The Patek Philippe Aquanaut Ref. 5168G-001 expands the Aquanaut lineage with a luxurious yet understated presence in 18k white gold. Introduced to mark the 20th anniversary of the Aquanaut collection, this model is affectionately known as the “Jumbo” for its larger 42.2 mm case size — the largest Aquanaut to date. Its sunburst blue dial darkens gradually toward the edges, producing a stunning gradient effect that transitions from vivid ocean blue to deep navy. The embossed checkerboard pattern, white gold applied numerals, and Super-LumiNova-coated hands ensure perfect readability and dynamic character. At its heart beats the Patek Philippe Calibre 324 S C, an automatic movement showcasing impeccable finishing, the Gyromax® balance, and a Spiromax® silicon balance spring for precision and magnetic resistance. Displayed through the sapphire crystal caseback, the movement is finished to the highest standards of the Patek Philippe Seal. The composite blue rubber strap, water-resistant and highly durable, integrates seamlessly with the curved lugs and is secured by an 18k white gold fold-over clasp. Water-resistant to 120 meters, the Aquanaut 5168G-001 merges everyday functionality with the sophistication of haute horlogerie — an ultimate expression of modern luxury and precision.
