The Vacheron Constantin ref. 4906 was all about functionality in the 1950s, offering an automatic caliber and a screw-down waterproof caseback. Its case measures a substantial 35,5 mm across, while a vast number of dial and hand combinations exist, true to Vacheron Constantin's form in that era.
Not only is this example in outstanding condition, but just look at those dial and case details! We assume that this piece is a 1/1 worldwide and was a custom made piece by Vacheron Constantin for a special customer.
