Glance is the feature I love a lot on my Nokia as well. The glance screen allows me to look at things like time on my phone without even turning it on.
All you need do is standardize android phones to have a secondary screen on the other side that never turns off or needs to be unlocked, eink or whatever. Then transition that small screen to also display on your wrist.
I suppose they could even support the "small secondary screen" interface on phones without a physical secondary screen, by simply displaying its contents inside the lock screen.
I used to have a foldable phone with a small secondary screen like that as well; it really was nice, and would be even better if it didn't need a button-press to activate (e-ink or whatever), as turning on the screen is always about 80% of the effort when I just want to see the time... [they can't make the button too easy to press after all, to avoid accidental activations...]
