Ulysse Nardin, Le Locle, Suisse, N° 290, Planetarium Copernicus, Ref. 801-22, 1990's. Extremely fine and rare, astronomic, self-winding, 18K yellow and white gold prototype of a gentleman's wristwatch with perpetual calendar (analogical representation of the Copernicus solar system), leather strap and 18K yellow gold Ulysse Nardin buckle.

C. three-body, massive, polished, transparent back, bezel graduated with engraved Roman numerals, white gold hooded lugs with the signature, yellow gold screwed bars. D. bi-colour gold and blue. The "movements" of the Copernican planetarium system are visualized in real time and reconstructed with incredible precision: the rotation of planets around the Sun, of the Moon around the Earth with moon phases, the elapsing time of months and constellations that follow one another on the Earth- Sun axis. At the center is the Sun, the third fixed ring is the Earth, a small gilt globe with the Moon rotates around it, the other five are the Planets known during the Copernican era: Mercury, Venus, Mars, Jupiter and Saturn. The gilt more external ring is the equator, with the indication of months and constellations, that completes a turn in a year. To facilitate the reading of the Planetarium, the glass has 12 lines internally silkscreened that, starting from the Earth, creates a spider web design, defining the position of the planets in relation to the zodiac signs. "Baton" tritium hands. M. 13"' hand engraved, 33 jewels, lever escapement, monometallic balance, shock-absorber, self= compensating flat balance-spring, 18K white gold skeleton and engraved rotor with bi-directional winding. Signed on the case, numbered on the movement. Diam. 40 mm.
