Yes, wake the watch. I have an old Samsung gear, the original one and it doesn't have this feature.
!! That's crazy town. Nowadays, other than the Gear S2 (I'm probably wrong on the name, the newer Taizen Samsung watch), and the AppleWatch, they should almost all be running AndroidWear, maybe check if that's a standard setting?
i thought they all auto turn on when your wrist is up and turned over to look at. no?
I thought that as well. But they also all probably have an auto-sleep-display timer, (at least my AppleWatch does), and if I'm actually watching the second hand, and it takes longer than the timer, I need to tap the screen to wake it back up.
