Founded in New York City in 1932 by Harry Winston, known as the King of Diamonds, the eponymous brand is known for its incredible diamond and gemstone jewelry, and – as of 1989 – watches. Today, Harry Winston is owned by the Swatch Group and creates high-jeweled and high-horology timepieces. It was known for its incredible Opus series (from 1998-2005) where it worked with independent watchmakers to create a highly innovative series each year. Today, its best collections include The Avenue, Project Z, Histoire de Tourbillon, Emerald, and Ocean.
