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

The Patek Philippe Aquanaut Ref. 5164A, known as the Travel Time, combines refined Swiss engineering with contemporary sport-luxury design. Crafted in stainless steel, this 40.8mm masterpiece is designed for the modern traveler — offering elegance, resilience, and technical precision in one iconic form.

The black embossed dial, adorned with the signature Aquanaut pattern, features dual time zone functionality through two central hour hands: one for home time and another for local time, each with a day/night indicator. The date subdial at 6 o’clock, linked to local time, adds functional sophistication to its clean and balanced layout.

At the heart of the 5164A is the Caliber 324 S C FUS, a self-winding mechanical movement visible through the sapphire-crystal caseback. Its finely finished bridges, polished bevels, and the 21k gold rotor engraved with the Calatrava cross testify to Patek Philippe’s legendary craftsmanship.

The watch is paired with a black composite “Tropical” strap, engineered for durability against saltwater, UV rays, and daily wear — perfectly merging technical prowess with understated luxury. With 120-meter water resistance, the 5164A stands as the ultimate expression of utility refined by artistry.
