The Patek Philippe Celestial Rose Gold Diamond Black Dial 44mm Ref. 6104R/001 is a masterful astronomical timepiece that showcases the beauty of the night sky. Its 44mm rose gold case is adorned with 38 baguette-cut diamonds (~4.27 ct) on the bezel and 22 baguette-cut diamonds (~1.13 ct) on the clasp, totaling ~5.4 ct. The black sapphire-crystal dial features a rotating sky chart that displays the configuration of the northern hemisphere's nocturnal sky, including the phases and orbit of the moon. Powered by the self-winding Calibre 240 LU CL C, it offers a 48-hour power reserve and functions such as mean solar time, sky chart, moon phases, and the meridian passage times of Sirius and the moon. Water-resistant to 30 meters, the watch comes on a hand-stitched shiny black alligator leather strap with a rose gold folding clasp. This Celestial is a remarkable fusion of technical precision and celestial artistry.
