Harry Winston opened his jewelry company in New York in 1932 and became one of the best-known diamond dealers of the century. The company began making watches in 1989. In 2001 it started the Opus series, in which a different independent watchmaker designed each model, from François-Paul Journe on Opus 1 to Vianney Halter on Opus 3. Swatch Group bought Harry Winston in 2013.

Inside this watch, two separate mechanisms keep time. On the left, a tourbillon that turns on three axes drives the hours and minutes. On the right, a karussel, another kind of rotating cage, drives a separate display that you can reset to zero. Harry Winston made 20.

Harry Winston built the Opus 14 with independent watchmakers Franck Orny and Johnny Girardin.

Harry Winston made only 50.
