Launched during the WATCH ARTTM grand exhibition in Tokyo 2023, in a 300-piece limited series, the new Patek Philippe World Time Reference 5330G-010 features a patented world first: a date indication synchronized with local time, meaning that of the selected time zone appearing at 12 o’clock and displayed by the central hands.
To provide this useful and highly practical function, Patek Philippe has developed a new movement, the 240 HU C caliber, based on the ultra-thin selfwinding 240 HU caliber and equipped with an innovative patented differential system for managing the local-time date. This date mechanism alone comprises 70 parts.
The date is displayed on the beveled flange by a red-tipped central hand – the first ever from Patek Philippe made of glass and for which two patents have been filed.
The name of Tokyo appears in red on the city disk corresponding to the 24 time zones. On the 24-hour disk – subdivided into two day/night zones identified by their rhodium-plated or plum-colored background – the sun symbol is replaced by a red rising sun, the emblem of Japan. A red dot between Auckland and Midway marks the date line.
The local time of the selected time zone at 12 o’clock is indicated by a skeletonized hours hand inspired by the “Southern Cross” constellation, while the minutes hand features a lozenge-shaped cutout. Thanks to an ingenious mechanism patented in 1999, the user can simultaneously correct all the World Time displays – now including the date – in one-hour increments by simply pressing the pusher at 10 o’clock.
The plum-colored dial is adorned with a hand-guilloched center and the entirely polished white gold case measuring 40 mm in diameter is distinguished by its curved two-tier lugs.
The Patek Philippe World Time Reference 5330G-010 is fitted on a shiny black alligator leather strap with plum-colored hand stitching and a white gold fold-over clasp. The sapphire case back is adorned with the “Patek Philippe Tokyo” transfer.
