Patek Philippe Nautilus 5740/1G Guide: Perpetual Calendar History, Price and Buying Checks

Patek Philippe Nautilus 5740/1G-001 perpetual calendar in white gold with blue sunburst dial and integrated bracelet

Quick answer: the Patek Philippe 5740/1G-001 Nautilus perpetual calendar lists in the low six figures on patek.com as of November 2, 2026, and pre-owned examples have generally asked between about US$200,000 and 300,000 since 2025, because the watch is allocated rather than freely sold. It is a 40 mm, 8.42 mm thick white gold Nautilus with a calendar that corrects itself for month lengths and leap years.

The Patek Philippe Nautilus 5740/1G-001 is the perpetual calendar Nautilus: the most complicated watch in the Nautilus range and, at 8.42 mm, also the thinnest. Introduced at Baselworld 2018 in white gold with a blue dial, it put Patek's ultra-thin calibre 240 Q, the movement from the classic 3940 and 5140 perpetual calendars, inside the Genta sports case for the first time. This guide covers the 5740's specifications and history, what it costs at retail and on the secondary market in 2026, how its perpetual calendar works, why it is regarded as one of the hardest Pateks to be offered, the Tiffany-stamped examples, and what to check before buying. Bizak & Co. sources the 5740 to order; the Nautilus collection lists the configurations we can seek.

Patek 5740 specifications

Attribute 5740/1G-001
Case 40 mm across the 10 to 4 o'clock axis, 8.42 mm thick; white gold, integrated white gold bracelet with fold-over clasp
Movement Calibre 240 Q, ultra-thin automatic perpetual calendar with 22 ct gold micro-rotor, 3.88 mm thick, 38 to 48 hours power reserve, Patek Philippe Seal
Functions Hours and minutes; day and 24-hour indication at 9; month and leap-year cycle at 3; date and moon phase at 6
Calendar Perpetual: accounts for month lengths and leap years, needs no correction until 2100
Dial Blue sunburst with horizontal embossing, applied white gold hour markers with luminous coating
Water resistance 60 m at launch; Patek's unified 30 m rating applies to current listings

Three subdials give the 5740 the classic Patek perpetual layout, but because the calibre 240 Q is so flat the finished watch is thinner than a steel 5711 with a plain date. That is the engineering point of the reference: a grand complication that wears like a time-only sports watch.

What does the Patek 5740/1G-001 reference mean?

Patek references are read in parts. 5740 identifies the model, the Nautilus perpetual calendar. The /1 suffix marks the bracelet version in the Nautilus family, G stands for white gold, and -001 identifies the dial and finish variant; that is why you will see the full name written as 5740/1G-001. Our reference numbers guide covers the rest of the system.

How does the 5740's perpetual calendar work?

A perpetual calendar is a mechanical memory of the Gregorian calendar. The movement tracks the length of each month, including February, and the four-year leap cycle, so the date advances correctly without a manual correction at the end of short months. On the 5740 the display is spread across the dial: day and 24-hour indication at 9, month and leap-year cycle at 3, and date with moon phase at 6. Patek's own figure is that no correction is needed until 2100, when the Gregorian calendar skips a leap year. The practical rule for owners is simple: keep the watch wearing or on a winder so it does not stop, and never use the case correctors while the calendar is mid-change, between roughly 8 pm and 4 am. If you want a calendar complication in a lower-cost Nautilus, the 5726 annual calendar is the nearest alternative; it needs one correction a year, at the end of February.

If you are comparing the Nautilus with other perpetual calendars, our perpetual calendar watches collection and the Patek Philippe Grand Complications collection show the wider field we can source.

What is the history of the Patek 5740?

Patek marked the Nautilus's 40th anniversary in 2016 with the 5711/1P and 5976/1G limited editions, then followed in March 2018 with the 5740/1G-001 as the first perpetual calendar in the collection. It was launched only in white gold on a bracelet, a deliberate step away from the steel-heavy Nautilus catalogue, and it has stayed that way: no steel, rose gold or strap version has been made. The calibre 240 Q it uses dates from 1985, when Patek introduced it in the 3940, which means the 5740 combines the collection's most modern case with one of its most proven movements.

