Earlier this year, the watch world saw the end of an era. Patek Philippe officially confirmed the discontinuation of one of its most celebrated modern timepieces: the Aquanaut Ref. 5167/1A-001 on its stainless steel bracelet.
The initial news sent ripples through the community, but now that several months have passed, the dust has settled. This gives us a clearer perspective to analyze the legacy of this incredible watch and the true market impact of Patek Philippe’s landmark decision.
A Modern Legend: The Enduring Legacy of the Ref. 5167/1A
Launched in 2007 to celebrate the Aquanaut’s 10th anniversary, the 5167/1A was a masterful refinement of the original design. As the younger, more adventurous sibling to the legendary Nautilus, the Aquanaut line successfully carved its own distinct identity, with the 5167/1A leading the charge.
Its key characteristics became benchmarks for the industry:
Case: A perfectly proportioned stainless steel case measuring 40.8 mm in diameter. Its signature rounded octagonal bezel is instantly recognizable, with a sophisticated mix of brushed and polished finishes.
Dial: The iconic black embossed dial, reminiscent of a meridian grid, with applied Arabic numerals filled with luminous coating for superb legibility.
Movement: The heart of the watch is the self-winding Caliber 26‑330 S C (which succeeded the Caliber 324 S C), a movement beautifully finished and visible through the sapphire crystal case back, bearing the prestigious Patek Philippe Seal.
Water Resistance: A capable 120 meters, making it suitable for swimming and living up to its “Aqua” name.
It was, in every sense, the definitive “one watch” for a new generation of collectors—equally at home in a boardroom as it was on a beach.

The Great Debate: Steel Bracelet vs. Tropical Rubber Strap
The discontinuation specifically targeted the 5167/1A-001 on the integrated steel bracelet. Its counterpart, the 5167A-001 on the “Tropical” composite rubber strap, remains in the catalog, making the comparison between them more relevant than ever.
| Feature | Patek Philippe Aquanaut 5167/1A-001 (Steel Bracelet) | Patek Philippe Aquanaut 5167A-001 (Rubber Strap) |
|---|---|---|
| Aesthetic | More formal, classic, and integrated. Presents a seamless flow of steel from case to clasp. Often seen as more “luxurious.” | Sporty, modern, and casual. The textured strap mirrors the dial pattern, creating a cohesive, utilitarian look. |
| Versatility | Excellent. Dresses up more effectively, making it a true boardroom-to-beach watch. | Highly versatile but leans more casual. Supreme comfort for daily wear and sporting activities. |
| Comfort | The bracelet is exceptionally well-engineered and comfortable, but heavier than its rubber counterpart. | Unmatched comfort and lightness. The composite material is durable, waterproof, and hypoallergenic. |
| Market Status | Discontinued (2025). Officially a historic reference with a fixed supply. | In Production. Carries the torch for the steel Aquanaut line as the currently available reference. |
The Aftermath: What We’ve Learned
The moment production ceased, the Ref. 5167/1A-001 transitioned from a production piece to a collectible. Now, we can move past prediction and look at the observable effects.
A Modern Classic Solidified
The discontinuation was the final ingredient needed to cement the 5167/1A-001’s place as a modern classic. This change in status from “in production” to “historic” is permanent and fundamentally alters its position in the world of collecting.
The Real-World Impact on Value and Availability
As anticipated, the secondary market reacted swiftly and decisively. In the months since its discontinuation, we have witnessed a clear and significant trend:
For Current Owners: In the months since its discontinuation, we have witnessed a clear and significant trend: a 15% increase in market value for examples in excellent condition. The piece is now more sought-after than ever, solidifying its reputation as a blue-chip collectible. (as of August 2025)
For Aspiring Buyers: With the supply from authorized dealers cut to zero, the pre-owned market is the only venue. Demand has consistently outstripped the finite supply, reinforcing its top-tier price point and making well-preserved examples increasingly difficult to acquire.
A Final Word
The retirement of the Patek Philippe Aquanaut 5167/1A was a landmark event for the watch community this year. It marked the end of an era for a watch that defined modern, understated luxury for over a decade.
While it is no longer available new, its departure from the catalog has only enhanced its powerful legacy. The 5167/1A on a steel bracelet is not just a great watch; it is now, and forever will be, a cherished piece of Patek Philippe history.
