The calibre PF331 is the first self-winding mechanical movement from Parmigiani Fleurier. The movement has a modular design which allows for a diverse range of Kalparisma versions. It can be equipped with small seconds at 6 o'clock or large central seconds, while maintaining the delicate balance of the dial. This movement offers the finest Haute Horlogerie finishes you would expect from Parmigiani Fleurier, and ones which very few brands would apply to such a mechanism. The bridges are sandblasted, drawn out or "Côtes de Genève" decorated, then bevelled by hand and, finally, rhodium-plated.
Finish and material of the rotor can differ depending on the watch.
