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.
