Vacheron Constantin 1790

The Vacheron Constantin Calibre 1790 is an ultra-thin manual-wind skeleton movement introduced in 2022 and remains in production. It belongs to the 17xx caliber family and represents an in-house development, reflecting the brand's commitment to manufacturing proprietary mechanisms. The skeletonized construction exposes the finishing on the movement's bridges and mainplate, a hallmark of haute horlogerie presentation. This caliber continues the lineage of VC's ultra-thin manual movements.
