CULTURAL ODES TO GREAT CIVILISATIONS
We view calendars not only as instruments of measurement but as true mirrors of the civilizations that conceived them. This recognition of calendars as expressions of cultural diversity guides our design process, encouraging us to integrate the specificities of each society into our timepieces.
Our TONDA PF collection showcases three masterpieces dedicated to this theme: The Islamic Hijri calendar,
the complete Chinese calendar Xiali and the Gregorian calendar.
