Vacheron Constantin’s reference 4737 is a wonderful example of the artistically flamboyant design language expressed by the brand during the mid-20th century. Focusing on clean lines and biomorphic shapes, the brand created a new aesthetic with this large, organic, square-shaped wristwatch with rounded stepped lugs and bezel, along with the slightly curved case. Introduced in the 1950s, the watch became known by Italian collectors as the “Cioccolatone” for the square-shaped chocolates they enjoy and has, over the last 70 years, become an iconic Vacheron Constantin. Its avant-garde, industrial design exemplifies the beauty and artistic creativity the brand is known for.

In 2003, Vacheron Constantin revived this case shape by launching a full calendar with a moonphase model under the name Toledo 1952. In 2013 the brand re-introduced a model similar in all aspects to the present lot under the name Historiques Toledo 1951.

The present example is distinguished by a very well-preserved case, which allows the beholder to fully enjoy the voluptuously sculpted shapes of the model. This particular configuration, with center seconds and no date, is appreciated by traditionalists and non-conformists for its elegant simplicity and the purity of its design. The golden age of wristwatches is defined by many iconic timepieces, and the “Cioccolatone” is an unconventional watch showcasing the creative exuberance of Vacheron Constantin.
