I don't really know how they are going to make it perfect though with current battery tech. I mean apple CAN go a long way by giving more screen time options, definitely. but what watch wearers basically want is "nearly almost always on" which either requires eInk and all the massive compromises that come with that, or will eat through modern battery tech like no tomorrow. not sure how the modern smart watches will be able to handle that while providing true "on demand' time viewing.
Android wear can mostly do a day with an always on, slightly dimmed screen (OLED at least). My guess is apple have too small a battery or the rest of their system is too battery hungry - heart rate checking every 10 minutes could be one culprit. OLED with mostly dark themes should not be a big battery hog. I'd be fine with it not updating all the time too - android wear goes into a dimmed mode that I think updates once a minute and the second hand disappears.
For now though I think tapping the screen to wake will be an ok workaround for those that like glancing down at their watch rather than swinging their wrist up.
If Apple used an OLED display, it wouldn't be hard to show the time constantly on Apple Watch 2 next year.
The burn-in from doing that would be horrifying though.
Which is probably why Apple didn't do that with Apple Watch 1 come to think of it.
The problem isn't current battery tech, it's current display tech.
Android wear cycles the watch face in an orbit of a few pixels to try and mitigate burn in.
