During this solo expedition Cameron wore his Rolex Deepsea D-Blue on his wrist while three large 51mm watches, made specifically for the expedition, were strapped to the outside of his submersible for experimentation. He reached a world-record of 35,787 feet while the Rolex watches resisted 12 tons of pressure on their crystal and reemerged unharmed, keeping time perfectly for the seven hour dive. The redesigned timepiece showcases this feat of exploration through its watch face, a blue color which fades from light to dark to represent the depth of the oceans. On its dial the word Deepsea is lit in a bright green color, the same shade as Cameron’s submersible. Like the original Deepsea watch, this special edition piece has a helium escape valve for deep-sea diving, a ringlock pressure resistance system up to 3,900 meters and titanium case backing.
