The 'Cioccolatone', one of the brand's most recognizable and captivating wristwatches, was born out of this creative momentum. Its large, softly rounded allure was first introduced in 1957 and is lovingly referred to by Italian collectors for looking like a square of chocolate. It is characterized by its elegant three-stepped bezel and voluptuous proportions. The present example, powered by the automatic caliber 1072, embodies the post-war modernism and refined charm that characterized Vacheron Constantin's mid-century designs. Its case has developed a lovely patina over the years, turning a warm, nearly bronze color that adds to its vintage appeal. Reference 6440 was made in a number of variations, most of which were in yellow gold, and had either manual or automatic movements. The reference's adaptability and enduring appeal among collectors were highlighted by the fact that some examples had time-only dials, while others had complete calendars and moon phases.
