The Vacheron Constantin Ref. 4737, affectionately nicknamed the “Cioccolatone,” stands as one of the most distinctive and admired timepieces ever produced by the Geneva manufacture. Made in 1953, this exceptional wristwatch in 18K yellow gold is characterized by its oversized, square, and gently curved case — a design reflecting the bold and fluid aesthetics of 1950s American automotive design. Powered by the automatic bumper Calibre 477/1, produced for only a short period between 1950 and 1952, the watch is a rare example of technical ingenuity combined with refined artistry. Signed on the case, dial, and movement, it exemplifies Vacheron Constantin’s tradition of elegance, craftsmanship, and originality. Its nickname “Cioccolatone” derives from its case shape, reminiscent of a square of chocolate, perfectly encapsulating its charm and character. The design was so timeless that it inspired later reissues such as the Toledo 1952 and the Historiques Toledo 1951, confirming its enduring influence on the brand’s heritage. With its bold presence and sculptural form, the Ref. 4737 remains a masterpiece of mid-century watchmaking and a symbol of creative sophistication.
