Thanks for the warning. I bought the extended warranty but need to check that I'm still covered in case of any disasters. The last time I did an update of my watch OS I thought it had bricked. It seemed to stall out and took forever. I just left it alone. It seemed to finish but the watch wouldn't turn back on and there was all kinds of crazy behavior like it was having the equivalent of a nervous breakdown before it suddenly normalized.My "Series 0" got bricked and Apple is being difficult about doing anything about it because its out of warranty.
Edit: Mobile wanted to post the whole article, fixed it.
I've had my watch try to imitate a brick before for no apparent reason when putting it on first thing in the morning after a night on the charger. I never figured out what was going on with it because it would eventually turn back on and run fine like nothing had happened.
Good luck to you and everyone who needs service.
