Patek Philippe Nautilus 5712 Guide: References, Price

The Patek Philippe Nautilus 5712 is the moon-phase Nautilus: a 40 mm Genta porthole case with an off-centre dial showing date, moon phase and power reserve on a micro-rotor calibre. It was introduced in 2006 alongside the Nautilus 5711 (steel examples from US$144,530) and, since Patek quietly dropped the steel 5712/1A-001 from its catalogue in early 2025, it has joined the 5711 as a steel Nautilus you can only buy second-hand. This guide covers every 5712 reference, how the moon phase and power reserve work, what each costs in 2026, why the steel version was discontinued, how the 5712 compares with the 5711, and what to check before buying one. Bizak & Co. sources 5712 references to order; browse the Nautilus collection for the configurations we can seek.

Patek 5712 specifications

The 5712 is thinner than the 5711 in feel because the micro-rotor keeps the movement flat, and it is the only Nautilus with an asymmetric dial, which is why owners either love it or choose the cleaner 5711.

How do the moon phase and power reserve work on the 5712?

Moon phase. The moon-phase display sits at 7 o'clock, in the same sub-dial area as the pointer date. A rotating disc carries the moon and shows roughly where the real moon is in its cycle, from new to full and back. It is a simple moon phase, not part of a perpetual calendar, so it does not track months, leap years or the year. Like any moon-phase mechanism it will drift slightly against the real moon over a long period, which is why a service or an owner's adjustment resets it. If the watch has been stopped for a while, set the date and the moon disc before relying on either.

Power reserve. The indicator at 10 o'clock shows how much running time is left in the mainspring. Patek specifies about 48 hours when fully wound for this calibre. The micro-rotor winds the watch from wrist movement, so a watch worn regularly keeps the indicator up, while one left on a shelf for a couple of days will run down and stop. The indicator is a useful check on whether the watch is being kept wound by wear or needs a few turns of the crown.

Setting them. The correct procedure for adjusting the date and moon phase depends on the reference and year, so check the Patek Philippe manual or ask a retailer or the Patek service network before adjusting an unfamiliar watch. If you are comparing the 5712 with other complicated Nautilus watches, our 5726 annual calendar guide and 5740 perpetual calendar guide cover the models that add more calendar functions.

What is a micro-rotor, and why does the 5712 use one?

A conventional automatic movement winds itself with a full-sized rotor that swings above the going train, which adds height to the calibre. A micro-rotor sits inset within the plane of the movement instead of above it, at the cost of some winding efficiency, and the trade is thickness for output. Patek's calibre 240 was developed in 1977 specifically to make an ultra-thin self-winding movement possible, and the 5712 puts it to a fuller use than a simple three-hand watch: alongside the automatic winding it drives a small-seconds subdial, a pointer date, and the moon-phase and power-reserve indications on the same flat base. The trade-off is that a micro-rotor movement is more delicate to service than a full-rotor calibre of similar complexity, and Patek's authorised service network is the appropriate route for a 5712 due for a service.

Is the Patek 5712 discontinued?

The steel 5712/1A-001 is. Patek Philippe removed it from its online catalogue in early 2025 without an announcement, in the same quiet way it has retired other references, and it did not return at Watches and Wonders 2025 or 2026. The rose gold 5712/1R-001 and the white gold 5712G-001 remain in the collection. As with the 5711 in 2021, the discontinuation fixed the supply of steel moon-phase Nautilus watches and pushed secondary prices up through 2025.

How much is a Patek Philippe 5712? Prices in 2026

The only honest way to put a number on a 5712 is to quote a specific ask on a specific day. The table lists what Bizak's sourced catalogue showed on October 6, 2026 for the three references we are most often asked to find, each sourced to order, with the retail context beside it.

• 5712/1A-001 (steel). Last US retail price was in the high US$40,000s. Since discontinuation, unworn full-set examples have sold at auction for well over US$200,000 and dealer asks in 2025 and 2026 have generally sat in the US$150,000 to 250,000 range depending on year, condition and papers. Bizak's catalogue ask of US$178,141 on October 6, 2026 sits in the lower half of that band. Older examples without papers sit lower.
• 5712/1R-001 (rose gold bracelet). Retail in the high US$80,000s to around US$90,000 in 2026. The gold bracelet carries a large premium on the secondary market: Bizak's ask of US$288,400 on October 6, 2026 was the highest of the three and, on that day, above the steel watch. Treat it as one dated observation, not a market rate.
• 5712G-001 and 5712R-001 (strap). Retail in the US$60,000s to 70,000s; secondary asks close to or somewhat above retail, with the strap models the most obtainable 5712s. Bizak's catalogue listed an unworn 5712G-001 at US$103,000 and a pre-owned one at US$77,999 on October 6, 2026. We had no 5712R-001 strap listing that day; expect it to price near the white gold watch, with condition and papers deciding which side.

