The Patek Philippe Grand Complications Ref. 5374/300P-001 is a masterpiece that seamlessly combines horological complexity with haute joaillerie. This platinum timepiece features a blue-lacquered dial encased in a case adorned with 120 baguette-cut diamonds and 13 baguette-cut blue sapphires, totaling 12.34 carats. The dial showcases a black-gradient rim, sapphire hour markers, and diamond minute markers, all set against an 18K gold dial plate. Powered by the self-winding Caliber R 27 Q movement, it offers a minute repeater with 'cathedral' gongs and a perpetual calendar with indications for day, date, month, leap year, and 24-hour format. The watch is completed with a shiny dusk blue alligator leather strap and a diamond-set fold-over clasp.
