Patek Philippe Nautilus 5712/1A-001 – A Collector’s Favourite

The 5712/1A-001 Nautilus has long been a favourite among collectors. For nearly two decades, it stood apart from the rest of the Nautilus family: more complex than the 5711, more characterful than the 3700, and more technically satisfying than almost any other steel sports watch of its era. Its quiet discontinuation only increased its popularity, transforming it from a connoisseur’s top pick to a modern legend.

To understand why the 5712/1A occupies such a revered position, one must trace the lineage that shaped it – beginning with the birth of the Nautilus itself, passing through the short-lived 3712/1A, and culminating in the refined evolution that became the 5712/1A.

A Brief History of Patek Philippe’s Nautilus

The Nautilus story begins in 1974, when Gérald Genta sketched its outline in a moment of inspiration that would redefine the luxury sports watch. Inspired by a ship’s porthole, complete with a rounded octagonal bezel and side “ears” resembling watertight hinges, the newly named Nautilus was exactly what Patek Philippe needed to survive the “Quartz Crisis”.

Launched in 1976, the first reference 3700/1A was bold, angular, and distinctive. With a case size of 42mm, the brand new Nautilus was large on the wrist, but its ultra-thin automatic calibre 28-255 C movement allowed it to be incredibly slim. It was unlike anything Patek Philippe had made before, but it quickly became the brand’s most famous design.

For many years, the Nautilus remained a study in elegant simplicity. It was not until 1998, with the introduction of the 3710, that Patek Philippe began to explore complications within the Nautilus line. The 3710/1A “Comet” featured a power reserve indicator at 12 o’clock but otherwise retained the classic Nautilus proportions.

This paved the way for a more ambitious step in 2005, when the reference 3712 appeared – a watch that introduced a trio of poetic complications and signalled a new era for the Nautilus. The following year, Patek Philippe celebrated the 30th anniversary of the model with a refreshed collection, including the now famous 5711 and its more complex sibling, the 5712. Together, these watches ushered the Nautilus into modernity, but it was the 5712 that carried forward the spirit of mechanical artistry that had begun with the 3712.

The 3712/1A – The Original

The Patek Philippe Nautilus 3712/1A is one of the most intriguing short-run references in contemporary watchmaking. Produced for only around nine months in 2005, it was a transitional design – experimental yet foundational. Its asymmetrical dial layout, with the power reserve at 10:30, the moon-phases and pointer date nestled between 06:00 and 09:00, and the small seconds at 04:30, made it unbalanced, unconventional, and instantly memorable.

The 3712 retained the two-piece case construction of earlier Nautilus models, giving it a slightly more vintage character. Its dial details were idiosyncratic: three red dots on the power reserve, inverted date numerals, a more muted grey-blue tone, and eleven hour-markers instead of the ten found in later models. These quirks have become points of fascination for collectors who view the 3712/1A as a snapshot of Patek Philippe in the midst of creative transition.

Despite its brief production run, the 3712 laid the groundwork for everything that would follow. It established the complication set, the movement architecture, and the aesthetic language that the 5712 would go on to refine and elevate. In many ways, the 3712 is the Nautilus at its more daring – a watch that tested the boundaries of the design and opened the door to a more expressive future.

The 5712/1A – The Evolution

When the 5712/1A-001 arrived in 2006, it represented a more mature interpretation of the idea introduced by the 3712. The case size decreased to 40mm and adopted a three-piece construction, giving the watch a more modern profile and improved robustness. The bracelet was re-engineered with polished centre links and a more substantial feel, aligning it with the rest of the 30th anniversary Nautilus family.

The dial, while retaining its beloved asymmetry, became cleaner and more refined. The power reserve gained a fourth red dot, the date numerals were enlarged and no longer inverted, and the hour markers were reduced to ten, creating a more balanced appearance. The blue-black gradient dial also deepened in tone, giving the watch a richer, more luxurious presence. Even the moon-phases disc was updated, now featuring gold-tone stars and a warmer, more romantic aesthetic.

These changes did not alter the essence of the watch; they simply polished it. The 5712 preserved the eccentric charm of the 3712 while elevating it into something more harmonious, more contemporary, and distinctly in line with the brand’s modern identity.

Its discontinuation, carried out quietly and without announcement, only heightened its allure. The steel 5712/1A slipped out of production as discreetly as it had once entered, leaving behind only the rose gold 5712/1R model.

The Movement – Calibre 240 PS IRM C LU

At the heart of both the 3712 and 5712 lies one of Patek Philippe’s most celebrated movements: the calibre 240 PS IRM C LU. This ultra-thin calibre, built around a 22-carat gold micro-rotor recessed into the mainplate, is a triumph of engineering. Measuring just 3.99mm thick, it allows the Nautilus to maintain its signature slim profile even while housing multiple complications.

The calibre 240 PS IRM C LU powers a suite of functions: moon-phases that track celestial movements, a pointer date, a power reserve indicator, and a small seconds subdial. Combined with a 48-hour power reserve and 21,600vph (3Hz) frequency, this movement embodies Patek Philippe’s commitment to precision and performance.

Two decades later, it is still being used to power the 5712/1R-001 in Patek Philippe’s catalogue.

Collector Appeal – 5711/1A vs 5712/1A

The collector narrative surrounding the 5712/1A-001 is inseparable from its relationship with the 5711/1A-010, the most well-known modern Patek. The 5711/1A became a global symbol of unobtainable luxury, worn by celebrities, athletes, and executives. Its clean, symmetrical dial and pure three-hand simplicity made it instantly recognisable, and its scarcity turned it into a status object that transcended the world of watches.

The hype around it reached new heights when Patek Philippe’s 5711/1A-018 “Tiffany” Nautilus, co-signed by Tiffany & Co., realised a staggering $6.5 million at auction.

The 5712/1A, by contrast, appeals to a different sensibility. Its asymmetrical dial, trio of complications, and micro-rotor movement give it a depth that the 5711 never sought to achieve. It is less ubiquitous, less obvious, and far more expressive. Described as the “Insider’s Nautilus”, it is a watch chosen by those who value mechanical nuance over cultural fame.

Where the 5711 is admired for its purity, the 5712 is prized for its personality.

Final Thoughts

The Patek Philippe Nautilus 5712/1A-001 stands as one of the most compelling expressions of the modern Nautilus identity. It bridges heritage and innovation, combining Genta’s original design language with one of Patek’s most elegant movements. Its asymmetry is deliberate, its complications chic, and its presence unmistakable. With its quiet discontinuation, the 5712/1A has entered the realm of contemporary icons – a watch that collectors will pursue and cherish as their most beloved timepiece.
