In 1960, the intrepid oceanographers Jacques Piccard and Don Walsh performed the legendary dive to the deepest point on Earth, aboard the bathyscaphe Trieste, a kind of submarine perfected for expeditions of great sea depths. At the time, the adventurers ventured on a mission that lasted about 9 hours, and they reached the incredible mark of 10,916 meters of depth, an extreme and extraordinary experience. The point, then, was christened Challenger Deep.
After 52 years of the great achievement, acclaimed film director James Cameron, in partnership with National Geographic, decided to return to the depths of the Earth, more precisely to the Trench of the Marianas, in an attempt to reach 11,000 meters deep. Located in the Pacific Ocean, the point marks the boundary between the tectonic plates of the Pacific and the Philippines and had never been accessed given its immense depth. It is said that scientists have more knowledge about the surface of Mars than about the species and conditions of the ‘Challenger Deep’. And so, this time the location would be filmed with high resolution 3D cameras and would collect samples for research in the field of marine biology, microbiology, geology and geophysics.
This new expedition, called the Rolex replica Deepsea Challenge, used a new submersible, specially designed for the mission and also had the partnership of Rolex, since it needed a clock, a time gauge, that could accurately capture all the details of the maritime operations.
Rolex replica emerged as a natural partner, since its expertise had already been enshrined in the first dive (1960) with Deep Sea Special, an experimental Oyster model that was coupled to the hull of Trieste. This time, what seemed like a mission impossible for any other team, was not an obstacle for Rolex replica watches engineers – to build an even more robust watch, capable of withstanding the highest pressures on the seabed in just 5 weeks .
The constant quest for perfection resulted in the Rolex Deepsea Challenge prototype, which was tied to the robotic arm of the James Cameron submersible. The watch worked perfectly throughout the dive, confirming Rolex’s status as the leading brand in precision and watertightness. The Deepsea Challenge expedition with James Cameron reached the deepest point on Earth on March 26, 2012, reaching 10,908 meters.
Taking into account the diameter of the 3135 automatic rope mechanical movement and the Rolex replica Deepsea dial, the engineers calculated the necessary technical dimensions that could withstand about 17 tons of weight on the sapphire crystal and 23 tons on the back of the box, suffered at depths of up to 15,000 meters. In addition, the watch should maintain the aesthetic and unmistakable Rolex design.
The replica Rolex Deepsea Challenge Oyster box is 51.4 mm in diameter and 28.5 mm thick and was produced with three different materials: 904L steel for the central part, an alloy steel and nitrogen and titanium grade 5, which was used to the back of the carton, which should withstand higher pressures.
The bigger proportions of the box made the crown and the telescope also be adapted to the new project and received special attention of the designers, since they are part of the whole triplock system of sealing. A new laser technology has made the engraving of the logo and the specifications of the watch in black, reinforcing the high-tech appeal of the watch.
The black bottom dial of the Rolex Deepsea replica watches was used as the base, with only depth markings changed to 39,370 ft = 12,000 m. Hour markers and pointers received the Chromalight blue luminescent treatment for better reading of the information in the dark background of the seabed.
Like the first Deep Sea Special model, the sapphire crystal that lines the dial should be reinforced. At 14.3 mm thick, the new crystal proved to be robust enough and offered excellent dial viewing.
James Cameron’s pioneering spirit of adventure and all the details of the Deepsea Challenge expedition are roaring the world through exhibitions and lectures, where the two prototype watches – the 1960 Rolex Deepsea Special and the replica Rolex Deepsea Challenge – will also be on display.
