Patek Philippe Nautilus Moonphase 5712/1A-001
Known as The steel Nautilus Moonphase, or just "the 5712"
The 5712/1A-001 is the steel Nautilus that stopped being a sports watch and started being a complication piece. Patek introduced it in 2006, the year the Nautilus turned 30, as the successor to the old 3712. The layout is the whole point: small seconds with a moon phase parked at 7 o'clock, a pointer power reserve sweeping across roughly 10 to 12 o'clock, and a pointer date at 4 o'clock. Nothing is symmetrical, and that is deliberate. Most steel Pateks with this much going on look busy. This one looks calm because the sub-dials are spread across the horizontally grooved dial the way the moon actually moves across a sky, off to one side. It runs the caliber 240 PS IRM C LU, the ultra-thin micro-rotor movement Patek has leaned on for decades, in a 40mm case that wears flatter than the number suggests. Patek discontinued it on February 1, 2025, after a nineteen-year run. That end date is now part of the story every time one crosses our counter on 47th Street.
Produced: 2006 to 2025. Introduced for the Nautilus 30th anniversary as the replacement for the 3712/1A, which had a short two-year run from 2005 to 2006. Patek officially discontinued the 5712/1A-001 on February 1, 2025.

Market & Value
This watch has lived two lives on the pricing side. During the 2021 to 2022 mania it traded well into the low-to-mid $100,000s and touched higher on the right examples. It came back down hard with the rest of the steel Patek market. As of mid-2026 the common full-set 5712/1A-001 sits around the low-$90,000s on the trade, with clean retail asks and stronger examples running past $110,000. Range across the open market is wide, roughly $80,000 up past $200,000, and that spread is almost entirely about three things: dial variant, papers, and the stamp on the dial. A standard black-blue example with box and papers is one number. A Tiffany & Co. co-signed 5712/1A is a completely different animal and trades at a heavy premium. Original MSRP at discontinuation was well under half of where the secondary market sits, which is exactly why these never touched retail shelves at sticker for most of their life. The discontinuation put a floor under collector interest because the supply is now fixed. We watch this reference weekly. When we write a check on one, condition of the bracelet, presence of the original certificate of origin, and whether the dial is standard or co-signed drive the offer more than the year.
What to Know Before You Buy
First, buy the paper. A 5712 without its Patek certificate of origin is worth real money less than one with a matched full set, and on a watch at this price that gap is not small. Second, understand the dial. The standard 5712/1A-001 is black-blue gradient. A Tiffany & Co. stamped dial is its own market and commands a large premium, so verify the stamp is factory and matches the papers rather than a later-added dial. Third, the caliber 240 PS IRM C LU is thin and proven, but it is a Patek, so service means Patek pricing and Patek timelines; ask when it was last serviced and by whom. Fourth, check the bracelet. Nautilus bracelets stretch with wear and the finish shows every polish, so an over-polished case or a loose bracelet drops the value. Fifth, do not confuse this with the 5711 time-only Nautilus or the 5726 Annual Calendar; the 5712 is the moon phase and power reserve piece with the asymmetric dial, and it is the one that got discontinued in 2025. Verify the reference on the caseback and papers, not just the look.

We buy and sell the 5712/1A-001 at Ultimate Watch, 19 W 47th Street. This is a reference we know at the counter, not from a chart. If you own one and want a real number, bring it in with the box and certificate of origin and we will make you an offer the same day; if the papers are missing we can still buy it, the price just reflects that. If you are looking to acquire one, tell us whether you want a standard black-blue dial or you are hunting a Tiffany-stamped example, because those are two different searches and two different budgets. Either way, come to the store, call us, or request an offer and we will handle it directly.
