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.
