Previously only available in 18K 4N pink gold, the new Vacheron Constantin Historiques Ultra-Fine 1955 makes its appearance in 950 platinum. Testifying to Vacheron Constantin’s ancestral expertise in the making of ultra-thin watches, the new Historiques Ultra-Fine 1955 ref. 33155/000P-B169 stays true to its lineage with an ultra-thin case construction and powered by the same calibre that made its first appearance 61 years ago, during the golden era of watchmaking.
