First release.
A world map on the dial with a real solar terminator across it: the day and night boundary computed from the sun's declination and placed by the clock, equation of time included. Eighteen shapes across the year, a warm line on the boundary and a twilight wash behind it.
A marker on the city your watch's time zone names, breathing so you can find it. 598 zones in the table.
Five complication bays, three map palettes, six type colours, 24 or 12 hours, its own always-on frame.
