Patek Philippe Aquanaut 5164

The Patek Philippe Aquanaut reference 5164, known as the Travel Time, introduces a dual time zone complication to the Aquanaut collection. This reference maintains the distinctive rounded octagonal case shape and integrated strap design characteristic of the Aquanaut line, while adding practical functionality for travelers. It represents a more complex offering within the Aquanaut family, catering to those who require a sophisticated yet robust timepiece for global use. The 5164A-001 variant features a stainless steel case measuring 40.8 mm in diameter and 10.2 mm in thickness. It houses the self-winding caliber 324 S C FUS movement, which provides a power reserve of approximately 45 hours. The watch is fitted with a sapphire crystal and offers water resistance up to 120 meters. The dial is typically black embossed, and the watch is secured by a composite strap with a fold-over clasp. This reference appeals to collectors seeking a Patek Philippe with a practical complication suitable for daily wear and travel. Its stainless steel construction and composite strap make it a durable option compared to more formal complications. The Travel Time function, indicated by two skeletonized hour hands for home and local time, along with day/night indicators for both, positions the 5164 as a highly functional piece within the broader Patek Philippe sports watch catalog.
