Patek Philippe Aquanaut Ref. 5164A-001 – 40.8mm Stainless Steel with Black Embossed Dial on Black Tropical Strap

The Patek Philippe Aquanaut Ref. 5164A-001, widely celebrated as the Aquanaut Travel Time, embodies a perfect synthesis of function, craftsmanship, and modern design. Crafted in stainless steel, this 40.8mm model channels the adventurous elegance that defines the Aquanaut collection.

The black embossed dial, featuring the iconic Aquanaut motif, integrates two central hour hands for dual time zone display — one for local time and another for home time, each paired with day/night indicators. The date subdial at 6 o’clock, synchronized to local time, adds a layer of refinement and utility for the modern traveler.

At its heart lies the Caliber 324 S C FUS, a self-winding mechanical movement admired for its reliability and precision. Through the sapphire-crystal caseback, one can admire the exquisite detailing — Geneva striping, polished bevels, and the engraved Calatrava cross adorning the 21k gold rotor.

The black composite “Tropical” strap, built from an ultra-durable polymer, resists wear, saltwater, and UV exposure — enhancing both comfort and resilience. With 120-meter water resistance and a dual-time function operated through perfectly integrated pushers, the 5164A-001 redefines luxury for those who move seamlessly across borders.
