A professional diver’s watch from Rolex with water resistance up to 3,900 metres. Designed for the challenging conditions that deep sea divers endure, the Deepsea made its successful debut in 2008. This model can trace its pedigree back to the 1950s and 1960s to legendary models such as the Submariner. The 44 mm case is in extra tough 904L stainless steel, with a depth defying thickly domed sapphire crystal as well as a unidirectional rotatable bezel with a 60-minute graduated black Cerachrom insert.
