Patek Philippe Nautilus 5726/1A-010

Patek Philippe Nautilus Annual Calendar reference 5726/1A-010, a masterpiece that seamlessly fuses the ultimate luxury sports watch aesthetic with sophisticated horological complications. Encased in a robust 40.5mm stainless steel case, this timepiece proudly displays Gérald Genta's legendary porthole-inspired design, complete with a satin-brushed and polished rounded octagonal bezel and prominent lateral "wings". This specific version is defined by its clean, striking silvery-white dial, which features the Nautilus collection's signature horizontal embossed pattern, framed by black-accented applied white gold hour markers and matching baton hands coated in luminescent material. The dial showcases a masterfully arranged, highly legible annual calendar complication that only requires a single correction per year; it displays the day of the week and month through two inline apertures side-by-side at 12 o’clock, a date window at 6 o'clock, and a dual-purpose sub-dial at 6 o'clock tracking a 24-hour day/night indicator alongside a precise moon phase display. Driven by the self-winding, high-performance in-house Calibre 324 S QA LU 24H/303 movement, the watch offers a 45-hour power reserve and can be admired through an exhibition sapphire crystal caseback.
