Nautilus 5990/1R-001

Patek Philippe Nautilus 5990/1R-001

The Patek Philippe Nautilus Travel Time Chronograph – Ref. 5990/1R-001 unites two of the manufacture’s most practical complications — flyback chronograph and dual time-zone (Travel Time) — within the unmistakable porthole-inspired Nautilus architecture. Presented in full 18K rose gold, this 40.5 mm reference pairs sport-elegance with high complication mastery.

The rose gold case measures 12.53 mm in thickness and features the Nautilus’ signature alternating satin-brushed and polished finishes. Integrated pushers at 9 o’clock adjust the local hour forward or backward in one-hour increments, while a screw-down crown and sapphire crystals (front and exhibition caseback) ensure structural integrity and 30 meters of water resistance, supported by double O-ring sealing on the crown and pushers.

The captivating sunburst blue dial with horizontal embossing is equipped with applied luminescent baton markers and matching hands. The layout includes a skeletonized home-time hand, solid local hour hand, day/night indicators for both time zones, pointer date synchronized to local time, central chronograph seconds, and a 60-minute counter — all harmonized for intuitive legibility.

At its core beats the in-house Calibre CH 28-520 C FUS, a self-winding movement composed of 370 components and 34 jewels. Measuring 31 mm in diameter and 6.95 mm thick, it operates at 28,800 vibrations per hour (4 Hz) and is fitted with a Spiromax® balance spring and 21K gold rotor. Certified under the Patek Philippe Seal, it delivers a power reserve of 45–55 hours, ensuring precision and finishing to the highest horological standards.

Mounted on a solid rose gold Nautilus bracelet with patented fold-over clasp, the 5990/1R-001 represents a rare full-rose-gold configuration of one of Patek Philippe’s most mechanically versatile Nautilus references.
