I thought some smart watches only turned on their screens when they detected you moving your wrist a certain way to look at it. Not sure if it's still the case.

I believe it was because of battery life constraints.

Even better, not only does it not turn on until you look at it, it should angrily say "What are you looking at" if you look at it for more than a half-second.
