Again that wouldn't be as descrete as simply taking a peek at your watch face. It's no biggie as the jailbreak will fix all the issues it will have.
Sure, buddy.... a jailbreak will address the fundamental fact that if the screen stays on all the time, the battery drains more rapidly??
Lol, it's already been pointed out to you that the Watch can be activated by pressing a button. If that is too difficult for you, what is it that you think jailbreakers can come up with that would not involve the motion of lifting it to glance, nor need a button press... beyond having the screen be always on??
I feel like you're describing an impossible feature.
