The Patek Philippe reference 5164 combines the contemporary styling of the Aquanaut with one of the manufacture's most practical travel complications, creating one of the most versatile luxury sports watches in the collection. Introduced in 2011, the 5164 is powered by the automatic Calibre 324 S C FUS, featuring Patek Philippe's innovative Travel Time mechanism, which allows the wearer to display local and home time simultaneously using independently adjustable hour hands. A date display synchronised with local time and discreet day/night indicators for both time zones make the watch an ideal companion for frequent travellers.

Produced in stainless steel, rose gold and white gold, with a variety of dial colours throughout its production, the reference 5164 retains the Aquanaut's signature embossed dial, rounded octagonal case and integrated composite strap while adding an extra level of mechanical sophistication. Combining exceptional wearability, robust everyday performance and intuitive dual-time functionality, the 5164 has become one of Patek Philippe's most sought-after modern sports watches, admired for its practical complication, understated elegance and enduring appeal among collectors.
