One of the most technically impressive and visually striking references in the Nautilus collection, the 5990/1R combines a dual time zone function with a flyback chronograph, all housed in a bold 18k rose gold case and bracelet. The sunburst blue dial with horizontal embossing offers remarkable contrast and depth, shifting beautifully with the light. This example was sold in 2022 and comes as a complete full set from the original owner. The watch is unpolished and remains in excellent condition, showing only light signs of careful wear. It was recently serviced and runs flawlessly. A top-tier modern Patek Philippe with strong wrist presence, everyday functionality, and collectible appeal.
