The Patek Philippe 5308G-001 is a monumental achievement in high horology, introduced in 2025 as the brand’s most technically complex wristwatch currently in production. Crafted in white gold, this Grand Complication houses four of Patek Philippe’s most prestigious mechanisms in a single, elegantly balanced timepiece: a minute repeater, a split-seconds monopusher chronograph, and an instantaneous perpetual calendar. The 42mm case is imposing yet refined, with polished white gold surfaces and a sapphire caseback that reveals the exceptional finishing of the R CHR 27 PS QI movement—featuring 799 components, 12 patents, and a 65-hour power reserve.

The watch is distinguished by its radiant ice blue opaline dial. The dial layout is masterfully symmetrical, with twin day/month apertures at 12 o’clock, date and moonphase at 6, and dual chronograph subdials at 3 and 9 o’clock. Leaf-shaped white gold hands and applied hour markers complete the elegant visual composition. With all calendar indications advancing instantaneously at midnight, and the split-seconds chronograph controlled by a single pusher, the 5308G-001 is not just a showcase of complications—it’s a mechanical tour de force, representing the pinnacle of modern Patek Philippe watchmaking.
