With its rounded octagonal bezel, its ingeniously unique porthole-structured case and its dial embossed with horizontal stripes, the Nautilus has perfectly exemplified the elegance of a sports watch since its introduction in 1976.

Still based around the 40.5 mm iconic case design that the Nautilus is known for, the 5990 uses every bit of its distinctive shape to enhance the user interface of the complications. Sure, the chronograph relies on the standard pushers that flank the screw down crown, but the buttons to advance or retreat the dual time zone feature are integrated into the left side of the case.

That familiar Nautilus bump is actually two buttons. The travel hand jumps with each press of the button and can easily be set to the local time in your destination, or simply hidden beneath the main hour hand when you don’t need to track a second time zone.

The baton-style hands are in rose gold with a luminescent coating. This new model combines three highly sought-after complications: a self-winding flyback chronograph, an easy-to-use Travel Time function (dual time-zone), and a date display, coupled with local time.
