Patek Philippe Nautilus 5990/1A-011

About This Watch

The Patek Philippe Nautilus 5990/1A-011 combines a flyback chronograph with a dual time zone display, making it the most functional Nautilus in the current collection. The 5990 evolved from the 5980 chronograph by adding a second time zone displayed via a subsidiary dial at 6 o'clock, accompanied by a day/night indicator. The flyback chronograph function remains, operated by the pushers integrated into the left side of the case. The 2023 update brought the green-black gradient dial that has become a Nautilus signature, replacing the previous blue-black iteration. The caliber CH 28-520 C FUS is a masterwork of compact mechanical engineering, integrating chronograph, dual time zone, and date complications in a movement thin enough to maintain the Nautilus's sleek profile. The column wheel chronograph mechanism features a disc clutch for smooth start-stop operation, and the flyback function allows instant chronograph reset and restart. At 40.5mm, the case dimensions remain true to the Nautilus design language while accommodating the additional functionality. This reference is particularly suited to global travelers who need chronograph functionality alongside dual time zone tracking, all wrapped in the most prestigious integrated-bracelet sports watch design ever created.
