Situated at the southern end of the Mariana Trench, 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 achievement, Emile Chouriet presents its first diving watch, the "Challenger Deep".

This timepiece combines function and aesthetics. Its reliability and accuracy are guaranteed to a depth of 300 metres.
The 42mm stainless steel case is equipped with a rotating bezel, available in steel or ceramic, and 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.

The functions of hours, minutes, seconds and date are powered by an automatic movement.
