Patek Philippe Nautilus Moon Phase 5712/1R-001

The Patek Philippe Nautilus Moon Phase ref. 5712/1R-001 is the 40mm rose gold version of the Nautilus with moon phases, small seconds and a power reserve indicator, powered by the automatic micro-rotor Calibre 240 PS IRM C LU. Cazador has no verified price observations yet. Its differential: the asymmetrical layout of the complications on the dial, unusual within Patek Philippe's catalog.

History

The Nautilus was born in 1976 under Gérald Genta as Patek Philippe's first luxury sports watch in steel, defined by its octagonal bezel and the porthole-inspired side 'ears.' For decades the collection stayed focused on time-only or calendar models, until 2006, when Patek Philippe introduced the 5712 as the first Nautilus execution with moon phases.

Reference 5712/1R-001 carries that complication into an 18k rose gold case measuring 40mm across and just 8.52mm thick, with an integrated bracelet in the same metal and a fold-over clasp with a safety catch. The dial, with a graduated brown finish and a darker outer ring, spreads its indications asymmetrically: the moon phase and power reserve indicator share a double sub-dial near 12 o'clock, while small seconds sits in an independent position — an unconventional layout within the Geneva manufacture's catalog.

Inside runs the Calibre 240 PS IRM C LU, an automatic micro-rotor movement — a peripheral oscillating weight in 22k gold that keeps the overall caliber thickness to just 3.99mm across a 31mm diameter — built from 252 components and 29 jewels, with a Gyromax balance oscillating at 21,600 semi-oscillations per hour. Power reserve runs between a minimum of 38 and a maximum of 48 hours.

The date is set via a corrector, since the Nautilus Moon Phase forgoes a quick-set crown position for that function, a design choice consistent with the line's understated approach to complications. Rated to 30 meters of water resistance, this execution isn't built for diving — it's a dress Nautilus with an astronomical complication. As of this writing, the reference remains in Patek Philippe's current catalog.

Frequently asked questions

How much does a Patek Philippe Nautilus Moon Phase 5712/1R-001 cost?

Cazador has no verified price observations for this reference yet. We'll publish a range once sufficient sourced market data exists.

What complications does the 5712/1R-001 have?

Moon phases, small seconds and a power reserve indicator, alongside hours, minutes and a corrector-set date.

What is the Calibre 240 PS IRM C LU?

It's an automatic micro-rotor movement, with a peripheral 22k gold oscillating weight that allows a total thickness of just 3.99mm despite integrating several complications.

Is the bracelet on the 5712/1R-001 solid gold?

Yes, the bracelet is integrated and made from the same 18k rose gold as the case, with a fold-over clasp and safety catch.

Can the Nautilus Moon Phase be worn swimming?

It's rated to 30 meters of water resistance, enough for splashes and rain, but it isn't built for swimming or diving.

How much power reserve does this reference have?

Between a minimum of 38 and a maximum of 48 hours, depending on the micro-rotor's wind state at the time the indicator is checked.

Is the 5712/1R-001 still in production?

Based on the catalog data we work from, the reference remains in active production within the Nautilus collection.
