Here is my first watch face in the app store.

This is a simple face that shows:
Time - with seconds turning on when you turn your wrist (of course)
Date and day
A progress bar for your daily step count as well as numeric steps taken and step goal
A color changing move bar changing from green to red as you sit for too long
A color changing battery gauge with a numeric label
An indicator showing when your phone is connected
