Crafting The Complication: Calibre GP9530

The new in-house Calibre GP9530 is a fine example of our artisans' expertise in complex skeletonised calibres. This 475-part openworked calibre combines a minute repeater, a tourbillon and a new self-winding system. Its assembly and decoration require nearly 440 hours of work - with 1,340 hand-polished chamfers - of which 295 are interior angles, bearing witness to the level of craftsmanship behind this grand complication.
