Often named “Cioccolatone” for its resemblance to a chocolate square, this Vacheron Constantin reference 4737 is a striking example of mid-20th-century design, reflecting the bold, curved aesthetics of the 1950s. The watch features a distinctive large, organic square case with rounded, stepped lugs and a subtly curved bezel, capturing the era’s fascination with clean lines and biomorphic forms. The 4737 is particularly notable for its exceptional preservation, maintaining its original crispness and charm since its release. This model is part of a collection that includes both manual and automatic movements, with variations such as subsidiary seconds, central seconds, date apertures, and even rare triple calendar with moon phases. The present automatic example, with central seconds and no date, is prized for its elegant simplicity and the purity of its design. This piece exemplifies Vacheron Constantin’s mid-century artistic flair and avant-garde approach, making it a noteworthy addition to any collection. It is accompanied by its original warranty, receipt, and box, further enhancing its value and appeal.
