The Patek Philippe Nautilus 5711/1A-018 is a 40mm stainless steel automatic sports watch that sits at the absolute apex of the Nautilus family — a lineage Gerald Genta designed in 1976 and one whose 5711 reference Patek Philippe announced would leave the collection in 2022. Released in 2021 to commemorate 170 years of partnership between Patek Philippe and Tiffany & Co., this reference was produced in a hard cap of exactly 170 examples, each bearing the dual signatures of both maisons on its unmistakable Tiffany Blue dial.

What the specs mean on the wrist
The 40mm stainless steel case is the Goldilocks dimension that made the 5711 universally wearable — substantial enough to read as a serious watch, restrained enough to slide under a dress-shirt cuff without drama. The integrated bracelet, horizontally embossed dial, and sapphire-backed porthole case are pure Genta DNA, unchanged in their essential proportions since 1976. In steel rather than precious metal, the 5711 always carried the tension of an accessible material housing a decidedly inaccessible price, and the 1A-018 amplifies that tension to its logical extreme. On the wrist it wears exactly as any 5711 does — balanced, flat, immediately comfortable — with the Tiffany Blue dial providing a color that shifts from robin's-egg bright in daylight to something closer to deep cerulean under evening light.
The automatic movement inside is Patek Philippe's caliber 26-330 S C, a manufacture movement with a date complication, and the completed watch bears the Patek Philippe Seal — every bridge, rotor, and wheel decorated and beveled to a level you can only appreciate properly under a loupe. The movement’s current performance and service needs depend on the condition and maintenance history of the individual watch; the reference specification does not establish either. What you are not buying this watch for is complication count; you are buying it because production was limited to 170 watches, and its dial carries the names of two institutions that have defined luxury for the better part of two centuries.
The dealer’s take
The 5711/1A-018 combines the Nautilus design with a limited anniversary edition and a distinctive dual-signed dial. For a specific example, assess condition, provenance and accompanying documents separately. A claim that a watch is unworn or comes as a full set needs supporting photos and an itemized description. Collectors may also compare other Nautilus references or watches from different makers, depending on what they want to own.
From a collecting standpoint, the 5711/1A-018 brings together a discontinued reference, a production cap tied to the 170-year partnership, and Tiffany & Co. as a co-signer. Those historical features do not establish a future selling price or how quickly a watch could be resold. Condition, provenance and the included set should be checked for the individual example; none guarantees a financial return.
What to check before you buy a Nautilus
- Dual-Signature Dial Authenticity: On the genuine 5711/1A-018, both the Patek Philippe signature and the Tiffany & Co. signature appear on the dial in their correct typefaces, positions, and relative weights. Under magnification, the printing should be razor-sharp with no bleed or inconsistency. Any example where the Tiffany signature looks added, different in finish from the Patek text, or inconsistent with documented references should be rejected immediately.
- Serial Numbers and Provenance: Ask for the movement, case and reference numbers and check them against the original Certificate of Origin and any service records supplied. Matching numbers alone do not complete an authentication assessment. Agree on a specialist inspection of the actual watch before purchase; have any case opening performed by a qualified professional. Our reference numbers guide explains what each part of 5711/1A-018 means and how it differs from the case and movement numbers.
- Box, Papers, and Tiffany & Co. Accompanying Materials: Ask the seller to itemize the original Patek Philippe box, Certificate of Origin and any Tiffany & Co. materials included. An Extract from the Archives is a different document: Patek currently limits requests to watches first sold more than ten years earlier, so it should not be expected for a 2021 release in 2026. Confirm that the papers match the case serial number exactly and that the reference number recorded on the papers corresponds to 5711/1A-018, not a related but different 5711 variant.
- Case and Bracelet Condition on a 'Brand New' Example: Brand new should mean exactly that: no polish marks on the case flanks or bracelet center links, no hairlines on the bezel, crown in pristine condition, and bracelet clasp with no compression wear. On a watch of this value, even micro-level handling marks matter at resale. Inspect the case and bracelet under raking light at multiple angles. Movement finishing visible through the caseback does not by itself establish that the watch is unworn.
