This face is a ground-up rebuild of the Grand Prize Winner of the Samsung world-wide Watchface Design Competition and is now fully interactive - an aviator-style analog chronograph paired with a digital world time watch face
I would change the two sub-clocks (on World Time) to 24-hour, or otherwise indicate day/night-time. See my sub-clock demo, in case it inspires you: Reference design: analog watchface sub-clocks
You should also show the timezone offset(s) (eg. UTC -7), if that will fit.
PS.I’m still working on calendar-logic for 40 (or 200) top cities - for daylight/summer time, etc.
