  • Catalogue Essay

    Introduced in the 1950s, the Vacheron Constantin “Cioccolatone” features an oversized square-shaped curved case reminiscent of a block of chocolate, hence its nickname. Bearing essentially the same case shape and design as the coveted ref. 4737, the ref. 6440 Q features an additional date function that is powered by the firm’s self-winding cal. K1072. Rare timepieces that play its important role in the history of the oldest watch manufacturer, the Cioccolatone is adored by collectors due to its unique appeal and rarity.

    The present example Vacheron Constantin Cioccolatone ref. 6440 Q in yellow gold is paired beautifully with a matching champagne linen-textured dial with unusual rectangular-shaped art deco-style indexes.

  • Artist Biography

    Vacheron Constantin

    Swiss • 1755

    The world's oldest watch brand in continuous operation since its founding in 1755, Vacheron Constantin was the first watch company to manufacture movements with interchangeable parts beginning in 1839. Vacheron's watches are admired for their Latin-influenced case designs, well-balanced proportions and exquisitely finished movements of the highest quality. The Geneva-based manufacturer is known for their highly complicated masterpieces, including the King Farouk Grand Complication made in 1935, the Tour de l'Ile that was the most complicated serially produced wristwatch when introduced in 2005 and the 57260 — the world’s most complicated watch — made in 2015.

    Key vintage models include minute repeating wristwatches such as the references 4261, chronographs such as the references 4178 and 6087 and the oversized Cioccolotone models such as ref. 4737. Collectors also appreciate Vacheron's Chronometer Royal pocket and wristwatches, as well as the '222,' the brand's first luxury sports watch produced from 1977 through 1984.
