A traditional perpetual calendar’s gears are programmed, when continuously running, to account for the leap month once every four years and different length months in the Gregorian calendar. The Islamic Calendar is based on the lunar calendar with the Hijri Year being made up of 12 months of 29 or 30 days – depending on the moon phase. The lunar calendar uses the phases of the moon to measure time, usually measuring the time from new moon to new moon as one month.

The Fleurier-based watchmaker was the first to introduce the concept of the Hirji Islamic Perpetual Calendar in 2019. The seeds of its development were sown in 1993 when Michel Parmigiani, the founder of the eponymous brand restored an oval-shaped pocketwatch with an Islamic calendar indicating the hour, day, date and month in Arabic calligraphy, and the phases of the moon. This pocketwatch served as the inspiration for a table clock featuring a Hijri Calendar in 2011, the world’s first such calendar.
