Tested with Watchy 1.4.10
Tools >> Manage Libraries >> Add "Sunset" (tested with 1.1.7)
Arcs, from outside to inside, are Minutes, 24 hours, sunset/sunrise, day of month, month of year.
Labels, clockwise, are battery voltage, timezone offset & year, moon phase, and day of week.
Sunrise & Sunset are dependent on LAT and LON in settings.h. these should be set even if wifi and NTP are not configured.
