From the Henry Graves Supercomplication to the Calibre 89, Patek Philippe has always pushed the boundaries of what a watch can know. The 5102 G Celestial is the purest expression of that obsession, a real-time astronomical display featuring a sky chart of the northern hemisphere, the phases and orbit of the moon, and the meridian passage of Sirius and the Moon. This watch is from 2005 and comes with a complete full set. A grand complication with a production window so brief, it has become a collector's legend.
