The "Challenger Deep", at a depth of 10,916 m, is the deepest known point under the ocean's surface. On 23 January 1960, Swiss explorer, Jacques Piccard and U.S. Navy Lieutenant Don Walsh, at the controls of the "Trieste" bathyscaphe, were the first to reach Challenger Deep. To commemorate this spectacular achievement, Emile Chouriet presents its sports watch, the "Challenger Deep". Steel or ceramic, the rotating bezel is available in a black or blue version. Its ceramic coating gives it a precious stone appearance. The use of luminescent material on the dial produces green readability in a dark environment. It is water resistant to 300 meters.
