Montres Corum Sàrl, commonly referred to as Corum, is a Swiss watchmaker based in La Chaux-de-Fonds, Canton of Neuchâtel. Founded in 1955, it makes high-quality and high-price watches, many of which are limited editions. The benchmark watch series for Corum is its "Admiral's Cup" series. The company is owned by Hong Kong-based Citychamp Watch & Jewellery Group Limited together with Eterna. Both of these Swiss watch companies are managed by a management committee composed by Yeznig Magdhessian, Soon Boon Chong & Maxime Ranzoni. Corum was also the maker of the World Series of Poker watches that accompanied the World Series of Poker bracelet in 2007, and became the maker of the bracelets themselves in 2007. History Corum was founded in La Chaux-de-Fonds, Switzerland by Gaston Ries and his nephew, René Bannwart in 1955. One year later, the first Corum’s watches were being produced. Corum's claim to fame came early on when the company introduced a watch made out of a $20 gold coin, which was an instant best-seller. Corum is also known for its "World Premiers". Each year, it has produced a limited number of limited edition pieces. In January 2000, the arrival of a new owner and President, Severin Wunderman, gave new impetus to Corum. On 25 June 2008, Severin Wunderman died at the age of 69. In January 2010, on the eve of the jubilee year for Corum, its founder René Bannwart, died aged 95. In April 2013, Corum announced that it had been purchased by the China Haidian Holdings Limited group, today called Citychamp Watch & Jewellery Group. Models Admiral's Cup The Admiral's Cup race was first held in 1957 and the Corum Admiral's Cup watch was introduced just three years later in 1960. This first watch was square, water resistant, and had a sailboat engraved on the back. It had little resemblance to the current Corum Admiral's Cup watches with their twelve-sided (Dodecagon) case design and brightly colored nautical pennants decorating the bezels. The men's Corum Admiral's Cup has been available in 35mm, 37mm, 40mm, 41mm, 44mm, and 48mm sizes as well as in versions with a chronograph complication (by ETA, Frederique Piguet) or with just the time and date. Ladies versions of the line were available from 26mm, 31mm and 34mm. Several materials are available as well: rose gold, yellow gold, two tone, stainless steel and a titanium and rubber fusion on the Admiral's Cup
