In 2011, Michel Parmigiani created the Hijri Calendar Table Clock after he was inspired by the restoration of a pocket watch that featured an Arabic calendar. He, later, miniaturised this in wristwatch form as the Hijri Perpetual Calendar that won the 2020 GPHG Innovation Prize. In 2023, Parmigiani Fleurier released the Tonda PF Hijri Perpetual Calendar in a platinum case with a simpler dial. Now Parmigiani Fleurier introduces a new Tonda PF Hijri Perpetual Calendar in a stainless steel case with a vivid Viridian green dial
The new Tonda PF Hijri Perpetual Calendar has a 100m water-resistant stainless-steel case with alternating satin and polished finishes. Its signature fluted bezel is in 950 platinum, and it is paired with a matching stainless-steel bracelet with folding clasp. The viridian green dial is hand finished with a Grain d’Orge guilloche. The applied hour markers and skeletonised delta hour and minute hands are crafted in 18k gold with rhodium plating. The second hand and calendar subdial hands are made of rhodium-plated steel.
The Tonda PF Hijri Perpetual Calendar is equipped with the Caliber PF009 automatic movement, which operates at 28,800 vibrations per hour (4 Hz) and has a power reserve of 48 hours. The intricate movement has bevelled bridges. The skeletonised rotor is chiselled from platinum with a polished and sandblasted finish. Like the case and dial, it is meticulously finished with Côtes de Genève and perlage throughout.
The Tonda PF Hijri Perpetual Calendar displays all the information on the dial. The 12-hour subdial shows the 30- year cycle with the abundant 355-day years in beige and the standard 354-day years in white. The 3 o’clock subdial indicates the numbered months of the year with the ninth month of Ramadan highlighted in bright red. The 9 o’clock subdial shows the days of the month with an aperture indicating whether it is a 30-day abundant month or a 29-day common month. A white aperture indicates a 29-day month. The activated beige aperture indicates a 30-day month, with the number 30 in beige and written as ۳۰. Finally, the 6 o’clock subdial features the blue aventurine moon phase display, which shows the position of the moon in the northern and southern hemispheres.
