Patek Philippe 5164A Aquanaut Travel Time SS Black Dial

Introduced in 2011, the Patek Philippe 5164A-001 Aquanaut Travel Time in stainless steel with black embossed dial is a defining expression of sporty sophistication within the Aquanaut collection. It houses the self‑winding caliber 324 S C FUS, a refined dual‑time movement featuring a skeletonized second hour hand, local and home day/night indicators, and a date hand at 6 o’clock. The 40.8 mm rounded‑octagonal steel case, measuring approximately 10.2 mm thick, provides a balanced wrist presence, while its 120 m water resistance underscores its utilitarian credentials. The black “tropical” composite strap, renowned for its resilience and comfort, integrates seamlessly with the case and secures via a robust fold‑over clasp. Collectors prize this reference not only for its technical ingenuity—the first Aquanaut to bear a complication beyond a simple date—but also for its role in elevating the Aquanaut’s standing among Patek Philippe’s sports watches. The combination of dual‑time functionality, elegant finishing visible through the sapphire caseback, and the enduring appeal of the Aquanaut design makes the 5164A‑001 a cornerstone for discerning enthusiasts seeking travel‑ready refinement.
