This is my own interpretation of the Trekv2 Watchface for Pebble. (https://github.com/mereed/pebbleface-trekv2)
Things that I changed:
- Display both F and C temperatures
- I use 24h display and don't care about colons.
- Remove '24h' label from top corner
- Change date format to: %Y%j %m%d
- Make battery squares have an 'empty' square for squares above current charge level
