Rare Vacheron Constantin Pink Gold Ref. 4657

This is an incredible and rare Vacheron Constantin 18kt pink gold reference 4657, circa the 1950's.   Embodying the bold, geometric optimism of mid-century design, this vintage Vacheron Constantin Reference 4657 is a rare masterpiece for the discerning collector. Sharing the same striking design DNA as the legendary, oversized "Cioccolatone," this reference offers an exquisite blend of architectural form and mechanical innovation from one of the world's oldest and most prestigious watchmakers.  The solid 18kt pink gold square case features a stepped profile with flared accents and pronounced fluted lugs. This sculptural design creates an exceptional presence on the wrist, reflecting light beautifully from every angle.  The  original dial is a masterclass in vintage execution, featuring a sophisticated two-tone guilloché sector layout. A rich, ribbed-pattern border provides the perfect backdrop for applied gold pyramid dart indices and stylized Arabic numerals at the quarters.  Powering this beauty is Vacheron Constantin's historic Caliber 12'''-477/1 "bumper" automatic movement—a pioneering piece of engineering that delivers a distinct, tactile feel as the weighted rotor bounces between spring bumpers to wind the watch.  The condition of this watch is exceptional.  Being that this watch is in pink gold with its incredible original guilloche dial makes this watch a rare piece of horological history.
