Parmigiani Fleurier Tonda Annual Calendar
Take a closer look at this timepiece devoted to astronomy.
The true beauty of the Retrograde Annual Calendar lies in the fact that the wearer maintains a point of contact with the watch each year. The date is automatically adjusted based on the number of days in the month — 30 or 31 — but it works on the basis of 29 days for February, whether or not it is a leap year.
The moon phase on the Tonda Annual Calendar is added to the calendar indications. It is known as a "precision moon phase" because it only needs correcting once every 122 years.
The Tonda Annual Calendar is available in two versions: a rose gold case with a white grained dial – a speciality of the manufacture; a white gold case with a black opaline dial.
One of the more recent success stories of the Swiss watchmaking industry, Parmigiani Fleurier emerged from the close relationship between watchmaker Michel Parmigiani and the Sandoz Family Foundation.Find out more >
