209 Patek Philippe New Old Stock, very rare and attractive, Nautilus, date, moon phases, power reserve, automatic wristwatch in steel with certificate of origin, single sealed, reference 3712/1A.

Estimate: € 120.000 –⁠ 240.000

Among the rarest and most coveted expressions of Gérald Genta’s legendary Nautilus design, the Patek Philippe reference 3712/1A occupies a place of reverence in the canon of contemporary watch collecting. Introduced in 2005 and discontinued less than a year later, the 3712/1A was produced in extremely limited numbers, with estimates suggesting as a few hundred examples left the manufacture. It was the first Nautilus to combine complications: a power reserve, date, moonphase, and small seconds, into a single, asymmetrically poetic composition that somehow remains perfectly balanced. Powered by the ultra-thin caliber 240 PS IRM C LU, the model’s designation reveals its mechanical sophistication: petite seconde, indication de réserve de marche, calendrier, and lune. These indicators are laid out across the dial with charming eccentricity, nestled within the signature porthole-inspired case measuring 42mm in diameter. Unlike its successor, the reference 5712, the 3712 features a two-part case with more angular lugs, wider dial ridges, and a highly desirable three-dot power reserve display—a detail treasured by collectors and scholars alike. The example presented here is preserved perfectly: fully factory sealed, untouched since its original purchase. Accompanied by its full complement of accessories, including Certificate of Origin, product literature, presentation wallet, and outer packaging, this is a high-quality watch in every sense. As the final evolution of the original Nautilus before the introduction of the modern 5712, the 3712/1A is a landmark in the ongoing story of Patek Philippe.
