European Watch Clock and Jewellery Fair 1989 BF 203
The “Planetarium” by Ulysse Nardin combines with a pure stroke of genius the geocentric universe with the Earth at the centre of our solar system with the true astronomic heliocentric system with the Sun at its centre. The classic planets rotate around the Sun at their correct speed. The Moon rotates around the Earth. All planet cycles are synchronized. Driven by an ingenious automatic movement which can be reset to any given date, the “Planetarium” indicates : astronomical position of the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn; astrological position of the Sun, Moon and planets: ruling sign of the zodiac; moon phases; month; date and exact time. Individually numbered, handmade, 18K gold case, water-resistant to 30 m. (ULYSSE MARDIN “Planetarium Copernicus”)
