Wow. Had a scary moment with my Urbane today. I've still been having intermittent issues with not getting notified on the watch even though everything says it's connected.
I rebooted the watch today when toggling the connection on and off didn't seem to fix it. After that, it kept shutting itself off. 3-4 times, I looked down at my wrist and the screen was off. The first time or two, I thought, "No big deal. Somehow, I accidentally put it into theater mode." Nope. Off. Hold down the side button to turn it on and watch it start booting. Look down again a little later and the screen is off.
It seems to be up and running properly now, but that was really weird. First bit of real trouble I've had with the watch aside from those wonky connection issues...
