Patek Philippe 5990 Nautilus Travel Time Chronograph SS Blue Dial

The Patek Philippe Nautilus Travel Time Chronograph reference 5990/1A‑011, introduced in 2022, represents a rare and compelling fusion of sporty elegance and mechanical sophistication. Housed in a 40.5 mm stainless steel case with the signature porthole‑inspired Nautilus profile, this model is distinguished by its sunburst blue‑gray dial with a black‑gradient rim and horizontally embossed finish. Powered by the in‑house self‑winding calibre CH 28‑520 C FUS, it integrates a flyback chronograph, dual time‑zone Travel Time function, day/night indicators, and a date display synchronized with local time. The movement, visible through the sapphire case back, combines a column‑wheel chronograph with a vertical disk clutch, offering both tradition and innovation. With its 45–55‑hour power reserve, 4 Hz frequency, and Gyromax balance, the calibre exemplifies Patek Philippe’s commitment to performance and precision. Water‑resistant to 30 meters, the watch balances everyday practicality with high horology. The steel bracelet features the patented fold‑over clasp with a lockable micro‑adjustment system, ensuring comfort and security. As a rare steel Nautilus with such a comprehensive suite of complications, the 5990/1A‑011 holds strong appeal for seasoned collectors seeking both technical depth and iconic design.
