Corum was founded in 1955 in La Chaux-de-Fonds, Switzerland, by Gaston Ries and his nephew, René Bannwart.

Soon after its establishment,Corum introduced a watch made out of a $20 gold coin, which was an instant best-seller.

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 face.

Created by the owner of the brand at the time, Severin Wunderman,[1] the Bubble had an unusual huge sapphire glass face.

The XXL had limited edition versions including Lucifer, Baron Samedi, Bats, Joker and Royal Flush.

It sports a sapphire case back engraved with a laurel crown in honor of Romulus, the founder of ancient Rome.

Corum has produced coin watches for over fifty years, with automatic, manual wind or quartz movements.

The Corum Artisan watch line is defined by dials depicting wild animals, exotic locales, or historic scenes.
