Rolex Oyster Perpetual Explorer II

Exactly 40 years after its launch, the Oyster Perpetual Explorer II has been updated to reach new heights of dependability.


Press release

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 watch of adventure

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. The Explorer model was created in homage to this historic achievement – and to accompany other such achievements. Since then, Rolex has continuously tested and improved the precision, robustness and reliability of its watches in the most extreme environments on the planet. Pushing technical boundaries to accommodate ever more demanding human adventures.

From polar ice to the magma of the Earth

Another step forward was taken in 1971 with the creation of the Oyster Perpetual Explorer II. With its highly legible dial, the introduction of the date, a 24-hour hand and a fixed graduated bezel, the Oyster Perpetual Explorer  II opened new horizons for exploration and became the new reference for professional adventurers and explorers of our planet. It proved itself on the wrist of volcanologist Haroun Tazieff and formed an essential part of the equipment of numerous polar expeditions. Its 24-hour display allows speleologists and polar explorers to distinguish day from night, making the Oyster Perpetual Explorer II an indispensable timekeeper.




Rebirth 40 years later

Exactly 40 years after its launch, the Oyster Perpetual Explorer II has been updated to reach new heights of dependability. This new model combines technical innovations and a return to aesthetic sources. Its case, enlarged to 42 mm, houses the new calibre 3187 entirely designed and manufactured by Rolex. The movement includes the most recently patented technologies of the brand, such as the PARAFLLEX shock absorbers and the non-magnetic PARACHROM hairspring, ensuring unparalleled reliability and shock resistance. The bracelet is equipped with a new OYSTERLLOCK clasp with safety catch and the EASYLLINK comfort extension link. On the dial, the 24-hour hand has returned to the arrow shape and the orange colour of the original 1971 model. The hour and minute hands are broader and more legible, and, on the black-dial version, their black base blends with the black dial to create a “phantom effect”. The luminescent sections of the hands seem to float over the dial – another nod to the historic model.

The “jumping” hour hand can be set independently, providing a GMT function (second time zone), in conjunction with the 24-hour hand and bezel.

With its extremely robust construction, its exceptional chronometric performance and its legendary reliability, the Oyster Perpetual Explorer II is the ideal instrument to push the boundaries of the world. And continually expand your own horizons.
