Patek Philippe · Family: Nautilus
The Patek Philippe Nautilus Travel Time Chronograph 5990/1A-001 is a 40.5mm steel watch with the Nautilus's signature "cushion" case shape, combining a flyback chronograph with a dual-time-zone (Travel Time) function and day/night indicators. It runs the in-house automatic Caliber CH 28-520 C FUS with 55 hours of power reserve. Cazador has no verified price observations yet (n=0). Its standout detail: introduced in 2014, it's the only Nautilus reference that combines a chronograph and dual time zone in a single caliber.

The Nautilus was born in 1976, also designed by Gérald Genta, as Patek Philippe's answer to the luxury steel sports-watch phenomenon he himself had kicked off with Audemars Piguet's Royal Oak four years earlier. Its "cushion" case with two visible side "ears," inspired by a ship's porthole, became its defining trait.
For much of its history, the Nautilus remained a three-hand line or, at most, a simple chronograph. The Travel Time complication — a dual time zone with independent day/night indicators for each zone, adjusted via two pushers on the case — arrived in the family as a three-hand model in 2006 (ref. 5164) and, as a flyback chronograph, with this reference 5990/1A in 2014.
The 5990/1A-001 combines both complications in Caliber CH 28-520 C FUS, an in-house automatic movement with a central rotor that, alongside the chronograph and Travel Time functions, includes a date set via the crown itself, with no additional pusher. To date, it remains the only reference in Nautilus history to combine a chronograph and dual time zone in a single caliber.
This is the second Nautilus reference Cazador adds, alongside the three-hand version already in the catalog.
