Patek Philippe discontinued the stainless steel Nautilus Travel Time Chronograph 5990/1A-001 in 2022. Just months later, a new stainless steel model returned in the form of the ref. 5990/1A-011—a refined evolution of the ultimate traveler's Nautilus. Blending a flyback chronograph with dual time zone functionality, this is horological sophistication engineered for the global elite.

The sunburst blue dial with black-gradient rim is a visual masterpiece, horizontally embossed and framed by gold applied markers. Beneath the sapphire crystal beats the caliber CH 28-520 C FUS, a self-winding movement with Gyromax balance and Spiromax balance spring, delivering precision across two time zones with day/night indicators for both.

This watch presents in excellent condition, with little to no signs of wear. Please reference the photos for the most accurate representation of the condition of the watch. We do our best to emphasize, rather than diminish any flaws through our macro photography.
