Nautilus Chronograph 5980/1A-001

The Porthole, Timed.

A black-blue gradient dial with the embossed horizontal relief the case has carried since 1976, fitted with a flyback chronograph and a 60 minute monocounter at 6 o'clock. Steel throughout, integrated bracelet, and a bezel shaped from the porthole of a ship.

The single counter is the reason the dial stays clean at this complication level.
