Wrist Gestures doesn't always work and why does the main watchface disappear?

Two very disappointing things. I got the mesh band watch and noticed right off the bat that the watch is very poor at recognizing wrist gestures. It does not show the main watch face unless the wrist is flicked strongly.

Is there any way to keep the main watchface on all the time instead of it being replaced when the watch is not being looked at? What's the point of these fancy watchfaces if they do not stay on?
