The Patek Philippe Grand Complications Ref. 5531G-001 is a masterpiece that seamlessly blends artistry with horological innovation. Encased in 18K white gold, this timepiece features a Grand Feu cloisonné enamel dial depicting a Belle Époque steamship on Lake Geneva, a testament to Patek Philippe's Rare Handcrafts. Launched in 2017, it introduced the first minute repeater that chimes the local time, complemented by a world time function and 24-hour day/night indications for all 24 time zones. The case showcases a hand-guilloched hobnail pattern and skeletonized lugs, enhancing its elegance. The watch is powered by the self-winding Caliber R 27 HU movement, offering a power reserve of approximately 43 to 48 hours. The alligator leather strap with square scales, hand-stitched in a shiny blue-green hue, adds a refined touch.
