Parmigiani Tonda Annual Calendar

Parmigiani Fleurier presents the Tonda Annual Calendar, a piece that conveys Michel Parmigiani’s passion for these complications. In his honour, the manufacturer has developed the calibre PF339, which features both a retrograde annual calendar and a precision moon phase. In combination, these two complications ensure the new Tonda Annual Calendar is a piece wholly devoted to astronomy, as it transcribes the rotation of the Earth in relation to both the sun and the moon.

Using the PF331 automatic movement as a base, Parmigiani Fleurier developed the calibre PF339, equipped with an additional module dedicated to the Retrograde Annual Calendar and its precision moon phase. The unique feature of this automatic movement, with a power reserve of 50 hours, is its series-mounted double barrel. This stabilises the distribution of energy so that it is transmitted to the regulator at a constant level. The bridges are hand-bevelled and decorated with Côtes de Genève, displaying exemplary craftsmanship down to the smallest details – even those that remain hidden.
