The Patek Philippe Grandmaster Chime Ref. 6300/401G-001 is a masterpiece that seamlessly blends haute horlogerie with haute joaillerie. Crafted in 18K white gold, this timepiece is adorned with 118 baguette-cut blue sapphires totaling 11.9 carats and 291 baguette-cut diamonds amounting to 20.54 carats, all set using the "invisible setting" technique. Its reversible case, measuring 49.4 mm in diameter and 16.32 mm in height, features a patented rotation mechanism, allowing either dial to be showcased. The ebony black opaline dials, with gold applied Breguet numerals and a hand-guilloched hobnail pattern, exude elegance. Powered by the manually wound Caliber 300 GS AL 36-750 QIS FUS IRM movement, it offers 20 complications, including a grande and petite sonnerie, minute repeater, alarm with time strike, date repeater, and an instantaneous perpetual calendar. The watch is presented on a shiny black alligator leather strap with square scales and a sapphire-set fold-over clasp.