How much does a Patek Philippe 5740 cost? Prices in 2026

  • Retail. On November 2, 2026, patek.com showed a US list price in the low six figures for the 5740/1G-001. The 5740 launched in 2018 at roughly US$120,000. Allocation goes to established boutique clients, and the 5740 is one of the references Patek uses to reward long relationships, so waiting time at retail is measured in years. Confirm the current figure with an authorised Patek boutique, since it can change.
  • Secondary. Asks for unworn full sets have generally run from around US$200,000 to 300,000 in 2025 and 2026, down from the peak above US$400,000 in early 2022 but well above retail. Earlier examples with worn bracelets sit at the lower end.
  • Tiffany-stamped. A handful of 5740/1G-001s were sold through Tiffany & Co. with the double-signed dial; these trade at a substantial premium to the standard dial and appear rarely. Our Tiffany Patek guide covers what the stamp means and how to check it.

What makes the Patek 5740 so special?

Three things. It is the only perpetual calendar in the Nautilus range, so anyone who wants that complication in that case has one option. It is the thinnest Nautilus made, thinner than the 5711, because the calibre 240 Q measures 3.88 mm. And it is made in small numbers in a precious metal, so it never went through the volume of the steel 5711. Collectors also value that Patek did not dilute it: eight years on, there is still only one 5740 reference.

What is the hardest Patek to get?

At retail, the 5740 is on the short list with the 5811/1G, the 5726/1A-014 and the 5167A. All are allocated rather than sold, and the 5740's higher price does not make it easier: boutiques offer it to clients who have bought several less-demanded pieces first. On the secondary market it is straightforward to find at a price. Our 5711 guide explains how allocation works for the Nautilus range.

5740 vs 5726 vs 5712: which calendar Nautilus?

5740/1G 5726/1A 5712
Calendar Perpetual, with leap year Annual, corrected each March Pointer date only
Moon phase Yes Yes Yes
Thickness 8.42 mm 11.3 mm About 8.5 mm
Metal White gold only Steel Steel (discontinued 2025), rose gold, white gold
Retail, 2026 Low six figures High US$50,000s US$60,000s to 90,000 for gold

The 5740 is the complete calendar; the 5726 gives most of the display for well under half the money; the 5712 is the moon phase without the calendar. Our 5726 guide and 5712 guide cover the other two.

Is the Patek 5740 a good investment?

It has fallen a long way from its early-2022 peak, when secondary asks briefly cleared US$400,000, to the current US$200,000 to 300,000 range, which is the pattern across most steel and gold Nautilus references bought during that period. Against that, it sells at roughly one and a quarter to two times its own retail price, a smaller multiple than the steel 5711 ever carried and one that has held reasonably steady through 2025 and 2026 rather than falling further. Being the only perpetual calendar Nautilus and made in a single metal gives it a narrower, more collector-driven buyer base than the steel sports references, which tends to smooth out speculative swings. Buy it for the complication and the case, not as a short-term trade; if resale matters, ask for a written cash-buy assessment for the specific reference and set before you commit.

How does the Nautilus 5740 wear?

The 40 mm case and integrated bracelet follow the same lines as every other Nautilus, so on the wrist it reads as a sports watch rather than a dress complication, which is the point of the design. At 8.42 mm it sits notably flatter than the 5726 and slips under a cuff the way a perpetual calendar rarely does. The white gold bracelet is heavier than the steel bracelet on a 5711 or 5726, and that weight is the clearest physical sign that this is Patek's most expensive Nautilus rather than its most common one. The three subdials at 3, 6 and 9 keep the dial legible despite the added functions, and the moon phase window at 6 does not crowd the date. Wrists from about 15 cm carry the 5740 well; the case does not run large by Nautilus standards, so sizing decisions come down to the same reference points as the 5711 and 5726.

Buying a 5740: 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, so a 2019 5740 without papers stays without papers until 2029. Our serial number check guide explains the numbers.
  • Calendar setting. Have the seller advance the date, day, month, leap-year cycle and moon with the case correctors and confirm each jumps cleanly. Never set a perpetual calendar between 8 pm and 4 am.
  • Bracelet. White gold links wear faster than steel; check for stretch, clasp wear and mismatched link finishing that suggests replaced links.
  • Case finishing. Sharp transitions between the brushed bezel top and polished chamfers; softened edges mean polishing.
  • Tiffany claims. A Tiffany stamp adds a large premium, so verify it against the Certificate of Origin, which names the retailer; a stamp without matching paperwork is not worth the premium.
  • Price against the band. A 5740 offered well under the market is the single most reliable warning sign.
