This is a beautifully preserved Vacheron Constantin Ref. 7397, manufactured in the 1960s. It features an oval design, stainless steel screw-back waterproof case, automatic movement, and date function.
It houses the renowned automatic movement Cal. K1072/1, equipped with a gold rotor, ruby bearings, Gyromax balance, and a quick-set date mechanism (date can be advanced by moving the hands back and forth between 8 PM and midnight).
Among Vacheron Constantin's offerings, this model is one of the few with a practical stainless steel screw-back waterproof case suitable for daily wear. The highly legible silver dial, with bar indexes and baton hands, offers excellent visibility. With top-class practicality among vintage Vacherons and a simple, timeless dial design, this is a model you can enjoy for many years to come.
