I'd go for the Ulysse Nardin Tellurium Johannes Kepler watch:
The flexible bar spring rotates around the map in the middle, bending with the time of year, and indicates time of sunset, sunrise and area of daylight (in the Northern Hemisphere - the map is the Earth seen from above the north pole.)
The lunar symbol displays the phase and position of the moon. The dragon head and tail indicate eclipses of the sun and moon, respectively. The perpetual calendar ring rotates to display the date, month and current zodiac sign below the "12 o'clock" position. Completely mechanical and self winding (UN-87 workings) and it's water resistant to 30 meters
