Overview
Experience the ultimate fusion of sports elegance and high-complication horology with the Patek Philippe Nautilus Perpetual Calendar Reference 5740/1G-001. As the first Grand Complication in the Nautilus collection, this new 2026 model, available at Cest Watches, represents a historic milestone for the brand. Crafted in solid 18k white gold and featuring a stunning blue sunburst dial, the 5740/1G-001 is a masterpiece of technical ingenuity, offering a complete perpetual calendar in a remarkably slim and wearable silhouette.

A Dial of Technical Mastery & Radiant Blue
The blue sunburst dial is the hallmark of this reference, featuring the iconic horizontal embossing and a vibrant hue that shifts beautifully in the light. Despite its complexity, the dial maintains exceptional legibility through three elegantly arranged sub-dials: day and 24-hour indication at 9 o’clock, month and leap year cycle at 3 o’clock, and date and moon phases at 6 o’clock. The 18k white gold applied hour markers and hands are filled with a luminescent coating, ensuring a harmonious and luxurious aesthetic that perfectly complements the white gold case.

The Ultra-Thin Grand Complication: White Gold & 8.42mm
The 40mm case is expertly crafted from solid 18k white gold, featuring the signature porthole-inspired silhouette and rounded octagonal bezel. Remarkably, despite housing a complex perpetual calendar movement, the 5740/1G-001 maintains an ultra-thin profile of just 8.42 mm, making it one of the slimmest perpetual calendars in the world. The integrated white gold bracelet is equipped with the new Patek Philippe fold-over clasp with an integrated adjustment system, ensuring unparalleled comfort and a secure fit.

Mechanical Excellence: Calibre 240 Q
At the heart of this masterpiece is the self-winding Patek Philippe Calibre 240 Q, an ultra-thin movement that represents the pinnacle of the brand’s engineering. This high-performance caliber features a 22k gold off-center mini-rotor, which allows for the watch’s incredibly slim profile while providing efficient winding. Visible through the sapphire crystal case back, the movement showcases the meticulous hand-finishing, including circular graining and Côtes de Genève, and proudly bears the prestigious Patek Philippe Seal.
