Look at my watch after feeling a whole lot of haptics as usual because I can't press the buttons while switching bands. It said EMERGENCY SERVICES and the end call button. I have never accidentally gone so far before, and I didn't know if it actually went through, so I pushed End call. Then I received a phone call 3 seconds later, and it was my local city 911. I strongly replied that it was an accident with my Apple watch and they spoke well.
I don't switch bands often, so I don't really have a good method to do that. I'll just start beating it off and my band change will conveniently, accidentally turn it on again, and I'll finish switching when it's booted! Lol. Feel free to fry me and my incompetence lol.
