Easily readable digital watch, with the minutes rotated 90 degrees.  Battery meter at top, date at bottom.

The peg outside the gear represents the current hour in analog clock style.  The dots on the gear are minutes -- grouped in fives and positioned in sort of an analog clock style, so they're easy to read.

In this screenshot the time is 10:09.

Simply shows the current time in the form of tally marks.  It's 9:58 in this screenshot.

Date, time and battery with a splash of color, like a Holi celebration or a Color Run.

Analog watch that shows time in the style of a radar screen.

The circle is divided into 12 segments, representing hours.  The current minutes can be read by the position of the radar blip near the outer edge, and also in the amount of the next segment that is filled in.  In the screenshot below the time is 9:25.

Easy-to-read watchface in the colors of the Nonbinary Gender Pride flag (http://gender.wikia.com/wiki/Pride_Flags).  Shows date, time, battery status and current temperature.

Represents the time as a sine wave, with midnight at the bottom of the curve, noon at the top, and zero crossings at 6AM and 6PM.  Colors switch between day and night settings according to sunrise/sunset times from openweathermap.org.  Also shows date, battery status and current temperature.

A hybrid (analog+digital) watchface with a glitch art/cyberpunk aesthetic. Only updates once per minute to conserve battery life, though constant animation might be awesome... 

The central ring is the hour, outer ring is minutes.  A narrow stripe on the right edge serves as a color-coded battery meter.  The current date is encoded in the text along the top: a single letter for the day of week (suNday, Monday, tUesday, Wednesday, tHursday, Friday, sAturday), the day of the month, the pointer address of the GContext in lowercase, and the month in upper case with the first character shifted.  In these screenshots it's Friday, July 24.

A minimalist analog watchface.  The outer ring represents minutes and the inner rectangle represents hours.  The "hands" simply sweep around and fill in the space like a pie chart.  In the screenshot shown, the time is about 6:47.
