Nautilus Travel Time Chronograph Steel 5990/1A-001

Two Zones and a Chronograph.

A black graduated 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 an hour at a time while the movement keeps running.
