The Rolex Deep-Sea D-Blue is part of the ultra-resistant divers models. Its development is part of many years of collaboration with professionals in the diving field. This piece carries a “Ringlock System” which is a feature that allows the crystal to withstand impressive pressure. In order to be able to develop this technology, Rolex used aerospace type materials such as nitrogen-alloyed steel and grade 5 titanium.
