Overview
Master the art of sophisticated functionality with the Patek Philippe Nautilus Annual Calendar Reference 5726A-001. A perfect fusion of the iconic Nautilus sport-chic aesthetic and one of Patek Philippe’s most practical complications, this new 2026 model, available at Cest Watches, is a true modern classic. Crafted in high-performance stainless steel and uniquely paired with a hand-stitched alligator strap, the 5726A-001 offers a complete annual calendar and moon phase display in a robust yet refined silhouette.

A Dial of Depth & Exceptional Clarity
The black-gradated dial is the hallmark of this reference, featuring the iconic horizontal embossing and a subtle transition from charcoal grey to deep black at the periphery. The dial provides a wealth of information with remarkable clarity: day and month apertures at 12 o’clock, a date window at 6 o’clock, and a sub-dial at 6 o’clock that houses a moon phase display and a 24-hour indicator. The white gold applied hour markers and hands are filled with a luminescent coating, ensuring perfect legibility and a harmonious, luxurious aesthetic.

The Icon of Versatility: 40.5mm Stainless Steel & Leather
The 40.5mm case is expertly crafted from high-performance stainless steel, featuring the signature porthole-inspired silhouette and rounded octagonal bezel with a sophisticated blend of satin-brushed and polished finishes. In a departure from the traditional integrated steel bracelet, the 5726A-001 is presented on a matt black alligator leather strap, which adds a layer of formal elegance and makes the watch exceptionally versatile for both casual and professional settings. The strap is secured by a Nautilus fold-over clasp in stainless steel.

Mechanical Excellence: Calibre 324 S QA LU 24H/303
At the heart of this timepiece is the self-winding Patek Philippe Calibre 324 S QA LU 24H/303, a movement that represents the pinnacle of the brand’s technical expertise. The annual calendar complication is ingeniously designed to automatically distinguish between months with 30 and 31 days, requiring only one adjustment per year on March 1st. Visible through the sapphire crystal case back, the movement features a 21k gold central rotor and meticulous hand-finishing, proudly bearing the prestigious Patek Philippe Seal.
