Parmigiani Fleurier achieves an unparalleled pinnacle in luxury watchmaking with the TONDA PF Hijri Perpetual Calendar, a groundbreaking feat that integrates the third cultural calendar into a singular collection. Its dial reveals a 12-hour counter depicting the 30-year cycle, elegantly distinguishing between "abundant" years of 355 days and "common" years of 354 days. At 3 o'clock, another counter precisely enumerates the months, with a vibrant red highlighting of Ramadan. The duration of the months alternates between 29 and 30 days, indicated by a counter at 9 o'clock, while the phases of the moon, showcased in blue aventurine at 6 o'clock, provide a captivating display of lunar movement across hemispheres. Adorned with touches of gold, the verdant green dial of this watch, housed in a steel case with a platinum bezel, is truly mesmerizing. By uniting the Chinese Xiali, Gregorian, and Hijri calendars in one collection, Parmigiani Fleurier not only underscores its dedication to horological excellence and innovation but also honors the diverse cultures and their unique perceptions of time.
