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