Those UI elements are way too small for the watch. I have the big one (my girlfriend has the smaller one) and even on mine they would be unreadable.
There's a reason all the native apps use 3x larger type than that. Also, touch targets need to be about a third of the screen at minimum to be useful. It's already really hard to type in the unlock passcode accurately and that is a 4x3 grid. That hamburger button in the corner would be unusable. :/
