In 1955 René Bannwart and Simone Ries founded this company in La Chaux-de-Fonds, specializing in extravagant watches with mechanical and quartz movements.

The first workshop of Corum originated in a small factory, headed from 1924 by Gaston Ries (1891-1958), the father of Simone. Bannwart and Simone Ries took the lead and in 1956 brought the first watches designed by René Bannwart on the market.

The model Golden Bridge with a miniature bar movement is one of the most famous watches by Corum. In 1976 the son of René Bannwart, Jean-René Bannwart, became partner and in 1987 director of Corum. 1995 the construction of the architecturally interesting production building in La Chaux-de-Fonds was carried out.

New owners

In 2000 the American Severin Wunderman acquired 90% of the shares, 10% remained with Jean-René Bannwart. Kurt Schaffo refined special movements for Corum.

In April 2013 Corum was taken over by the Chinese holding company China Haidian, now known as Citychamp.
