Harry Winston, Inc. is an American luxury jeweler and producer of Swiss timepieces.[2][3] Founded in 1932 as Harry H. Winston Jewels, Inc. and renamed Harry Winston, Inc. in January 1936,[4][5] the company is named after its founder, Harry Winston, known as the "King of Diamonds".[2][6]
Widely regarded as one of the most prestigious jewelry houses in the world,[7] the company is headquartered in New York City and has been a wholly owned subsidiary of the Swiss Swatch Group since January 2013, when Swatch acquired it from the Toronto-based Harry Winston Diamond Corporation.[3][5][8]

American jeweler Harry Winston, who had traded diamonds through his Premier Diamond Company since 1920, opened his first store as Harry H. Winston Jewels, Inc. in 1932, and the company took its current name in 1936.[3][4] The firm built its reputation acquiring, cutting, and resetting some of the most famous diamonds in the world, including the 726-carat rough Jonker Diamond, purchased in 1935 and cut into twelve stones.[9]
In 1943, Winston became the first jeweler to loan diamonds to an actress for the Academy Awards, dressing Best Actress winner Jennifer Jones; the red-carpet tradition it began made the house a fixture among Hollywood celebrities.[10]
In 1949, Winston purchased the jewelry collection of heiress Evalyn Walsh McLean, including the Hope Diamond, and toured it and other gems across the United States for several years in a charitable exhibition called the "Court of Jewels".[9] He donated the Hope Diamond to the Smithsonian Institution in 1958, famously shipping it by registered mail; the gift helped establish the Smithsonian's National Gem Collection.[11][12] The company opened salons in Geneva in 1955 and Paris in 1957, and in 1960 moved its headquarters to 718 Fifth Avenue, where it remains.[9][13] In 1966, the firm cut the 241-carat rough that became the 69.42-carat Taylor–Burton Diamond, later purchased by Richard Burton for Elizabeth Taylor.[13]
After Harry Winston died in 1978, control of the company passed to his sons, Ronald and Bruce, who entered a decade-long legal battle over the business.[14] In 2000, Ronald Winston and new business partner Fenway Partners bought out Bruce's share for $54.1 million.[15]
The company entered watchmaking in 1989 and established the Harry Winston Rare Timepieces production facility in Geneva, later known for its Opus series of collaborations with independent watchmakers.[3] In 2004, the Toronto-based diamond mining company Aber Diamond Corporation acquired a stake in Harry Winston, completing its purchase of the firm in 2006 and renaming itself Harry Winston Diamond Corporation.[9] In 2010–2011, the company recorded €246 million in total sales, of which €36 million came from watches.[16] In late 2009, the company named Frédéric de Narp, formerly of Cartier North America, as CEO, succeeding Tom O'Neill.[17]
