The Patek Philippe Nautilus 5726 is the annual calendar Nautilus: a 40.5 mm steel case with day, date and month in three apertures, a moon phase and a 24-hour dial, on a calendar mechanism that only needs correcting once a year. Introduced in 2010 on a strap and in 2012 on the bracelet, it is the most affordable complicated Nautilus still in production and, since the 5711 and steel 5712 were retired, the steel Nautilus most people can realistically be offered. This guide covers every 5726 reference, 2026 prices, whether it is discontinued, how it compares with the 5712 and 5980, and what to check before buying. Bizak & Co. sources 5726 references to order; the Nautilus collection lists the configurations we can seek.

The 5726 is the Nautilus that gives you the most information for the money: five calendar and astronomical displays on a dial that still reads as a Nautilus, in a case only 3 mm thicker than a 5711.
Every Nautilus 5726 reference
| Reference | Bracelet or strap | Dial | Status |
|---|---|---|---|
| 5726A-001 | Black composite strap | Black-grey gradient | 2010 onward, in production |
| 5726/1A-001 | Steel bracelet | Black-grey gradient | 2012 to 2019, discontinued |
| 5726/1A-010 | Steel bracelet | White | 2019 onward; check the current catalogue |
| 5726/1A-014 | Steel bracelet | Blue sunburst | 2019 onward, in production |
The blue 5726/1A-014 is the reference most buyers search for and the one Patek shows on its own site alongside the strap 5726A-001. Our reference numbers guide explains the "/1" bracelet code and the dial suffixes.
Is the Patek 5726 discontinued?
No. The blue-dial 5726/1A-014 and the strap 5726A-001 are both in Patek's 2026 catalogue. The black-dial bracelet 5726/1A-001 was replaced by the blue and white dials in 2019, and the white 5726/1A-010 has appeared and disappeared from retailer listings, so confirm its status with the boutique if that is the one you want. The 5726 is now the only steel Nautilus with a calendar complication still being made, which is why demand for it rose after the steel 5712 left the catalogue in early 2025.
How much is a Patek 5726? Retail and secondary prices in 2026
- 5726/1A-014 (steel bracelet, blue). US retail in the high US$50,000s to around US$60,000 in 2026. Secondary asks for unworn full sets have generally been in the US$85,000 to 110,000 range in 2025 and 2026, a smaller premium than the 5711 or 5712 carry.
- 5726A-001 (strap, black). Retail around US$50,000. Secondary asks roughly US$60,000 to 80,000; the strap watch is the most obtainable 5726 and the closest to retail.
- 5726/1A-001 (bracelet, black, discontinued). Secondary asks broadly in the same band as the blue watch, with early full sets at the lower end.
- 5726/1A-010 (bracelet, white). Secondary asks similar to the blue dial; fewer examples.
These bands describe what we saw in 2025 and 2026 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.
Is the Patek 5726 a good investment?
It has been the steadiest of the steel Nautilus references rather than the most explosive. Because it is still in production, its secondary premium is about 1.5 to 2 times retail rather than the 3 to 5 times the discontinued 5711 and 5712 reached, and it fell less in the 2022 to 2023 correction for the same reason. That makes it a better watch to buy at secondary prices if you intend to wear it, and a worse one if you are hoping for a discontinuation windfall. If resale matters, ask for a written cash-buy assessment for the same watch and condition before you commit.
5726 vs 5712 vs 5980: which complicated Nautilus?
| 5726 | 5712 | 5980 | |
|---|---|---|---|
| Complication | Annual calendar, moon phase, 24 h | Date, moon phase, power reserve | Flyback chronograph |
| Case | 40.5 mm, 11.3 mm thick | 40 mm, 8.5 mm thick | 40.5 mm, 12.2 mm thick |
| Steel in production | Yes | No, discontinued early 2025 | No, discontinued 2014 |
| Steel secondary, 2026 | US$85,000 to 110,000 | US$150,000 to 250,000 | Six figures |
The 5726 is the value choice among complicated steel Nautilus watches by a wide margin. The 5712 is thinner and rarer; the 5980 is the chronograph. Our 5712 guide and 5980 guide cover the other two.
Who wears a Patek Philippe 5726?
The 5726 is the Nautilus that experienced collectors choose when they want a complication they will use every day rather than a chronograph they will rarely start, and it has become the steel Nautilus boutiques are most likely to offer a client who has been waiting for a 5711 or 5811. We do not track celebrity wrists; the watch's appeal is that it does not need one.
Buying a 5726: 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. Our serial number check guide explains the numbers.
- Calendar correction. Have the seller set the day, date, month and moon with the correctors and confirm each aperture jumps cleanly; never set the calendar between 8 pm and 4 am.
- Dial version. Black-grey gradient means an -001; blue sunburst means -014; white means -010. Bracelet references start "5726/1A".
- Case finishing. Sharp transitions between brushed and polished surfaces; rounded edges mean polishing.
- Bracelet. Count the links and check for stretch on early examples.
- Price against the band. A 5726/1A-014 offered well under the market is the single most reliable warning sign.
