Just a watch face designed to consume minimal power to have in your locker for emergencies. Such as if you go on a long weekend and forget your charger.
The watch face only updates once an HOUR, therefore only shows the hour. However, if your flick your wrist (like when you activate the back light), the full time including minutes is shown for 30 seconds.
The battery indicator is only updated when the screen is updated (once an hour).
Battery is preserved by only using a small part of the screen and updating infrequently.
