The origins of this timepiece now appearing in a wristwatch version date back to 2011, with the launch of a table clock inspired by a pocket watch displaying an Arabic calendar that was restored in the Manufacture’s workshops. The expertise developed led the brand to develop the Hijri Islamic calendar in wristwatch form, a feat of miniaturisation that won the 2020 Grand Prix d’Horlogerie de Genève (GPHG) Innovation Prize.


In the Islamic world, the calendar is based on lunar cycles. The Islamic or Hijri lunar calendar consists of 12 months of 29 or 30 days – depending on the phase of the moon – and is used to identify Muslim festivals. Known as the Hegira (meaning “flight), the prophet Muhammad’s escape in 622 CE from Mecca to Medina (now in Saudi Arabia) is the starting point for the calculation of Islamic time, representing the moment when the first Muslim community was founded.


Compared to the first version, the TONDA PF Hijri Perpetual Calendar has evolved to reflect the Maison’s new aesthetic codes. The case and knurled bezel are in 950 platinum, the platinum bracelet is seamlessly integrated and the sandblasted platinum dial bears solid gold hour-markers, logo and hands. In terms of content, the movement designed and developed by Parmigiani Fleurier remains identical to that of the model awarded the GPHG prize in 2020. The complete calendar information shows the hours, minutes, date in Arabic numerals, the name and length of the months in Arabic calligraphy, the days of the month and the years. The ninth month is marked in green on the counter at 3 o’clock. It also displays the double moon phase for both Northern and Southern hemispheres.


The Hijri calendar, which is the Islamic calendar, has some connection to nomadic traditions, but its primary basis is religious. The calendar is based on the lunar cycles and was first introduced in 622 CE, when the Prophet Muhammad migrated from Mecca to Medina. This migration, known as the Hijra, marks the beginning of the Islamic era and the start of the Hijri calendar.
However, it is also worth noting that the use of a lunar calendar was common among pre-Islamic Arab tribes, including nomadic ones, who used the moon to track the passage of time and the seasons for practical purposes such as knowing when to move their herds
