Three sapphire crystal discs are used to simulate the orbit of the moon and the passage of the stars, hence rendering it a remarkable sense of depth. Lab Exercise III: The Position of Constellations in the Sky over a Year The star Question 12 (10 points) Listen Study the sky chart over the year by. The highly sophisticated automatic movement calibre 240 LU CL consists of 301 individual parts, meticulously hand-finished in the workshops of Patek Philippe. To determine the highest possible accurateness for the astronomical displays, the engineers of Patek Philippe researched 25 trillion (25,000,000,000,000) ratio combinations, showing the enormous horological challenge the model represents. A delicate elliptical contour on the inside of the glass frames the portion of the sky visible from all cities sharing the latitude of Geneva. Its brilliant stars are found on the celestial equator and are visible throughout the world, making this constellation universally recognized. Hours and minutes are displayed by two pierced white hands. Orion (IPA: /()rn/), a constellation often referred to as The Hunter, is a prominent constellation, perhaps the best-known and most conspicuous in the sky. The nocturnal sky of the northern hemisphere rotates to show the apparent angular motion of the stars and moon as well as the progression of the phases of the moon.
This astronomical wristwatch borrows the principle of the celestial canopy from the most complicated wristwatch ever produced by Patek Philippe - reference 5002, the Sky Moon Tourbillon. Launched in 2002, the ‘Celestial’ is one of the most important horological complications ever developed.
