The Submariner’s rotatable bezel is a key functionality of the watch. Its 60-minute graduations allow a diver to accurately and safely monitor diving time and decompression stops. The dial’s luminescent Chromalight display is an innovation that improved visibility in dark environments, an essential feature for divers. Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential
