Wife and I wanted to sleep in on a sunday after having a late night. The watch decided I needed to wake up at 5 AM since that is when I normally wake up during the week and started buzzing and vibrating every 20 minutes. Woke both of us up. I never asked for this. I didn't feel like diving into how to turn it off at 5AM so I took the watch off and dropped a 40 pound dumbbell on it. That stopped it.
I wanted a watch to track my health, not a watch that tries to wake me up because it's algorithm decided it needed to wake up. I need a more dumb watch now
