The calibre PF331 is the first self-winding mechanical movement from Parmigiani Fleurier. It 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 sand-blasted, drawn out or "Côtes de Genève" decorated, then bevelled by hand and, finally, rhodium-plated. The oscillating weight is adorned with a guilloché barley grain motif. Michel Parmigiani has high expectations when it comes to the brand's craftsmanship: each component, however small or hidden, deserves the very finest finishes. This attention to detail is what makes the Kalparisma Agenda Galaxy so precious.
