One of the most accurate celestial watches ever produced, the Patek Philippe Grand Complication Celestial Watch features a unique blue dial that shows the sky as you would see it from Geneva and that has a microscopically accurate star field disc. The watch features novel celestial functions like solar time, sidereal time, lunar days, and lunation. Its hour and minute hands are made of white-lacquered gold while hour markers are luminous sans serif Roman numerals. The case is pure 18K white gold case and features a round bezel set with 38 stunning baguette diamonds. The crocodile leather strap is blue in color and features a strong tang buckle.
