Rolex collaborated with professional scuba divers to create the Deepsea, which is waterproof to a depth of 12,800 feet. The case is made of Oystersteel, which is a part of the super-alloy 904L stainless-steel family used in the aerospace industry. The dial on this version of the Deepsea fades from blue to black, which is the color gradiation that film director James Cameron saw during his dive to the ocean's deepest spot, the
Mariana Trench. Rolex designed this version of the Deepsea to commemorate Cameron's experience. He made it 35,787 feet below the surface.
