Patek Philippe Ref. 5712 – The More Important Nautilus Watch
The story of the Patek Philippe Ref. 5712 is quite ironic. For nearly two decades, it lived in the shadow of its simpler sibling, the Ref. 5711. The Ref. 5711 boasted long pre-order lists and commanded premiums in the secondary market; its cultural influence transcended the watch itself. However, it was the Ref. 5712 – more understated, with a more refined mechanical design and more meticulous watchmaking – that showcased the true essence of Patek Philippe. Even today, the truly important watches remain the lesser-known ones.
To understand the Ref. 5712, we need to go back to 1976, not its debut in 2006. That year, Gérald Genta’s sketches ultimately became the Nautilus 3700/1A watch—a luxury sports watch in stainless steel, featuring an integrated bracelet, a case inspired by portholes (water-resistant to 120 meters), and a slim movement, resulting in elegant and flowing lines. Genta’s brilliance lay in his deep understanding that Patek Philippe’s sports watches must always maintain the essence of Patek Philippe. This principle permeated the design of all subsequent Nautilus replica watches, with the 5712 watch embodying this concept to its fullest extent.
From 3712 to 5712 The complicated Nautilus watch did not begin with the 5712. This honor belongs to the 3712/1A launched in 2005—the first Nautilus watch to feature a power reserve indicator, moon phase, and date display sub-dial. It was equipped with the same 240 PS IRM C LU movement as its successor, but the case structure retained the early design of the 3710/1A-001 “Comet.” The 3712’s production cycle was only about one year, making it one of the shortest-production-cycle yet most sought-after modern Nautilus watches. It was a proof of the concept; while the 5712 represented the final form.
At Baselworld 2006, Patek Philippe simultaneously launched the 5711/1A and 5712/1A-001 watches. These two watches incorporated the complications of the 3712 into a completely modern case: a power reserve indicator at 10 o’clock, a moon phase display at 7 o’clock, and a pointer-style date display at 2 o’clock. This asymmetrical layout presented a visual complexity unmatched by the symmetrical 5711.
The 5712 has a 40mm diameter and approximately 8.52mm thickness, giving it a discreet and understated appearance, unrelated to its mechanical performance.
For those familiar with its predecessor, the Nautilus ref. 3712, distinguishing between ref. 3712 and ref. 5712 is quite easy, relying solely on subtle differences on the dial. For those less familiar with these two replica luxuy watches, here are their main differences and distinguishing features:
The power reserve indicator on the ref. 5712 has four red dots before the number “12,” while the ref. 3712 has only three.
The date display numerals on the 5712 are significantly larger than those on the 3712. Furthermore, the numerals “11” through “23” are inverted on the 3712, but not on the 5712.
The 5712 model has only 10 hour markers on its dial, while the 3712 model has 11, including a small marker at 7 o’clock. Furthermore, the 8 o’clock marker on the 3712 model is slightly longer, and the 6 o’clock marker is complete, unlike the 5712 model which is slightly obscured by the date display.
The moon phase complication on the 5712 model has a more golden hue for the moon and stars, compared to the deep silver of the 3712 model.
The hour and minute hands on the 5712 model are thinner.
The dial on the 3712 model has a more grayish-blue hue.
The Calibre 240 PS IRM C LU, introduced in 1977, is one of the most important movements in Patek Philippe’s modern history. At only 2.53 mm thick, it was one of the thinnest automatic movements at the time, thanks to its integration of a 22K gold micro-rotor into the mainplate, rather than being placed on top of the movement like a traditional full-length rotor. https://www.whereguidewatch.com/
The suffix PS IRM C LU reveals the rest: small seconds, a reserve indicator, a calendar, and a moon phase. Despite its impressive functionality, the entire movement is only 3.88 mm thick—an incredible figure considering its exceptional performance. Patek Philippe chose to expand upon the Caliber 240, a movement originally designed for dress watches, proving that complications and sports watches are not necessarily incompatible.
Three metals, three figures.
The stainless steel ref. 5712/1A-001 watch, with its blue-black gradient dial, is a true classic. Its appearance on the pre-order list sparked countless discussions about “if I could only own one Patek Philippe watch,” and after production ceased in January 2021, its secondary market price soared to several times its retail price.
The 5712G-001 watch, crafted in 18K white gold with a matching blue dial and alligator leather strap, offers collectors a new way to own a stainless steel watch without the long wait. The white gold gives the watch a composed quality that stainless steel lacks, despite the rich cultural heritage of stainless steel itself.
In 2022, the 18K rose gold 5712/1R-001 fake luxury watch adopted a completely different design concept. Its brown-black gradient dial softens the original industrial style of the Nautilus series, making it warmer and more classic. This watch remains the least discussed model in the Nautilus collection, but perhaps the most beautiful. More importantly, it’s the only 5712 still in production – a significant point as the Nautilus series approaches a milestone year.
What did the market miss?
For most of its production run, the 5712 commanded only a fraction of the secondary market premium of the 5711. This made it somewhat undervalued. The 5712 boasts a more complex movement, a more interesting dial layout, a more distinctive visual character, and a slightly smaller case size – qualities traditionally valued by seasoned collectors. However, the 5711’s clean, simple design made it a dream for a generation of buyers whose interest in watchmaking often lay more in social connections than in the mechanics itself.
The 5712 attracted another type of buyer: those who valued the craftsmanship rather than brand recognition. It was known as the “Nautilus of connoisseurs” – a title that was both a compliment and an insult. In 2021, Patek Philippe discontinued the stainless steel version, and the price quickly fell. The platinum version also quickly disappeared from the catalog. However, the rose gold 5712/1R has remained a bestseller to this day—a subtle indication that Patek Philippe never intended to completely end this chapter of its history.
Heritage—and Future Outlook
The Nautilus watch will celebrate its 50th anniversary in 2026. As we analyzed in our “Nautilus 50th Anniversary Outlook,” all the signals from Geneva point to precious metals and more complex craftsmanship, rather than a return to stainless steel. Mr. Thierry Stern has made it clear that Patek Philippe belongs in the gold and platinum watch category, and the strategic discontinuation of the stainless steel 5711, 5980, and 5712 is not accidental, but a predetermined strategy.
Within this framework, the continuation of the 5712/1R rose gold version is not accidental. It allows the 240 PS IRM C LU movement to be carried on within the Nautilus collection. Whether Patek Philippe commemorates its anniversary with new complications in the Nautilus series (such as minute repeater, split-seconds chronograph, and annual calendar travel time) or reinterprets existing models in precious metals, the essence of the 5712 movement will continue to be passed down.copy luxury watches
The 5711 is the Nautilus watch that everyone dreams of, while the 5712 is the Nautilus watch that Patek Philippe had to create. Fifty years after Genta’s design sketches changed the watchmaking industry, perhaps the more worthy question to explore is: the story of the 5712 is not about to end, but rather about to begin a new chapter.
