When the Hydra VIII mission by Comex (Compagnie Maritime d'Expertises) set the world open-sea diving record at a depth of 534 metres in 1988, the watch that accompanied the divers on their mission was a Rolex Oyster Perpetual Sea-Dweller chronometer. This model was standard equipment for the world leader in marine engineering.
It was the only watch the firm’s elite divers fully trusted on their saturation dives to great depths – when precise timing is of vital importance at every stage – and the watch they had used on thousands of successful underwater missions in extreme conditions. Thanks to its Rolex-patented helium valve, this legendary watch was instrumental in the conquest of the deep. It is being reintroduced in an updated version that benefits from Rolex’s latest technical innovations while remaining faithful to the iconic aesthetics of the original model.
