English: Rolex Deepsea Sea-Dweller 116660 Blue Dial. This Blue Dial model was released to honor James Cameron's 10,898.4 metres (35,756 ft) dive with the Deep-submergence vehicle (DSV) Deepsea Challenger to the Challenger Deep in 2012. The deep blue color on the top of the dial represents water closer to the surface, which slowly darkens to black as light is no longer able to penetrate the depth. The green text for "DEEPSEA" has the same color as the hull of the Deepsea Challenger submersible.
