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 and thus especially pricey. The name Corum comes from the Latin word quorum which means the necessary number of people needed to make a society or assembly official. Their logo, the upright key, goes back to their first motto, "The key to perfect time." It still remains relevant with their newest motto, "Unlock and conquer."
Corum's claim to fame came early on when the company introduced a watch made out of a $20 dollar gold piece which was an instant best-seller. Even though this had been done before on pocket watches, Corum was the first and only one ever to do a wristwatch.
The benchmark watch series for Corum is its "Admiral's Cup" series. The Admiral's Cup stands nearly alone in its ability to calculate the tides of the sea. Corum has also been the maker of the World Series of Poker watches that accompanied World Series of Poker bracelet in 2007, and became the maker of the bracelets themselves in 2007.
Their unique Golden Bridge model is yet another example. The watch has four sapphire crystal sides which allow you to see every side of the beautiful and detailed linear movement, which is held only by the golden bridge.
