Baselworld 2018 once again set the stage for a horology premiere, as Patek Philippe unveiled their first “Nautilus” equipped with a perpetual calendar. Making this occasion evermore remarkable by managing to fit all these complications in their thinnest sized “Nautilus” yet.

The “Nautilus” model is an iconic timepiece that manages to eloquently combine a certain sports appeal, with technical sophistication, all inside a truly unique, futuristic and timeless watch design. It easily represents watchmaking artistry crafted in a white-gold case featuring the utility of a calendar that automatically recognizes the number of days in each month, as well as the periodically recurring 29th of February.

As aforementioned this is the first time a “Nautilus” model has been equipped with a perpetual calendar. Initially the first grand complication added to this Patek Philippe was a chronograph function, followed by version with a second time zone (Travel Time) and the “annual calendar”.

The 40mm case is made of 18k white gold with a combination of brushed and polished finishes. It’s been constructed with a transparent exhibition case back that allows to view the inner workings of the mechanical movement.

At a mere 8.32mm of thickness this is the thinnest Patek perpetual calendar ever manufactured. Topped by a sapphire crystal and equipped with a screw-down crown that assures water-resistance on this watch can reach up to 60 meters (196 feet).

Time is exhibited on a blue sunburst dial with the classic horizontal ribbing, commonly found on the “Nautilus” model. Reading time is done via white gold applied hour index markers, followed by a ring of small printed white dots as minute index markers. The central hands and hour index markers have been given a luminescent coating, for an enhanced legibility.

What we see here is the prominent QP (quantième perpétuel) layout that in this case displays the: month, day, date, leap year, Moonphase and a 24-hour cycle. All these indicators split-out on three sub-dials with doubling functions: a month dial with leap years in its midst at the 3 o’clock position; a date dial with a Moonphase in its midst at the 6 o’clock position; and a day of the week dial with a 24-hour indication in its midst at the 9 o’clock position.
