Patek Philippe Nautilus Annual Calendar Moon Phases - 40.5 mm - Steel - Blue Dial - 5726/1A-014

Patek Philippe Nautilus Annual Calendar – 40.5mm Stainless Steel

The Patek Philippe Nautilus Annual Calendar (Ref. 5726/1A) blends the iconic sport-luxury design of the Nautilus collection with the technical brilliance of Patek Philippe’s annual calendar complication. Encased in a 40.5 mm stainless steel case measuring 11.3 mm in thickness, the watch maintains the Nautilus’ signature porthole-inspired design while offering a refined, modern silhouette.

The blue dial with a black gradation radiates depth and sophistication, featuring gold applied hour markers coated with luminescent material for legibility in any lighting condition. The watch is powered by the Caliber 324 S QA LU 24H self-winding movement, which drives an annual calendar displaying the day, date, month, and moon phase, alongside a 24-hour indicator. The movement offers a power reserve of approximately 35–45 hours, visible through the sapphire-crystal case back.

Completing the look is a stainless steel bracelet with a Nautilus fold-over clasp, providing both comfort and security. With water resistance up to 120 meters, this model is as robust as it is elegant—perfectly suited for both formal occasions and everyday wear.
