Rolex was there when humans wanted to descend to the deepest spot on Earth. Now that James Cameron wants to go deeper than that, Rolex is going to tag along too.

The Deep Sea Special joined the Trieste back in 1960, with a monstrously thick lens design that let it survive to a depth of 35,800 feet. James Cameron will be wearing Rolex's new Deepsea Challenge, named after the Deepsea Challenger sub he'll be using, which will feature a more contemporary, but impressively thick design that can survive depths of up to 40,000 feet.
