Two Visions From One Genius

The Audemars Piguet Royal Oak and the Patek Philippe Nautilus share something that no other pair of luxury watches can claim: both were designed by the same man. Gerald Genta, the most influential watch designer of the 20th century, created the Royal Oak in 1972 and followed it with the Nautilus in 1976. Both watches shattered conventions about what a luxury watch could look like. Both are now among the most coveted timepieces on earth.

But which one deserves your wrist — and your investment? Let us break it down.

Design Philosophy

The Royal Oak

The Royal Oak was a provocation. When AP asked Genta to design something radical overnight (literally — the story goes he sketched it in a single evening), he delivered an octagonal bezel with exposed hexagonal screws, inspired by a deep-sea diver's helmet. The case is a masterwork of finishing: brushed flat surfaces transition sharply to polished bevels, creating a play of light that no photograph fully captures.

The "Tapisserie" dial — a waffle-like textured pattern — has become one of the most recognizable dial designs in horology. Every element of the Royal Oak signals intentional, architectural design. It is a watch that looks like it was engineered, not just styled.

The Nautilus

Four years later, Genta approached the Nautilus with a different inspiration: a ship's porthole. The result is softer and more organic than the Royal Oak. The case features rounded "ears" on either side that give it a distinctive horizontal profile, and the bezel has a smooth, continuous curve rather than the Royal Oak's angular octagon.

The Nautilus dial uses a horizontal embossed pattern that catches light differently at every angle — more wave-like and fluid compared to the Royal Oak's grid. Where the Royal Oak feels industrial and precise, the Nautilus feels nautical and elegant.

Case Finishing and Craftsmanship

Both watches are finished to an almost absurdly high standard, but they express that craftsmanship differently.

The Royal Oak's case finishing is often cited as the benchmark for the entire industry. The transition between brushed and polished surfaces is achieved with a sharpness that requires extraordinary skill and time. The exposed screws on the bezel are not just design elements — they are functional, holding the bezel to the case, and each one is individually finished.

The Nautilus achieves its finishing through curves rather than angles. The case is thinner and more ergonomic, and the transitions between surfaces are subtle rather than dramatic. Patek Philippe's finishing is every bit as meticulous as AP's, but it prioritizes smoothness and comfort over visual drama.

Movement

The current Royal Oak (Ref. 15500ST) uses AP's calibre 4302, a modern automatic movement with a 70-hour power reserve and excellent finishing visible through the display case back. AP's in-house movements have improved significantly in recent years, with the 4302 representing the latest evolution.

The Nautilus (Ref. 5711/1A, now discontinued and replaced by the 5811/1G) used Patek's calibre 26-330 S C, offering a 35-45 hour power reserve with the Patek Philippe Seal — one of the most stringent quality standards in watchmaking. The newer 5811 uses the calibre 26-330 S C with updated specifications. Patek's movements are finished to a standard that many consider unmatched.

Market Value and Availability

Both watches are notoriously difficult to acquire at retail, and both command significant premiums on the pre-owned market. The Nautilus, particularly the discontinued 5711/1A in steel, has achieved almost mythical status — pre-owned prices have at times exceeded three to four times the original retail price.

The Royal Oak, while also trading above retail, has seen somewhat more stable secondary market pricing. AP's broader production numbers (relative to Patek) and wider model range contribute to slightly better availability, though "better" is relative — you will still wait years for a steel Royal Oak at an authorized dealer.

For Canadian collectors, the pre-owned market is often the most realistic path to either watch. Both represent significant investments, and both have demonstrated strong value retention over time.

Which Is the Better Investment?

The Nautilus has had the more dramatic appreciation, particularly the 5711. But dramatic appreciation often comes with dramatic risk — prices that spike can also correct. The Royal Oak has shown steadier, more sustainable growth, supported by AP's strong brand positioning and consistent demand.

Both are considered safe stores of value in the luxury watch world. If you are buying purely as an investment, the Nautilus's scarcity gives it an edge. If you are buying to wear with investment upside as a bonus, the Royal Oak's broader model range and slightly better availability may offer a more practical entry point.

The Final Word

Choosing between the Royal Oak and the Nautilus is a deeply personal decision. Both are masterpieces. Both were born from the same creative mind. Both will be coveted long after we are gone. The Royal Oak rewards those who love bold, architectural design. The Nautilus rewards those who prefer understated elegance. Neither choice is wrong.
