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. 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. The 22-carat gold oscillating weight features a guilloché barley grain motif. Michel Parmigiani has high expectations when it comes the brand's craftsmanship: each component, however small or hidden, deserves the very finest finishes. This attention to detail is what makes the Kalparisma Nova Collection so precious.
