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 Jérôme Biard, who was appointed on 1 September 2017.
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.
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 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.
