Rolex Deepsea Sea-Dweller D-Blue Dial Watch
We've seen waterproof watches before, but this is ridiculous. Built to commemorate James Cameron's solo dive to the bottom of the Mariana Trench, the Rolex Deepsea Sea-Dweller D-Blue Dial Watch sports a Ringlock case that enables it to stay waterproof down to a staggering 12,800 feet. Other features include a two-color gradient dial that goes from blue to black — signifying the change in water color during the historic dive — as well as a helium escape valve for decompression and a blue Chromalight display that ensures readability in even the darkest of environments.
