Exploration is a state of mind. It takes courage, resolve and an unquenchable thirst for discovery to always seek to go higher, farther, where no one has trod before. To mountain tops. To the extremities of the poles. To the depths of the Earth. To the edge of volcanic craters. The Oyster Perpetual Explorer model was born of this very state of mind. On 29 May 1953, Sir Edmund Hillary and Tenzing Norgay reached the summit of Mount Everest in the course of an expedition equipped with Rolex Oyster Perpetual watches.
