Perpetual works in progress

SINGAPORE (June 18): A stable of thoroughbreds necessitates judicious breeding, and Patek Philippe has always exercised conscientiousness in the pairing of classics and complications. Conditions must have been favourable, then, for the maison to update not one but two cult collections with new functions.

The debut of the Nautilus collection in 1976 showed clear affinity with its namesake. References to Captain Nemo’s vessel in Twenty Thousand Leagues Under the Sea, the likes of the octagonal case shaped like a porthole, transferred the drama spun by Jules Verne onto wrists, as did the seamless integration of bracelet into case and the horizontally grooved dial recalling the strong, linear advance of waves. Prior models had seen chronographs and annual calendars worked onto their faces but Patek has now deemed the collection mature enough to take on its first grand complication. Equipping the Patek Philippe Nautilus Perpetual Calendar 5740 with its eponymous complication is the self-winding calibre 240, a famously ultra-thin movement with a recessed 22-carat gold mini-rotor and slender calendar module. This is the slimmest perpetual calendar movement manufactured by the watchmaker and its shy proportions translate into a 40mm white gold case just 8.42mm thick. The display on the dial — brass and coated in blue PVD with a subtle sunburst finishing — is a harmonious symphony of analogue indicators. The sub-counter at three o’clock informs the month and leap-year cycle while day of the week and 24-hour time are told in a mirroring counter at nine o’clock. A slightly larger subsidiary dial at six o’clock exhibits the date and an extremely precise moon phase in an aperture within, deviating from the exact position of the moon by merely a day every 122 years. Correctors for day, date, month and moon phase functions are neatly integrated into the face, optimising performance without interfering with the aesthetic, thanks to an ingenious system of deflection mechanisms.
