Patek Philippe Nautilus Annual Calendar – Stainless Steel with Moon Phase & Black Dial Ref. 5726A-001

Patek Philippe Nautilus Annual Calendar – Stainless Steel with Moon Phase & Black Dial Ref. 5726A-001

A harmonious blend of sport and sophistication, the Patek Philippe Nautilus Ref. 5726A-001 elevates the iconic Gerald Genta design with a full calendar complication and moon phase display. Crafted in stainless steel and paired with a sleek black leather strap, this reference stands as one of the most refined and functional models in the Nautilus collection.

The 40.5mm stainless steel case retains the Nautilus’s signature porthole-inspired architecture, featuring a rounded octagonal bezel with alternating polished and satin-brushed finishes. The embossed black gradient dial — darkening toward the edges — showcases day, date, and month apertures in a clean vertical alignment, while a beautifully detailed moon phase display sits just above the 6 o’clock position, integrated within the 24-hour subdial.

Inside beats the Patek Philippe Caliber 324 S QA LU 24H/303, an automatic movement that powers the annual calendar complication — requiring manual correction only once per year. The moon phase indicator is not only precise but also adds poetic charm to this otherwise sporty timepiece. A sapphire crystal caseback reveals the exquisite finishing and 21k gold rotor within.

Fitted with a matte black alligator leather strap and a deployant clasp, the Nautilus 5726A-001 delivers both elegance and versatility — ideal for collectors seeking daily wearability with calendar complexity.
