Vacheron Constantin 1071

Caliber 1071 is an automatic movement manufactured by Vacheron Constantin. Introduced in 1959, it belongs to the 107X family, which represents the manufacturer's post-1955 automatic caliber series. The movement is not of in-house manufacture, a common practice for Vacheron Constantin during this period when many movements were sourced externally. Production has been discontinued. Notable watches powered by this caliber include references within the classic Vacheron Constantin collection from the 1960s.
