AQUANAUT TRAVEL TIME MODEL, REF. 5164A-001, MOVEMENT NO. 7'136'220, CASE NO. 6'233'597, CIRCA 2018

When it was introduced in 1997, the Aquanaut represented a bold new chapter for Patek Philippe. Conceived as a contemporary, casual alternative to the Nautilus, it appealed to a younger generation of collectors through its modern design and sporting character. The model was notably the first Patek Philippe wristwatch to be fitted with a composite Tropical strap, highly resistant to wear, ultraviolet radiation, and salt water, perfectly complementing its relaxed yet refined aesthetic. Combining exceptional craftsmanship with everyday versatility, the Aquanaut anticipated the rise of the luxury sports watch as an essential category of contemporary watchmaking.

Reference 5164
Introduced in 2011, the Aquanaut Travel Time reference 5164 became the first complicated model within the Aquanaut collection, incorporating Patek Philippe's ingenious dual time-zone mechanism into the model's sporty architecture. Designed for modern travellers, the patented Travel Time system allows the local hour hand to be adjusted independently via discreet pushers integrated into the left side of the case, while day/night indicators for both home and local time ensure exceptional legibility. Retaining the embossed dial, rounded octagonal case, and signature Tropical strap that define the Aquanaut, reference 5164 successfully combines technical sophistication with effortless practicality, making it one of the most desirable modern travel watches in the Patek Philippe collection.
