About the Patek Philippe Aquanaut 5164A-001

The Aquanaut debuted in 1997 as Patek Philippe's modern, sporty counterpart to the Nautilus, distinguished by its rounded octagonal bezel and tropical-style embossed dial. The 5164A-001 sits at the upper end of the Aquanaut reference range, adding the Travel Time complication — a local and home-time display controlled by pushers set into the case — to the core 40.8 mm steel platform. The black dial with its characteristic relief pattern and the integrated black composite strap give this reference a unified, purposeful look that reads equally well dressed up or worn casually. As a steel Patek Philippe with a genuine complication at this size, the 5164A-001 commands consistent demand among serious watch collectors worldwide.

What to Look For

When shopping for a 5164A-001, confirm that both time-zone pushers function correctly and that the original black composite strap and steel deployant buckle are present, as these are specific to the reference and can be costly to replace. Condition of the black embossed dial is a key value driver — examples with no fading, scratches, or lume deterioration command a meaningful premium over those showing wear. A complete set including box, papers, and hang tags significantly increases desirability and resale value for this reference.
