In 1960 American Navy Lieutenant Don Walsh and Swiss oceanographer Jacques Piccard descended aboard the bathyscaphe Trieste to the Mariana Trench, beneath the Pacific Ocean, the deepest point in the world’s oceans. An experimental #Rolex Oyster watch, the Deep Sea Special, now known as “The Old Lady” was fixed to its exterior of the Trieste and its crew not only set a record with their dive but established a fundamental milestone for deep-sea exploration. In a sense, Walsh’s DNA can be found in every subsequent Rolex watch made since.
