Vacheron Constantin 1400

Caliber 1400 is Vacheron Constantin's in-house automatic base movement, introduced in 2004 and still in production. It operates at 28,800 vph and serves as the foundation for the brand's complication calibers within the 14xx family. The movement is manufactured entirely in-house at the company's Geneva facilities. It forms the basis for several Vacheron Constantin complications, including calendar and chronograph variations.
