Patek Philippe Aquanaut 5164A – Black Dial, Black Rubber, 40.8 mm

It does not shout. It whispers legacy.

The Aquanaut Travel Time 5164A-001 brings dual-time capability into Patek’s luxury-sport line with effortless poise. Encased in stainless steel, its 40.8 mm rounded-octagonal form blends high polish and satin-brushed surfaces and wears more compact than the size suggests, around 10.2 mm thick. The hyper-textured black embossed dial evokes subtle depth and hosts dual time-zone indicators, day/night apertures at 3 and 9 o’clock, and a local-date subdial at 6 o’clock—a rich layout that remains clear and functional.

Its movement, the self-winding Caliber 324 S C FUS, reliably supports dual time, seconds, date, and day/night functions, operating at 4 Hz for a 35–45-hour power reserve. The sapphire caseback reveals refined movement finishing, including a gold rotor. With 120 m water resistance and a screw-down crown, it upholds both sporty functionality and refined aesthetics perfectly.
