This amazing clock is called the Planetarium-Tellurium. Made by Richard Mille over a 7-year period, it has a perpetual calendar that shows not only the Earthâ€™s position, but also that of Venus, Mercury, Sun and Moon.
It even shows the rotation of the earth on its axis, the phases of the moon, and the Zodia signs. The materials used in its construction include titanium, steel, brass, gold, silver, and red corundum.
All kidding aside, very cool!
