wtb-db is a stats heavy watch face with heart rate tracking, distance traveled, calories burned and steps taken stats. Also displays the date on the left and battery percent on the right. The app colors are fully customizable with 24 colors to choose from for both background and foreground. If your watch is on 12 hour format it displays "am" or "pm" on the center of the screen and doesn't otherwise. This app also has limited language support.
