In the years following the Second World War, watch design underwent a quiet revolution. The prevailing mood favored clarity over ornament, comfort over rigidity, and forms inspired by the organic language of mid-century industrial design. Vacheron Constantin answered with a creation both bold and unmistakable: a generously proportioned, softly squared wristwatch with rounded, stepped lugs and a subtly curved case. Collectors would later christen it the “Cioccolatone”, a nickname as affectionate as it is accurate, an object that perfectly captured the optimism and creativity of the 1950s. Production was always limited, predominantly in yellow gold, with far fewer examples in pink gold and only two pieces known in white gold. Oversized, sensual, and remarkably modern for its time, the design proved so enduring that Vacheron Constantin revived it decades later with the Toledo 1952. The present reference 4764 represents the pinnacle of the Cioccolatone lineage, combining the triple calendar and moon phase with the manufacture’s largest and most expressive case of the era. Within the universe of Vacheron Constantin complications, it also holds a particularly remarkable distinction: it is widely regarded as the rarest calendar wristwatch ever produced by the maison. Even more extraordinary is the state of preservation of the dial. Watches of this type are notoriously difficult to encounter with dials that remain luminous and overall clean over the time; the present example displays a clarity and freshness that is seldom seen, further elevating its desirability among connoisseurs.
Preserved in exceptional condition, sculptural in presence and profoundly charismatic, this reference 4764 stands among the most important Vacheron Constantin wristwatches of the golden age—a true trophy watch destined for the most discerning collections.
