A new version in steel with a sunburst blue dial featuring a black-gradient rim

2006, the year of the 30th anniversary of the Nautilus collection, saw the introduction of Reference 5980/1, Nautilus flyback chronograph. This model was joined in 2014 by Reference 5990/1, Nautilus Travel Time Chronograph, initially offered in a steel version (5990/1A-001), complemented in 2021 by a rose gold version (5990/1R-001).

As the successor to the 5990/1A-001, Patek Philippe has revisited the steel version by combining it with a new blue dial featuring a radiant sunburst pattern and a black-gradient rim. A perfect example of legibility, this dial is enhanced by the horizontally embossed motif typical of Nautilus watches and is adorned with applied hour markers and white gold rounded baton-style hands, all with luminescent coating.

The case water-resistant to 120m, octagonal bezel, chronograph pushers (at 2 and 4 o’clock), local time pushers (at 9 o’clock) and steel bracelet are enhanced by elegantly alternating polished and satin finishes.

Self-winding CH 28-520 C FUS caliber combines three useful and practical complications: a flyback chronograph, a Travel Time function (dual time zone with two central hour hands, one of which is skeletonized for home time) and a date indicated by hand (at 12 o’clock) coupled with the local time. Its original construction combines tradition (column-wheel drive) and the avant-garde (vertical disk clutch). The flyback function enables instant restarting of timing operation without first having to stop the hands. The central chronograph hand can also be used as a running seconds display.

The steel bracelet with patented Patek Philippe fold-over clasp, secured by four independent catches, is equipped with a new lockable adjustment system that makes it possible to gain 2 or 4 mm in length thanks to simple, quick and secure handling, thus ensuring greater comfort in everyday life.

The new Reference 5990/1A-011 replaces Reference 5990/1A-001 and joins the existing Reference 5990/1R-001 in the collection.