Who the 5711/1A-018 is for
The 5711/1A-018 is for the collector who has moved past asking whether a watch is a good value in any conventional sense and is instead asking whether this is the right artifact at this moment. It suits someone with a mature Patek collection who understands the brand's history, appreciates the century-and-a-half relationship between Geneva and Tiffany's Fifth Avenue, and wants a piece that is genuinely, documentably finite. It is not a watch for the enthusiast exploring the Nautilus family for the first time, nor for anyone who needs liquidity flexibility — at this price level, buyers should be prepared to hold the piece on their own terms rather than the market's.
Compare the Tiffany Nautilus with two related references
The 5711/1A-018 is the choice to research if the Tiffany Blue dial and anniversary edition are central to your interest. For a different dial within the steel 5711 family, compare the olive-green 5711/1A-014. For a larger case in precious metal, compare the white-gold 5811/1G-001.
| Reference | Factory configuration | What to compare |
|---|---|---|
| 5711/1A-018 Tiffany Blue Nautilus | 40 mm steel case and steel bracelet; Tiffany Blue dial with Patek Philippe and Tiffany & Co. signatures. Edition of 170 watches. | The exact reference reviewed here: focus on its anniversary identity and the documentation of the individual watch offered. |
| 5711/1A-014 olive-green Nautilus | Steel case and bracelet with an olive-green sunburst dial; self-winding caliber 26-330 S C. | A related steel 5711 when you prefer the olive-green finish to the Tiffany Blue anniversary dial. |
| 5811/1G-001 white-gold Nautilus | 41 mm white-gold case and bracelet; blue sunburst dial shading to black at the edge, with a lockable bracelet adjustment system. | A different case size, material and clasp to consider if wearing fit matters more to you than the Tiffany edition. |

The Bizak & Co. verdict
The Nautilus 5711/1A-018 is not a watch you evaluate by its movement specifications or its wrist comfort, though both are genuinely excellent. You evaluate it by what it represents: the convergence of a discontinued case reference, a production run of exactly 170 pieces tied to a 170-year partnership, and two of the most recognizable names in the luxury world sharing a single dial. Those are documented facts about the 2021 anniversary edition; they do not establish what Patek Philippe may release in the future. In that sense, the watch functions as a primary document of a specific moment in horological and retail history.
An asking price is a seller’s offer, not evidence of a completed sale. Evaluate the particular watch and its documentation before comparing prices. The anniversary edition is one reason to consider this reference, but the decision should also account for the actual watch’s condition, documentation and quoted terms. Contact Bizak & Co. directly to discuss this piece — transactions of this nature require a conversation, not a cart.
FAQ: 5711/1A-018
Why does the Patek Philippe Nautilus 5711/1A-018 cost so much?
The reference combines a discontinued 5711 design, an edition of 170 watches and the Patek Philippe and Tiffany & Co. signatures. Those features distinguish it from other Nautilus references, but do not establish a current market price. Compare dated offers for matching examples, their condition and documentation; an asking price alone is not evidence of a completed sale.
How does the 5711/1A-018 wear on the wrist? Is 40mm too large or too small?
The 5711's 40mm case has always been one of its defining strengths — it sits flat, wears closer to a 38mm in feel because of the integrated bracelet, and works on a wide range of wrist sizes. This is not a watch that overwhelms a smaller wrist or disappears on a larger one. The Tiffany Blue dial reads differently in different light conditions, which adds to its wearability rather than limiting it.
What movement is inside the Patek Philippe Nautilus 5711/1A-018?
The 5711/1A-018 is powered by Patek Philippe's caliber 26-330 S C, an in-house automatic manufacture movement with a date complication. The watch bears the Patek Philippe Seal. It is the same caliber used across the later production run of the 5711 family — a proven, well-regulated movement with the finishing standards you expect from Patek at this tier.
Is the Nautilus 5711/1A-018 a good investment?
A future return cannot be guaranteed. The limited edition and dual signatures may matter to collectors, but they do not establish future value or resale timing. Prices can fall, and ownership or selling costs affect any eventual result. Verify the offered watch’s condition, provenance and included set rather than treating rarity or a full-set description as a return guarantee.
