Rather than waiting for the doors to officially open at Baselworld 2019, Patek Philippe has just announced 15 new watch models on the eve of the event. While there’s plenty to unpack there, we wanted to immediately get a closer look at the fresh Nautilus models. Here are the new Patek Philippe Nautilus watches for men and women from Baselworld 2019.

A New Dial for the Men’s Nautilus Annual Calendar Ref. 5726

Patek Philippe unveiled the very first ref. 5726 Nautilus back in 2010, and this year, a new dial joins the collection. The new Patek Philippe Nautilus Annual Calendar with Moonphase ref. 5726/1A-014 features a subtly graduated dial from mostly blue to black on the periphery – similar to the inaugural 1976 Nautilus – complete with the obligatory horizontal embossing. Prior to this release, the Nautilus Annual Calendar only came with a black dial or a white dial.

The rest of the watch retains the familiar Nautilus design from the steel porthole inspired 40.5mm case to the integrated steel bezel. As an annual calendar version, the Nautilus ref. 5726/1A-014 includes a pair of windows at the top to display the day and month, along with the date aperture at 6 o’clock. The moonphase sub-dial at 6 o’clock is framed by a 24-hour indicator.

The sapphire caseback gives us a view of the Caliber 324 S QA LU 24H/303 inside the watch, which offers a minimum power reserve of 35 hours. Of course, as the name of the complication suggests, the annual calendar only requires one manual readjustment per year – when February turns into March.

A New Size and Dial Colors for the Ladies’ Nautilus Models

For the ladies, Patek Philippe is offering up five new automatic Nautilus models, some with slightly larger cases and new dial color options.

The automatic steel and diamond bezel ladies’ Nautilus watches now sport slightly larger 35.2mm cases (compared to previous 33.6mm), which is now the same size as the other self-winding women’s Nautilus models. There are three dials to choose from: blue opaline (ref. 7118-1200A-001), silvery opaline (ref. 7118-1200A-010), and gray opaline (ref. 7118-1200A-011). Also new to the watch is the clasp extension system on the steel bracelet, which provides the wearer between 2mm and 4mm of extra length.

Previously, all rose gold versions of the automatic ladies’ Nautilus watches came with 35.2mm cases and diamond-set bezels. For 2019, Patek retains the same case size, but now offers two new models with smooth gold (sans diamonds) bezels. The two dial colorway options include silvery opaline (ref. 7118/1R-001) and golden opaline (ref. 7118/1R010). The new rose gold Nautilus watches also come fitted with the new fold-over clasp with an integrated adjustment system

Similar to previous self-winding ladies’ Nautilus watches, the five new models run on the automatic Caliber 324 S C with a 35-hour power reserve, which can be seen via the exhibition caseback.
