A ref. 47100 Chronograph Skeleton, a dramatically finished 2310 ébauche chronograph from 1994. Across platinum and yellow gold, fewer than 100 examples were ever made with a far lesser percentage in this platinum. It features a 38mm rounded case with soldered lugs and geometrically fractal shapes in its dial openwork. This was the ultimate showcase of Vacheron Constantin’s technical chronograph ability starting 1991, a balance of mid-century shapes and modern proportions with one of the world’s greatest chronograph calibres as its base.
