Specs, Market Price & Buying Guide
- The Patek Philippe Aquanaut 5167A is the steel sports Patek on a composite 'Tropical' rubber strap: 40.8mm rounded-octagonal case, embossed relief dial, and an in-house automatic (Calibre 324 S C on earlier examples, 26-330 S C on later ones).
- Market range: roughly $50,000–$68,000 depending on year and set, against a last-known retail near $25,000 (verified 2026-08-23 — recheck before acting).
- Availability (checked 2026-08-23): allocation-gated at ADs and reported leaving the catalog around 2025 — treat as secondary-market only and verify production status with Patek.

Checked 2026-08-23: effectively unavailable at retail without a long AD relationship, and multiple 2025–26 dealer guides report the reference leaving the catalog — verify status with Patek; the secondary market is the practical route.

How it wears, by wrist size
Excellent — 40.8mm wears compact thanks to the rounded case and close-fitting strap.
The sweet spot; slim enough to vanish under a cuff.
Comfortable and discreet — this is the anti-flex Patek.
Proportionate; if you want more presence, the 42.2mm 5168G is the 'Jumbo' Aquanaut.
Buy or skip?
Editorial take: 8.5/10 — the wearable steel Patek, priced by scarcity.
The 5167A is the Aquanaut most people picture: understated, thin, genuinely water-resistant, and finished to Patek standard. The uncomfortable truth is that you will pay roughly double retail for the privilege — a scarcity premium, not a quality premium. If you can live with that, it is one of the most wearable high-end sports watches ever made.
- You resent paying over retail on principle — entirely fair; look at the Calatrava or a pre-owned Nautilus-adjacent instead
- You want a bracelet — that is the 5167/1A, at a further premium
- You want an overt status signal — the Aquanaut flies under the radar, by design

Frequently asked questions
Is the Patek Philippe 5167A discontinued?
Multiple 2025–26 dealer guides report the 5167A leaving the catalog, and Patek does not announce such moves publicly. As of our last check (2026-08-23), treat it as secondary-market only and verify with Patek.
What is the lug-to-lug of the 5167A?
Approximately 48mm by editorial measurement on the 40.8mm case; the integrated strap keeps the footprint compact. Verify against manufacturer data if precision matters.
Is the Aquanaut 5167A a good investment?
It has held value strongly and scarcity supports it — but you would be buying after a decade of appreciation, not before. Buy it to wear it; past performance is not a guarantee, and this is not financial advice.
5167A vs Nautilus 5711 — which?
The 5711 is the grail with the Genta pedigree and the bigger premium; the 5167A is younger, sportier, roughly half the market price, and arguably the better daily watch (120m, rubber strap). Most buyers choose on budget and availability.
What movement is in the 5167A?
Early examples run the Calibre 324 S C; from around 2019 the Calibre 26-330 S C with hacking seconds. Both are in-house Patek automatics under the Patek Philippe Seal — verify by the watch's year.
How does the Aquanaut strap sizing work?
The composite strap is cut to size at delivery and pairs with a fold-over clasp. Get the sizing done by a dealer — mistakes are expensive, and replacement straps are a service item.
Why is a steel Patek on rubber so expensive?
Allocation: Patek makes far fewer steel sports watches than the market wants, and ADs reserve them for established clients. The secondary price reflects immediate availability, not just the object.
Where to buy safely
Effectively closed to new clients for steel sports references — allocation follows years of purchase history.
The practical route at $50K–$68K. Buy the seller: box/papers, service history, escrow, and a written authenticity guarantee.
Strong for unusual or early examples; factor the buyer's premium (20%+).
Highest risk at this price — meet at a watchmaker or Patek boutique and authenticate before money moves; inauthentic Aquanauts circulate widely.
