This Rolex Sea Dweller Deep Sea D Blue James Cameron has a mechanical automatic self-winding Rolex caliber 3135 movement. It’s rhodium-plated and it’s constructed with 27 jewels, a straight-line lever escapement, and a shock absorber mechanism. It has bidirectional self-winding via a perpetual rotor. It has a monometallic balance that’s adjusted to 5 positions, and a free-sprung self-compensating Breguet balance spring. It includes a paramagnetic blue Parachrom hairspring, Microstella regulating screws, and a central hacking mechanism. This watch is incredibly strong, water and pressure-resistant, due to its exclusive Ringlock system. This radical case architecture enables the watch to resist the enormous pressure exerted by water at the depth of 3,900 meters (12,800 feet), equal to a weight of 3 tons on the watch. The system has a nitrogen-alloyed steel central ring, accompanied by a 5 mm?thick, domed sapphire crystal and a case back in grade 5 titanium. The mechanism oscillates at a frequency of 28,800 vph (4 Hz).
