Corum in watchmaking
Corum was founded in 1955 and quickly established a reputation for unconventional forms and playful displays. The Coin watch placed a movement inside a genuine gold coin, the Admiral developed nautical signal-flag markers, and the Golden Bridge made a long linear movement the architectural center of the watch.
