In the fiercely debated world of high-end Swiss watchmaking, symmetry is usually king. Yet, one of the most coveted, waitlisted, and historically significant watches on the planet threw symmetry entirely out the window.
Enter the Patek Philippe Nautilus Ref. 5712.
Often overshadowed in mainstream pop culture by its minimalist, time-and-date sibling (the 5711), the 5712 is what true collectors consider the “thinking man’s Nautilus.” It is perfectly, deliberately imbalanced—an elegant rebel in a porthole-inspired case.
Whether you are a seasoned collector looking for production nuances or an enthusiast dreaming of your next grail, this is your definitive breakdown of the Patek Philippe Nautilus 5712.
The Origin Story: The Rare “3712” Predecessor
You cannot understand the 5712 without first looking at the ghost that came before it: The Reference 3712.
In 2005, Patek Philippe shocked the watch world by releasing the 3712. It packed a power reserve, moon phase, date, and running small seconds into the sporty Nautilus case. At the time, purists found the dial bizarre and cluttered. It was a stark departure from Gerald Genta’s original, clean 1976 design.
Production of the 3712 lasted for barely a year, with an estimated 500 pieces ever made.
Then, in 2006, to celebrate the 30th Anniversary of the Nautilus, Patek discontinued the 3712 and replaced it with the 5712. While they look nearly identical at a passing glance, the transition marked a major shift in modern Nautilus case manufacturing.

Spotting the Difference: 3712 vs. 5712
If you ever find yourself inspecting a Nautilus complication at an auction, here is how you tell the ultra-rare 3712 from the 5712:
The Power Reserve Dots: The 3712 has three red dots at the end of the power reserve track. The 5712 has four red dots (though a very early batch of 5712s between 2006 and 2008 retained the three-dot layout).
The Case Construction: The 3712 uses a traditional 2-part “monobloc” case like the original 1970s Nautilus. The 5712 ushered in a more modern, 3-part case construction. When inspecting the modern three-part case of the 5712, collectors should pay close attention to the winding crown. Within this specific brand lineage, a single dash emblem on the crown denotes the water resistance standard, and this exact marking applies to both the stainless steel (5712/1A) and the two-tone (5712GR) configurations.
The Dial Details: The 3712 has a slightly smaller date dial, allowing a small hour marker to squeeze in at 7 o’clock, which the 5712 removes entirely.
The Engine: Caliber 240 PS IRM C LU
The chaotic beauty of the dial layout isn’t an arbitrary design choice; it is strictly dictated by the mechanics of the movement inside. At the heart of the 5712 beats the Caliber 240 PS IRM C LU.
Key Insight: The letters in the caliber name actually translate the watch’s functions from French: PS (Petite Seconde / Small Seconds), IRM (Indicateur de Réserve de Marche / Power Reserve Indicator), C (Calendrier / Date), and LU (Lune / Moon phase).
The magic of this movement is its slenderness. The Caliber 240 PS IRM C LU is an automatic movement powered by a recessed 22k gold micro-rotor. It is a highly accurate, free-sprung movement that Patek Philippe tests in six different positions (as opposed to the standard five used by many other luxury brands) to ensure extreme precision, running at a dependable -3 to +2 seconds per day.
To see these complications come together in the warmth of the 18k rose gold 5712R, check out this quick hands-on look. Take note of how the 48-hour power reserve sits cleanly at the top of the dial, while the moon phase—so precise it only needs to be reset once every 122 years—anchors the bottom left:
The Modern 5712 Lineup: Which One Is Yours?
Since 2006, the 5712 has been rendered in several metals, from high-complication stealth wealth to unabashed gold glamour.
The Classic Steel & The Elusive Tiffany Dial
The most recognizable variant is the stainless steel 5712/1A with its iconic blue gradient dial and integrated steel bracelet. However, for elite collectors, the ultimate prize is a steel variation featuring the highly coveted Tiffany & Co. retailer stamp.
The Discontinued Heavyweights: 5712G and 5712GR
While steel dominates the sports watch conversation, the discontinued precious metal variants offer entirely different wearing experiences.
For those who prefer an understated approach, the white gold 5712G paired with an alligator leather strap offers exceptional elegance without the flash of a gold bracelet. Notice how the slate gray dial interacts with the light in this showcase:
Conversely, if you want something that bridges the gap between warm and cool tones, the two-tone 5712GR (combining rose and white gold) is an exceptionally rare find on the secondary market. Get a closer look at the stunning contrast of the 5712GR here:
The Verdict: Why It Remains a Grail
The Patek Philippe Nautilus 5712 commands immense premiums on the secondary market—often tracking right alongside, or slightly above, the discontinued 5711.
But beyond the hype and investment potential, the 5712 is genuinely one of horology’s most compelling creations. It takes the Genta sports watch formula and injects it with haute horlogerie romance (the moon phase) and mechanical anxiety (the power reserve). It is a watch that asks you to look a little closer and embrace the beauty of asymmetry.
