Patek Philippe Nautilus Annual Calendar – Moonphase | Stainless Steel | Black Dial
Reference: 5726A-001 | 2018 Model | Full Set
The Patek Philippe Nautilus Annual Calendar 5726A-001 in stainless steel combines Gérald Genta’s iconic sports-luxury design with one of Patek’s most practical complications. Introduced in 2010, this reference was the first Nautilus to feature an annual calendar and moonphase, offering everyday functionality without compromising elegance. This 2018 full set includes the original Patek Philippe box, certificate of origin, manuals, and setting stylus, making it a complete and collectible package.
The 40.5mm stainless steel case retains the classic Nautilus silhouette with its rounded octagonal bezel, satin-brushed surfaces, and polished accents. Its black horizontally embossed dial transitions to a rich grey toward the edges, creating striking depth and contrast. White gold applied indices with luminescent accents ensure readability, while the annual calendar displays the day, date, and month in harmoniously balanced apertures, accompanied by a moonphase indicator and 24-hour subdial.
At its heart is the Patek Philippe Calibre 324 S QA LU 24H/303, an automatic movement renowned for precision and practicality. The annual calendar requires adjustment only once per year (at the end of February), while the sapphire exhibition caseback reveals Geneva Seal finishing and a 21k gold central rotor.
The watch is presented on a black alligator leather strap with a stainless steel fold-over clasp, offering refined comfort on the wrist.
