The Patek Philippe Nautilus reference 5726/1A-010 is a luxury sports watch featuring a 40.5mm stainless steel case with the collection’s signature rounded octagonal bezel and porthole-inspired design. This specific iteration, produced between 2012 and 2019, is distinguished by its silvery-white dial adorned with the classic horizontal Nautilus embossing. The watch is constructed with a screw-down crown and a sapphire crystal caseback, providing water resistance up to 120 meters. It is paired with an integrated stainless steel bracelet that features a mix of brushed and polished finishes and a patented fold-over clasp.
The timepiece is powered by the self-winding caliber 324 S QA LU 24H/303, a sophisticated in-house movement composed of 347 parts with a 21k gold rotor. It features a useful annual calendar complication that automatically accounts for months with 30 and 31 days, requiring only one manual adjustment per year at the end of February. The dial displays the day and month through side-by-side apertures at 12 o’clock, while the date is positioned at 6 o’clock. Additionally, the watch includes a moon-phase indicator and a 24-hour subdial, both integrated at the 6 o’clock position for a balanced and symmetrical layout.
General reviews of the 5726/1A-010 often praise its perfect dial symmetry and the practical utility of its complications compared to the time-only models. While it is noted for being thicker than the 5711 due to the annual calendar module, enthusiasts frequently highlight its impressive wearability and versatility as an elegant everyday watch. Though the white dial was initially considered less popular among collectors than the gradient blue or black versions, it has gained appreciation for its clean, contemporary aesthetic and its unique position as the first Nautilus to combine a steel case with an annual calendar. Some critics occasionally note the short power reserve of approximately 45 hours relative to modern standards.
