Geneva (Revista E) - Fifty years ago, Rolex and the bathyscaphe Trieste made history when US Navy Lieutenant Don Walsh, accompanied by Swiss oceanographer Jacques Piccard, piloted the US Navy vessel to the bottom of the Challenger Deep in the heart of the Mariana Trench, some 200 miles off the island of Guam in the Pacific Ocean. Strapped to the outside of the Swiss-designed submersible was a Rolex watch. A third-generation Rolex prototype of the Deep Sea Special was specifically engineered to withstand the tremendous pressure that would be encountered, approximately eight tons per square inch, at a depth of over 10,900 meters (35,000 feet) in the Challenger Deep.
