Vacheron Constantin Patrimony Ref. 7400 — Ultra-Thin White Gold Elegance
A refined Vacheron Constantin Patrimony dress watch from the early 1970s, defined by its ultra-thin 18k white gold case. The beautifully preserved blue sunburst dial features stick indexes hands, creating a subtle yet striking contrast that embodies mid-century sophistication.
This example stands out for its excellent overall condition and balanced proportions, measuring just 6 mm in thickness, making it an ideal under-the-cuff companion. Inside ticks the legendary Vacheron Constantin Cal. 1120, one of the finest ultra-thin automatic movements ever produced with a 21c gold rotor.
A timeless expression of haute horlogerie, understated, elegant, and unmistakably Vacheron.
