Vacheron Constantin 2450

Caliber 2450 is an in-house automatic movement launched in 2010 as the successor to the JLC 920-derived 1120. Operating at 28,800 vph, it serves as Vacheron Constantin's modern manufacture caliber for thin dress watches, notably the Patrimony collection. The movement remains in production and continues to serve as a base for selected complications within the brand's dress watch lineup.
