Nautilus Travel Time Chronograph Blue Dial 5990/1A-011

Two Zones and a Chronograph.

A blue gradient dial carrying dual time indication with day and night apertures, plus a flyback chronograph, in steel on the integrated bracelet. Two pushers on the left move local time forward and back an hour at a time while the watch keeps running.

The most complicated Nautilus made in steel, and it still reads at a glance.
