Pre-Owned Patek Philippe Grand Complications Celestial Ref. 6102P

Introduced in 2012, exactly ten years after the Celestial ref. 5102, the Patek Philippe Grand Complications ref. 6102P updated the astronomical wristwatch with a cleaner 44 mm platinum case and a pointer date. Its long central date hand reads an outer scale, leaving the celestial display free of an aperture. Three superposed sapphire-crystal disks rotate at different speeds: the blue lower disk follows the Moon's orbital position, while a transparent upper disk bears the sky chart and carries the Milky Way on its reverse. Calibre 240 LU CL C powers the display with a 22K-gold off-center minirotor. Patek Philippe evaluated more than 25 trillion possible transmission-ratio combinations to optimize the astronomical indications, producing a moon-phase deviation of just 6.51 seconds per lunation. The ref. 6102P-001 pairs its blue celestial display with a shiny navy-blue alligator strap and platinum fold-over clasp; a diamond at 6 o'clock identifies the platinum case. Now discontinued, the 6102P remains a technically ambitious evolution of the Celestial, adding useful calendar information without interrupting its defining view of the Geneva night sky. Every watch is authenticated and backed by The 1916 Company's 2-year warranty.
