The Aquanaut Travel Time 5164A is among the most technically accomplished references in Patek Philippe's sports watch lineup, combining the Aquanaut's now-iconic rounded octagonal case with a dual time zone complication executed entirely through intuitive pushers rather than a crown-operated mechanism. It is a travel watch built for use, not just admiration.

This 2023 example features the black embossed dial, Patek's signature textured surface that gives the Aquanaut its immediately recognizable visual depth. Applied luminous Arabic numerals and hands ensure strong legibility in any light, while the two-timezone display allows the wearer to track home and local time simultaneously, with a local-time quick-set via the pusher system at 8 and 10 o'clock, complete with a day/night indicator for both time zones to eliminate AM/PM ambiguity across any itinerary.

The 40.8mm stainless steel case retains the Aquanaut's characteristic rounded octagonal bezel and integrated rubber strap system, here in black to match the dial. The tropical composite strap is Patek's own compound, engineered for durability and comfort across climates, and fastens with a fold-over clasp in steel. Water resistance is rated to 120 metres, and the sapphire exhibition case back reveals the Calibre 324 S C FUS movement within.

Inside is the in-house Calibre 324 S C FUS, a self-winding movement with a peripheral rotor to preserve visual access to the decoration, running at 28,800 vph with a 45-hour power reserve. The finishing throughout, from the Geneva Seal-adjacent standards Patek holds its movements to, to the tight tolerances of the pusher mechanism, reflects the level of manufacture that makes this reference hard to replicate at any price.
