The Patek Philippe Aquanaut Travel Time reference 5164G-001 is a sophisticated luxury sports watch that marks the first time this complication has been offered in an 18k white gold case. It features a 40.8mm diameter and a slim profile of 10.2mm, characterized by the collection’s signature rounded octagonal bezel with a mix of polished and satin-brushed finishes. The opaline blue-gray dial is embossed with the classic Aquanaut geosphere pattern and paired with matching blue-gray composite rubber strap, creating a contemporary and understated aesthetic.
Technically, the watch is powered by the self-winding caliber 26-330 S C FUS, which provides a power reserve ranging from 35 to 45 hours. Its primary complication is the Travel Time dual-zone mechanism, operated by two pushers on the left side of the case that allow the wearer to jump the local hour hand forward or backward in one-hour increments. The dial includes two small day/night indicators for both home and local time, along with a date subdial at 6 o’clock that is synchronized with the local time.
General reviews of the 5164G-001 are overwhelmingly positive regarding its refined color palette and the tactile ease of its GMT functionality, which many enthusiasts consider the best in the industry. The transition to white gold adds a satisfying weight and prestige compared to the discontinued steel version, though the updated 30-meter water resistance rating has drawn some criticism from purists who viewed the original 120-meter rating as more appropriate for a sports watch. Despite this, it remains highly sought after for its exceptional balance of casual elegance and mechanical utility.
