The Patek Philippe Aquanaut Travel Time reference 5164R-001 is a sophisticated luxury sports watch that features a 40.8mm 18k rose gold case with a mix of polished and satin-brushed finishes. It is distinguished by its embossed chocolate brown sunburst dial, which transitions with a subtle gradient and features rose gold applied numerals with luminescent coating. The watch is powered by the self-winding caliber 26-330 S C FUS movement, offering a power reserve between 35 and 45 hours. It is paired with a matching dark brown composite rubber strap and a rose gold patented fold-over clasp, and it maintains a water resistance of up to 120 meters.
The primary complication is the Travel Time function, which displays two distinct time zones through a solid rose gold hand for local time and a skeletonized hand for home time. This system is supported by two separate day/night apertures on the dial and a date sub-dial at the 6 o’clock position that is synchronized with the local time. The time zone can be adjusted easily using two integrated pushers on the left side of the case, allowing the local hour hand to move forward or backward in one-hour increments without stopping the movement or affecting the home time.
General reviews of the 5164R-001 are overwhelmingly positive, often citing it as one of the most practical and wearable complications in Patek Philippe’s modern catalog. Collectors frequently praise the “crossover” appeal of the rose gold and brown color palette, noting that it balances the sportiness of the Aquanaut line with a level of elegance suitable for formal settings. While it is slightly thicker than the standard 5167 model to accommodate the movement, it is widely regarded for its exceptional wrist comfort and legibility. Some enthusiasts note that it serves as an ideal “one-watch collection” for frequent travelers due to its robust build and intuitive utility.
