The Nautilus was first produced in 1976, almost forty years ago. The first chronograph Nautilus came in 2006. And now, Patek Philippe has a introduced for the first time, a Nautilus the combines the chronograph and dual time functions.

The Nautilus Chronograph Travel Time 5990A is presented in a 40.5 mm stainless steel case with alternating satin finished and polished surfaces. The dial is black/grey, with a horizontal guilloche pattern. The hour and minute hands have white luminous material, as do the applied indexes that mark all but the 12 and 6 o’clock hours.

The second time zone is indicated by a skeletonized central hand. Uniquely, the second time zone (or local time zone) can be adjusted by the buttons at 9 o’clock. Apertures at 3 and 9 o’clock indicate day/night in the home and local time zones. At 6 o’clock is a 60-minute chronograph counter that is operated by the buttons on the right side of the case. Chronograph seconds are indicated by the sweeping central hand. The date is indicated via a subdial at 12 o’clock, controlled via the crown.

Powering the new Nautilus is a self-winding CH 28-520 C FUS caliber with Gryomax balance and silicon Spriomax hairspring. It runs at 4Hz and has 55-hour maximum power reserve.
