This makes me wonder if they can’t fix it via firmware. I’m getting so tired of it, but absolutely refuse to reward their incompetence by buying a new watch.
Mine was doing the same thing. They told me that mine was out of warranty this was after I was on my second watch. I had one and it did this under the 1 year warranty. I then got a new series 3 because they claimed it was broken. Well 12 + months later and the replacement watch is doing the same thing. I worked with multiple people on Apple support, even a SENIOR Advisor who told me well your watch motherboard is probably broken so send it in and we will fix it for $250 charge. Well my watch isn't even worth that. Soooo I contemplated what to do. I ended up getting a new Series 6 and did like they told me to. Backed up my phone, completely reinstalled the whole OS via computer. No apps no nothing. Setup the new Series 6 to it so everything is brand new with no apps to mess things up. 15 hours later. . . . my new Series 6 after being home for less then 4 days is doing it now too. Apple said well your new watch is broken and since its under the 14 days bring it back and they will replace it. . . . Going to do that in the next day or two but I don't think its the watch. Maybe they will tell me next to get a new phone. . . .
