Reloj Ulysse Nardin modelo

A revolutionary timepiece that rotates the Earth in its true geographical shape seen from above the North Pole. A flexible spring bends from the Tropic of Cancer to the Tropic of Capricorn to reveal the part of the Earth lit by the Sun and to indicate the time and place of sunrise and sunset. The moon rotates around the Earth. The dragon hand indicates the eclipses of the sun and the moon. The perpetual calendar completes one turn each year. Case 43 mm in platinum.
