This exquisite display of the 44.5mm Parmigiani Fleurier Tonda Hegirien Hijri Perpetual Calendar showcases hours, minutes, and the date in Arabic numerals as well as the name and length of each month in stylish calligraphy. It also features a moon phase window that depicts the lunar cycle against a sky of Aventurine microcrystalline quartz. Like all versions of the Tonda Hegirien, this window is comprised of parts that have been hand-decorated in-house by Parmigiani’s craftsmen.
The vision behind this watch was inspired by the lunar-based Hijri calendar. Unlike the sun-based system of the Gregorian calendar, the calendar of the Muslim world tracks time using the cycles of the moon. As such, the months of the Hijri calendar consist of either 29 to 30 days, precisely coinciding with shifting moon phases. Now you can easily track Islamic holidays by being able to keep pace with both the solar and lunar calendars on the Parmigiani Fleurier Tonda Hegirien Hijri Perpetual Calendar.
