The Midnight Planétarium (Midnight Planetarium) -an incredible creation and a real work of art by the most talented jewelers of Van Cleef & Arpels and watchmaker Christiaan van der Klaauw. These exclusive astronomical wristwatches not only show time, but also accurately reflect the motion of the six planets of our solar system around the Sun. Each of the six planets is represented by preciousor a semiprecious stone of the corresponding color. The serpentine is for Mercury, the jadeite for Venus, the turquoise for the Earth, the red jasper for Mars, the blue agate for Jupiter and the rare mineral sugilite for Saturn. The solar core is made of gold. Two other planets Solar system was decidedto exclude from the miniature model, since the length of their orbits would make the movement of the planets on the clock invisible and impractical. Uranus makes a revolution around the Sun for 84 terrestrial years, and Neptune for 164. Not so long ago, Pluto was excluded by astronomers from the list of classical planets of the solar system and referred to dwarf planets, so its presence on the clock was not even considered.Unique astronomical wristwatch consistsof 396 items, including precious stones and metals. On their creation took a little more than three years, so the price of space - 312 000 euros. Whatever it was, for hours you want to admire and admire, contemplating the slow motion of the planets and the flickering of stars.
