The Traditional Chinese Calendar watch by Blancpain is based on fundamental principles established for millennia and profoundly rooted in Chinese tradition. On its fascinating dial, the hours, minutes and the Gregorian calendar rub shoulders with the main indications of the Chinese calendar: traditional double-hour indication, day, month with indication of leap months, signs of the zodiac, as well as the five elements and the 10 celestial stems. The moon phases, a key element in Blancpain complete calendars, are also presented and play a particularly important role in this model, given the link between the lunar cycle and traditional Chinese months.

Contrary to the Gregorian solar calendar which uses the solar day as the base unit, the traditional Chinese calendar is a lunisolar calendar, meaning a solar calendar with the lunar cycle (29.53059 days) as its base unit. The counter at 12 o'clock indicates the double-hour numerals and symbols (24-hour cycle); while the one at 3 o'clock shows the elements and the celestial stems (10-year cycle). The month of the Chinese calendar (12-month cycle), its date (30-day cycle) and the leap month indicator appear at 9 o'clock, while the 12 o'clock aperture reveals the zodiac sign of the year in progress (12-year cycle); and the moon phases are displayed at 6 o'clock. The hours, minutes and the Gregorian calendar are presented in the centre. 2018 is the year of the dog in Chinese lunar years. Hence, a dog is standing at the 12 o'clock aperture to indicate a soaring new year.

The self-winding Calibre 3638 powering this watch is endowed with a 7-day power reserve. The 45 mm-diameter platinum case is fitted with a crown adorned with a cabochon-cut ruby and comprises five integrated under-lug correctors serving to adjust the indications. It features the classic signature attributes of the Villeret collection: its double-stepped shape; a grand feu enamel dial with a chapter ring composed of gold appliques, and indications transferred before the firing process, the main hands shaped like slightly hollowed leaves; and the blued steel Gregorian date pointer appearing in the traditional serpentine form. This 50-piece limited-edition watch is equipped with a white gold oscillating weight, engraved with a dog. This new model is also available in a non-limited red gold version.
