Patek Philippe Nautilus Travel Time Chronograph – Stainless Steel Ref. 5990/1A-001

Patek Philippe Nautilus Travel Time Chronograph – Stainless Steel Ref. 5990/1A-001

A masterpiece of modern complication within the unmistakable form of the Nautilus, the Patek Philippe Ref. 5990/1A-001 blends contemporary functionality with iconic sport-luxury design. Crafted entirely in stainless steel, this reference showcases Patek’s ingenuity in combining a flyback chronograph with a dual-time zone mechanism, all housed within the elegant yet robust 40.5mm Nautilus case.

Launched in 2014, the 5990/1A immediately became a flagship in the stainless steel Nautilus family — prized for its complex mechanical heart, intuitive functionality, and subtle design cues. The horizontally embossed gradient gray dial shifts from a radiant navy to near black at the edges, featuring dual apertures at 9 o’clock and 3 o’clock for home and local day/night indication, along with a skeletonized local hour hand for seamless time zone transitions.

At 6 o’clock sits a 60-minute chronograph counter, part of the flyback chronograph function powered by the Caliber CH 28-520 C FUS. This automatic movement unites a column wheel chronograph with a vertical clutch and patented Time Zone mechanism, viewable through the sapphire caseback.

With a 120-meter water resistance rating, integrated stainless steel bracelet, and supreme finishing throughout, the Nautilus 5990/1A-001 is a connoisseur’s sports watch — offering true travel utility and haute horlogerie pedigree in a single, seamless package.
