HOW ROLEX CONQUERED THE DEEP

The ultra-resistant divers’ models engineered by Rolex for the conquest of the deep: waterproof to a depth of 4,000 feet (1,220 metres) for the Rolex Sea-Dweller and 12,800 feet (3,900 meters) for the Rolex Deepsea, they are the result of decades of collaboration with diving professionals.
