Patek Philippe Ref. 5740/1G-001 Nautilus With A Perpetual Calendar
With the first perpetual calendar in the Nautilus collection, Patek Philippe introduce new patented fold-over clasps that stand out with improved safety features.
Patek Philippe presents the first grand complication in the Nautilus line, showcasing an analog perpetual calendar, one of the manufacture’s most coveted classics since 1985. It is a unique combination of casual sportiness and technical finesse, robustness and high-end watchmaking artistry, endowed with the discreet elegance of an 18K white-gold case and the utility of a calendar that automatically recognizes the number of days in each month, including the periodically recurring 29th of February.
Thanks to the famous ultra-thin self-winding caliber 240 movement, a recessed 22K gold minirotor and a particularly slender calendar module, the 8.32 mm high case – it is water resistant to 60 meters – is remarkably svelte. In fact, it is Patek Philippe’s thinnest perpetual calendar. The architecture of the movement and its refined finissage, including the bridges with chamfered and polished edges as well as the Calatrava cross engraving on the winding rotor, can be admired through the sapphire-crystal display back.
The characteristic design of the bezel is emphasized by vertically satin finished surfaces that contrast against polished chamfers. The dial is decorated with raised horizontal embossing, a typical facet of men’s Nautilus watches, and features the same sunburst blue that graced the versions released on the occasion of the 40th anniversary of the Nautilus in 2016. The porthole-inspired case design gave this model its name. Legibility in daylight and in the dark is optimized with broad hour and minute hands as well as the applied white-gold hour markers with luminescent coatings.
The three subsidiary dials of the perpetual calendar with analog displays (day of the week and 24-hour dial at 9 o'clock, month and leap- year cycle at 3 o'clock, date and moon phases at 6 o'clock) are harmoniously integrated in the subtly rounded octagon of the dial. A refined detail: the subdial for the date, the most important calendar indication, is slightly larger than the two others. The 24-hour display simplifies calendar settings. The moon-phase display is extremely precise. It is controlled by a mechanism that deviates from the actual position of the moon by merely one day every 122 years.
The correctors of the perpetual calendar (day correction at 9 o'clock, date correction between 11 and 12 o'clock, month correction between 12 and 1 o’clock, moon-phase correction at 6 o'clock) were optimally positioned with an ingenious system of deflection mechanisms and seamlessly integrated in the Nautilus case design.
The white-gold bracelet, also integrated in the case, echoes the finissage of the case and bezel, alternating polished central links with satin-finished lateral links. To improve wearing comfort, Patek Philippe has introduced a totally new, patented fold-over clasp. It features four independent catches to optimize opening and closing and to prevent the unintended release of either of the two clasp segments.
