The Patek Philippe Grandmaster Chime Ref. 6300/403G-001 is a masterpiece that seamlessly blends haute horlogerie with haute joaillerie. This double-faced reversible wristwatch is encased in white gold and adorned with 118 baguette-cut emeralds (7.87Ks) and 291 baguette-cut diamonds (20.54Ks), all set using the "invisible setting" technique. It boasts 20 complications, including five acoustic functions such as a minute repeater, grande and petite sonnerie, and a patented alarm with time strike. The watch features a manually wound mechanical movement, Caliber 300 GS AL 36‑750 QIS FUS IRM, and offers a 72-hour power reserve. The ebony black opaline dials with gold applied Breguet numerals and hand-guilloched hobnail pattern add to its elegance. The watch is completed with a hand-stitched, shiny black alligator leather strap and a fold-over clasp set with emeralds.
