A Clock for the Truly Geocentric

Ulysses Nardin's Planet Earth clock is a jaw-dropping timepiece.

The outer transparent, crystal globe represents Earth, bearing outlines of the continents and oceans. The inner sphere shows at all times the exact position of Sun, Moon and fixed stars in relation to any location on Earth. So it's not really a whole universe, but you get the idea. Rotating at the speed of a real day, one revolution takes 23 hours, 56 minutes and 4 seconds. Separate Sun and Moon hands rotate once in 24 hours indicating which parts of the Earth is illuminated by each celestial body. Finally, a DRAGON hand moves with the signs of the zodiac.

A standard clock on the front panel of the mahogany case indicates the hours and minutes. The Earth clock comes in a limited edition of 99 pieces. LINK
