If the Nautilus is Patek Philippe’s classic yacht, the Patek Philippe Aquanaut is its sleek, modern speedboat—sporty, confident and built for a new generation of collectors who want luxury that can actually keep up with their lifestyle.
First launched in 1997, the Aquanaut was a bold move for a maison known for dress watches and traditional complications. It took Patek’s heritage and wrapped it in rubber, steel and casual elegance—and the watch world has been obsessed ever since. Patek Philippe SA+1
In this post, we’ll explore what makes the Aquanaut so desirable, which models collectors love, and why working with a specialist like AristoHK is one of the smartest ways to add one to your collection.
A Sport Watch With Serious Pedigree
The Aquanaut was designed to answer a simple question:
What does a Patek look like on the wrist of someone who lives in sneakers and travels non-stop?
Patek Philippe answered with:
A rounded octagonal case that subtly echoes the Nautilus, but with its own softer, more contemporary lines. Patek Philippe SA+1
A bold, embossed “grenade” pattern dial, with big Arabic numerals and luminous hands for instant legibility.
A revolutionary (at the time) “Tropical” rubber strap—resistant to water, UV, salt and wear—paired with high horology finishing and movements.
It was casual, but still undeniably Patek Philippe: hand-finished, beautifully proportioned and powered by serious in-house calibres. Over the years, that blend of relaxed style and pure watchmaking has made the Aquanaut one of the most coveted modern sport-luxury watches on the planet. The 1916 Company+1
Design: Understated, But Far From Simple
At a glance, the Patek Philippe Aquanaut looks clean and minimal. Look closely, and you see why collectors obsess over it.
The Case
The Aquanaut’s case combines polished and satin-brushed surfaces for a dynamic play of light, with:
Rounded octagonal bezel
Slim, curved lugs that hug the wrist
Screw-down crown for proper sport-watch robustness
Depending on the reference, case sizes range from compact and versatile to the larger “Jumbo” presence—like the 42.2 mm white-gold models that still manage to wear comfortably thanks to their slim thickness. Patek Philippe SA+1
The Dial
The dial is where the Aquanaut’s character really lives:
Embossed checkerboard texture that matches the strap pattern
Bright, high-contrast Arabic numerals in white gold filled with lume
Simple, functional layouts—time and date, or travel time, or chronograph—designed to be read at a glance
Add in playful yet sophisticated colours—black, grey-brown, blue, khaki green and more—and you get a watch that’s sporty without being loud. Patek Philippe SA+1
Movements: Patek Philippe, No Compromises
This may be Patek’s “casual” line, but nothing about the movements is casual.
Aquanaut references are powered by in-house automatic calibres such as:
Calibre 26-330 S C – Time and date, beautifully finished, slim, and used in several time-only Aquanaut models. Financial Times
Calibre 324 S C FUS – The famous Travel Time movement, offering a clever dual time-zone function with day/night indicators and date tied to local time. It’s practical, elegant and loved by frequent travellers. Patek Philippe SA+1
Through the sapphire caseback on many models, you’ll see:
Geneva Seal–level finishing
Polished bevels and Geneva stripes
A 21k gold rotor gently swinging over the bridges
It’s the kind of finishing that reminds you: this isn’t just a “sport watch”—it’s a Patek.

4. Complications & New Releases
In recent years, Patek has introduced more complex Aquanaut models, including chronographs and even an annual calendar with moonphase, proving the collection has become a true pillar of the brand rather than a side project. 41watch.com+1
