Patek Philippe Nautilus Perpetual Calendar Ref. 5740/1G-001

Rumours of a Nautilus with a perpetual calendar were rampant just prior to the start of Baselworld 2018. Lo and behold, they were actually true! If you think about it, introducing the perpetual calendar to the Nautilus makes sense. After all, the iconic Patek Philippe sports line has already incorporated the chronograph, the travel time, and even the annual calendar. Moreover, the brand’s fiercest rivals, Audemars Piguet and Vacheron Constantin, have long gotten the perpetual calendar onto their flagship sports watches in the form of the Royal Oak Perpetual Calendar and the Overseas Perpetual Calendar, respectively. A market gap had existed within the Nautilus collection, and filled that gap Patek Philippe has, with the all-new Nautilus Perpetual Calendar Ref. 5740/1G-001.

This launch of the new Ref. 5740/1G-001 is no trivial matter, as it is the first time a ‘grand complication’ is presented in the Nautilus line. Rendered in white gold, the case and bracelet of the Ref. 5740/1G-001 features the typical superb finishing afforded to all Nautiluses (Nautili?). One thing different about the exterior of the new Nautilus though, is that it is equipped with the brand’s new patented fold-over clasp which now features four independent catches to optimise opening and closing and to prevent unintentional release of either of the two clasp segments.

The dial remains Nautilus through and through with its sunburst blue treatment and raised horizontal embossing. The perpetual calendar is displayed analogue-style; its layout is identical to that of the Calatrava Perpetual Calendar Ref. 5327, which is no coincidence given that the two references share the same movement, the Calibre 240 Q (more on the movement later).

The correctors for the perpetual calendar (day correction at 9 o’clock, date correction between 11 and 12 o’clock, month correction at between 12 and 1 o’clock, moon phase correction at 6 o’clock) have been optimally positioned with a system of deflection mechanisms and seamlessly integrated into the Nautilus case design.

Thanks to Patek Philippe’s trusty ultra-thin self-winding Calibre 240, a recessed 22k gold mini-rotor, and a particularly slender calendar module, the merely 8.32 mm-thin case was possible. In fact, the Ref. 5740 is the brand’s thinnest perpetual calendar model – all the more impressive considering that it is also a sports model. The movement, as to be expected, is adorned with the usual superlative finishing that comes with the prestigious Patek Philippe Seal.

The Ref. 5740/1G-001 is set to retail at CHF105,000.
