Left sub-dial shows watch battery level (outer ring) and temperature (F) by default (for those on Celcius, I changed the default to phone battery level to keep the 0-100 scale)

Tap on left sub-dial to scroll through sunset / sunrise times (outer ring) and local 24 hour hand and then your three time zones

Tapping on lower sub-dial toggles labels for the left sub-dial on and off

I pulled together a number of community resources and reworked them in an external vector program for this one
