Whole civilizations once set their calendars by the moon, long before phones ever did. Built around the rare Islamic Hijri calendar, this Parmigiani Fleurier turns that ancient sky-watching into a sports watch you can wear every day. Collectors who already own the usual grails tend to stop cold the moment they see it.

Presents itself in brand new condition with no signs of wear. Wrapped in deep viridian green, the guilloché dial ripples with barleycorn waves and fine Arabic script. Framed by a fluted bezel in solid 950 platinum, the rim shines like a fresh-minted coin. Set against blue aventurine, the twin moon glitters with real stardust and drifts between northern and southern skies.

Functions include hours, minutes, seconds, Hijri perpetual calendar, date, month, leap year indication, and dual hemisphere moon phase. A knurled crown at 3 o’clock winds the automatic movement when pushed in and sets the time when pulled out. Recessed correctors along the side set the date, month, year, and moon phase with the supplied Parmigiani stylus. After a long rest, wind it first, set the calendar, then set the date to yesterday and walk the hands past midnight to today. Inside, the PF009 holds close to 48 hours of power, and the watch resists water to 100 meters.

Comes as a complete set, double boxed with warranty card and leather card holder.

Rarely does a watch carry an entire culture on its face and still feel this alive on the wrist. One of the few pieces made for the collector who wants meaning, not just metal. Anyone who gets it will know within a heartbeat, and hesitation is how these quietly slip away.