Those figures are dated observations from one catalogue and will move. Ask for a dated quote for the exact reference, year, condition and papers; our Patek Philippe price guide explains how to compare quotes.

5712 vs 5711: which Nautilus?

The 5712 costs more second-hand because fewer were made and the complication adds value. Buyers who want the purest Nautilus choose the 5711; buyers who want a dial with something to look at choose the 5712. Our Nautilus 5711 guide covers the other side of the comparison.

Where does the 5712 sit in the Nautilus range in 2026?

In 2026 the Nautilus catalogue is built around the 5811/1G-001, the 41 mm white gold time-and-date watch that replaced the steel 5711 in late 2022, with the 5726 annual calendar (steel from US$80,909), the 5980 and 5990 chronographs and the 5740 perpetual calendar above it. The 5712 fills the gap the 5711 left. It is the only Nautilus with a moon phase that is not also an annual or perpetual calendar, the only one with the asymmetric dial, and in rose gold or white gold it is the thinnest complicated Nautilus still being made. Steel buyers who want a time-and-date Nautilus now have no current-production option, which is why the 5712/1A-001 and the 5711/1A trade on the same scarcity and why the 5712's extra complication is priced as a bonus rather than a reason to pay more at retail.

Three guides cover the neighbours. Our 5711 vs 5811 guide explains how the white gold successor moved the entry point for a new Nautilus, the 5811/1G-001 review covers that watch on the wrist, and the 5726 annual calendar guide is the one to read if you want a complicated Nautilus from the current catalogue rather than the secondary market.

Is the Patek 5712 worth the hype?

As a watch, yes: the micro-rotor calibre 240 is one of Patek's best movements, the case is as thin and comfortable as a 5711, and the moon-phase dial is the most distinctive in the Nautilus range. As a purchase at 2026 prices, it depends on whether you want to own it or trade it. Steel 5712 prices are set by scarcity, not by the watch, and they fell along with the rest of the market in 2022 and 2023 before the discontinuation lifted them again. Buy it because you want to wear it.

What is the poor man's Patek Philippe?

Collectors use the phrase for the Aquanaut 5167A (5167s sourced to order from US$77,115), the steel sports Patek that costs roughly half a Nautilus, or for the gold Calatrava dress watches (from US$9,206) that trade at or below retail. If the 5712 is out of reach and you want a complicated Nautilus, the 5726/1A annual calendar is the closest current-production alternative. Our Aquanaut 5167 guide and cheapest Patek guide list the entry points.

Servicing a 5712: what to budget for

The calibre 240 PS IRM C LU adds a moon-phase disc, a pointer date and a power-reserve indication on top of the micro-rotor base, and each of those functions has to be checked and set correctly during a service, not just the going train's rate. A moon-phase disc that has been running for years without adjustment accumulates a small daily error that a service resets; Patek's own moon-phase mechanism is more accurate than the simple 59-tooth wheel used in cheaper watches, but it still drifts over time and is worth confirming against the actual date at purchase. Ask for the last service date and, on an older watch, whether the moon-phase accuracy was checked and reset as part of that service. As with the 5980's chronograph, a documented Patek service adds to the paperwork buyers of a discontinued steel 5712/1A-001 will want to see.

Buying a 5712: what to check

• Papers. The Certificate of Origin cannot be reissued, and an Extract from the Archives is only available for watches sold more than ten years ago. A 2020 5712/1A without papers stays without papers until 2030. Our serial number check guide explains the numbers.
• Moon phase and power reserve. Have both set and check that the moon disc advances and the reserve hand moves as the watch winds. These are the parts that go wrong on a neglected 5712.
• Case finishing. Sharp transitions between brushed and polished surfaces; rounded edges mean polishing.
• Bracelet. Count the links and check for stretch on early steel examples.
• Price against the band. A steel 5712 offered well under the market is the single most reliable warning sign.
