Patek Philippe Grand Complications 6300

Patek Philippe Grand Complications 6300GR-001 is a GMT watch with a case measuring 47.7 mm across in white gold and rose gold. The case stands 16.07 mm thick and carries a hand-guilloché hobnail pattern on both faces, reversible so either dial can be worn showing. The manual-winding calibre GS AL 36-750 QIS FUS IRM drives the watch, visible through the sapphire crystal case back. The brown guilloché dial combines a perpetual calendar with moon phase and power reserve display, and a minute repeater and alarm add further chiming functions. The watch sits on a patinated dark chestnut alligator leather strap fastened with a folding clasp. Patek Philippe notes the case is humidity and dust protected only, with no water resistance rating.
