The Patek Philippe Grandmaster Chime is a masterful creation featuring a manually wound Caliber 300 GS AL 36‑750 QIS FUS IRM movement. This double-faced reversible timepiece showcases grande and petite sonneries, a minute repeater with classic gongs, and an array of complications, including an instantaneous perpetual calendar, dual time zones, moon phases, and a date repeater. The ebony black opaline dials are adorned with gold-applied Breguet numerals and a hand-guilloched hobnail pattern. Set in a white gold reversible case with a diameter of 49.4 mm and a height of 16.32 mm, it boasts 96 baguette-cut emeralds (6.99 ct) and 291 baguette-cut diamonds (20.54 ct), complemented by a shiny black alligator leather strap with a fold-over clasp set with emeralds.
