Overview
The Patek Philippe 5164A-001 is the stainless steel expression of the Aquanaut Travel Time, pairing the line's signature casual-sport aesthetic with a practical dual-time complication. Its 40.8 mm case houses the manufacture Calibre 324 S C FUS, which drives a local-time display adjustable in one-hour increments without interrupting the running movement. The characteristic black embossed checkerboard dial ties the reference unmistakably to the broader Aquanaut family.
History
The Aquanaut line was introduced in the late 1990s as Patek Philippe's more relaxed, contemporary counterpart to the Nautilus, and the Travel Time complication was eventually grafted onto the collection to extend its appeal to frequent travellers. The 5164A-001 entered production in 2011, representing a notable democratisation of the reference by offering the Travel Time in stainless steel — a material Patek Philippe has historically deployed selectively. The reference enjoyed a long production run spanning well into the 2020s, during which it became one of the most sought-after steel sport complications in the manufacture's catalogue.
Notable points
- Calibre 324 S C FUS allows the local (second) time zone to be advanced or set back in one-hour steps via dedicated pushers, without stopping the movement.
- The 40.8 mm stainless steel case gives the 5164A-001 a sportier, more wearable profile than many of Patek Philippe's dress complications.
- The black dial features the Aquanaut's hallmark embossed checkerboard pattern, achieved through a relief-textured surface that adds depth without applied indices.
- Stainless steel references from Patek Philippe have historically been produced in more restrained numbers than their precious-metal counterparts, lending the 5164A a particular standing among collectors.
- The dual-time display presents home and local hours on the same dial, with a day/night indicator for each zone to prevent misreading AM and PM across hemispheres.
