It's huge. Not in a good way.my Asus Zenwatch has an AMOLED screen and is able to have "always on" time. I believe it shifts the "always on" watch faces by a few pixels every now and then to avoid burn in. It's also a simplified watch face when the watch is idle and then shows the full face when you move your wrist to look at it. I do wish my Apple Watch had always on, at least just a simple digital face with hours/minutes.
