The world of horological complications is virtually infinite. One of them is truly universal, rooted in every culture and mirroring civilisations: the calendar function. Parmigiani Fleurier presents the TONDA PF Hijri Perpetual Calendar or Islamic calendar.
The highly complex Chinese calendar is a combination of a solar and a lunar calendar, calculated separately and then synchronised. How is this done? By adding an extra lunar month also called a leap or intercalary month. This 13th month is added approximately every three years to bring the two cycles back in sync. Finally, the Chinese calendar divides the solar year into 24 terms, or breaths, which symbolise the agricultural calendar.

Complete Chinese calendar and precision moon phase
The TONDA Gregorian Calendar tells the story of Michel Parmigiani's passion for dates, honoured by Calibre PF339 specially developed by the Manufacture and housing a retrograde Gregorian calendar and a precision moon phase. Together, these two complications compose the TONDA Gregorian Calendar: a timepiece resolutely geared towards astronomy and reproducing the Earth's revolutions around the Sun as well as in relation to the Moon.
