The Patek Philippe Ref. 6102P-001 is a remarkable watch that showcases the brand's tradition of creating astronomical timepieces. The Celestial watch's rotating chart on the dial displays the configuration of the stars and phases of the moon in the northern hemisphere. The watch's skeletonized hands indicate the hours and minutes of mean solar time, while an ellipse frames the part of the sky visible from Geneva and other cities at the same latitude.

The self-winding mechanical movement is powered by the caliber 240 LU CL C and also features a date indicator by hand, along with the time of meridian passage of Sirius and the moon. The platinum case has a sapphire crystal case back and is water-resistant to 30 meters, with a diameter of 44mm and a height of 10.58mm. The watch comes with an alligator strap with square scales, hand-stitched, in a shiny navy blue color and a fold-over clasp.
