So I switched to pairing manually.
Pairing manually is failing at the step on the phone "Enter the 6-digit code displayed on your Apple Watch" because no 6 digital code is displayed on the watch. Just the fuzzy silver flower that looks like fireworks.
Other problems in their work flow include being stuck in a loop on the phone between the "Get Connected" screen where it tells you to make sure the phone is connected to wifi or cell and to turn blue tooth on" and the "Start pairing" screen.
I'm sure that if I go to a nearby Apple store, I'll get no time because they're busy selling new phone.
****** process...
Super frustrating....
I guess I'll do what someone else said which is try again "in a few days".
Thanks for listening...
update: called support. We were not able to work through it. Have verified BT working on my phone. Next step is to very BT working on watch by trying to pair with another iPhone.
update: resolved: Been stuck in a state where the watch and phone would not pair via bluetooth. After verifying that my phone's BT worked and that other iphones could also not pair with my watch, I assumed it was an issue with the watch's BT. I restarted the watch several times but that didn't help. I also deleted the watch from Find My iPhone per instructions from Apple Support. That didn't help. Finally, while researching what all my hardware options were with the watch, I came across the instructions for the factory reset. I did this and as soon as it rebooted, the phone could see it and the upgrade process completed normally.
