Automatic & retrograde annual calendar movement

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.
