Parmigiani Fleurier PF701

The PF701 is an automatic movement manufactured by Parmigiani Fleurier, based on the Vaucher VMF 5401 caliber. At just 2.6 mm thick, it features an off-centred micro-rotor integrated directly into the main plate, allowing the movement to maintain slim proportions while accommodating additional complications such as calendar or moon phase displays. The rotor winds a mainspring providing 42 hours of power reserve. This movement powers the Tonda 1950 family, including both standard and Sertie variations in rose gold and white gold.
