Patek Philippe Aquanaut 5167A-001
Known as Aquanaut, the steel one on the black strap
The 5167A-001 is the steel Aquanaut on the tropical composite strap, the reference that carried the model from 2007 all the way to its 2025 shakeup. Patek introduced the Aquanaut in 1997 as the 5060, a 35.6mm watch built to bring the Nautilus design language to a younger, more casual buyer. The line grew through the 5065, and in 2007, on the tenth anniversary, Patek replaced it with the 5167. That is when the Aquanaut became the watch collectors argue about today: a 40.8mm case, a sapphire display back showing the automatic caliber 324 S C, and the rounded octagonal bezel with the embossed 'grid' dial that reads as unmistakably Patek from across a room. For eighteen years the 5167A was the entry point into steel Patek sport, sitting a rung below the Nautilus 5711 in the catalog and, for long stretches, right beside it on the waitlist. We handle it constantly on 47th Street because it is the Patek people actually wear: no bracelet to scratch up on a desk, a strap you can swap, water resistance you can trust, and a dial that hides everyday marks better than a polished Nautilus.
Produced: 2007 to 2025. The 5167A-001 launched in 2007 as the tenth-anniversary replacement for the 5065. The bracelet sibling, the 5167/1A, was discontinued by Patek in 2025, and that move reshaped demand across the whole 5167 family.

Market & Value
This is a watch that trades well above its list price and always has. Patek's retail on the steel Aquanaut sat in the high-$20,000s to low-$30,000s range for most of its run, but you have not been able to buy one at a boutique without a relationship or a long wait in years. On the secondary market the 5167A-001 on the strap generally trades in the $32,000 to $55,000 band depending on condition, year, and whether it comes full set with box and papers, and clean, complete examples can push higher when supply is thin. Roughly 85 percent of the examples in the market carry box and papers, so a naked watch takes a real discount from us and everywhere else. Two things move the price hardest: completeness and the strap. A worn or cracked original strap and a missing clasp are cheaper to price around than most buyers expect, so do not let a tired strap talk you out of a watch that is otherwise honest, and do not let a fresh strap convince you a watch is minty. The 2025 discontinuation of the bracelet 5167/1A pulled attention back to the whole reference, and the Nautilus and Aquanaut collections have been among the stronger performers in the recovering Patek market through 2026.
What to Know Before You Buy
First, know which Aquanaut you are actually looking at. The 5167A-001 is the steel case on the black composite strap. The 5167/1A-001 is the same watch on the integrated steel bracelet, it was discontinued in 2025, and it commands a premium over the strap version, so the difference between the two is real money. Second, the caliber 324 S C is a workhorse Patek automatic shared with the Nautilus 5711 and several Calatravas, which means parts and service knowledge are widely available, a genuine advantage over rarer movements. Third, check the date wheel, the crown action, and the caseback view: the sapphire back should show a crisp 21K gold rotor and clean finishing, and a screw-down crown should thread smoothly with no grit. Fourth, the strap and clasp are consumables. Patek straps for the 5167 are available but not cheap, and an original strap in good shape adds to the story on a resale. Fifth, on authenticity, the embossed dial texture, the applied numerals, and the case proportions are hard to fake convincingly, but papers, a matching movement number, and a coherent service history are what actually protect you. Buy the full set when you can.
