The new rolex deepsea sea-dweller d-blue dial watch replica celebrates the partnership between Rolex and the historic 2012 DEEPSEA CHALLENGE exped ition to the deepest point in the ocean. This scientiﬁc endeavour was undertaken by explorer and ﬁlm-maker James Cameron, who wore his trusted Rolex Deepsea as he became the ﬁrst person to reach the Challenger Deep as a solo pilot. He successfully navigated the unique DEEPSEA CHALLENGER submersible he co-designed to a depth of 10,908 metres (35,787 feet), where he explored the ocean trench, took samples and captured the ﬁrst-ever high-resolution images of the deepest sea ﬂoor.
The last trickle of light from the surface disappears into the abyss. This is the underwater twilight zone, where deep blue fades to pitch black and the ocean sinks into a realm less known to man than the surface of the moon. This threshold to the ocean’s fathomless reaches inspired the blue to black gradient dial of the newest version of the Rolex Deepsea, the professional divers’ watch waterproof to the extreme depth of 3,900 metres (12,800 feet).
On the outside of the submersible, afﬁxed to the robotic arm and the hull, were three experimental Rolex Deepsea Challenge watches, specially engineered by Rolex to withstand the most colossal water pressure on the planet. These watches, designed with the exact same architecture as the rolex deepsea sea dweller replica, only much larger, provided the ultimate proof of the model’s waterproofness and resistance to extreme pressure.
A few weeks earlier, as Cameron was putting his submersible through a trial run off the coast of Papua New Guinea, a standard Rolex Deepsea was attached to the sub’s hydraulic arm for a real-life dive to 4,000 metres (13,120 feet). Under pressure that would crush a nuclear submarine like a can of soda, Rolex’s professional divers’ watch kept its cool.
NEW GRADIENT DIAL
The new version of the rolex sea dweller deepsea 16660 replica watch sports a deep blue to pitch-black gradient dial, reminiscent of the ocean’s twilight zone where the last trickle of light from the surface disappears into the abyss. This new “D-blue” dial echoes the journey to the deepest point in the ocean undertaken by ﬁlm-maker and explorer James Cameron in 2012 with his DEEPSEA CHALLENGE expedition, partnered by Rolex and National Geographic. As a tribute to this partnership, the “DEEPSEA” marking on the new dial adopts the colour of James Cameron’s green submers ible as it is perceived underwater.
The Rolex Deepsea’s waterproof Oyster case is hewn from a solid block of 904L stainless steel superalloy. This particularly corrosion-resistant grade of steel is greatly valued in the chemical and aerospace industry for its high perform ance. The Oyster case holds the three components of the Ringlock System. The Triplock winding crown, equipped with three seals, screws down securely against the case, completing the waterproofness system and offering watertight security akin to a submarine’s hatch.
The Rolex Deepsea owes its exceptional strength, waterproofness and pressure resistance to the exclusive Ringlock System. This innovative case architecture patented by Rolex enables the watch to resist the massive pressure exerted by water at the depth of 3,900 metres (12,800 feet), equivalent to a weight of approximately 3 tonnes on the watch. Its construction is based on three elements:
– A nearly indestructible nitrogen- alloyed stainless steel compression ring is pos itioned inside the watch case, around the movement, to provide support for the crystal and the case back. The backbone of the watch, it can withstand pressure that would crush a submarine.
– The watch face is protected by a dense, 5 mm dome-shaped sapphire crystal, made of high-purity aluminium oxide.
– Finally, the case back in grade 5 titan ium is held tight against the high-performance compression ring by a screw-down ring in 904L stainless steel. The almost imperceptible ﬂexibility of grade 5 titanium allows the water pressure to strengthen the hermetic seal of the case as depth increases, by for cing the components tighter and tighter together.
HELIUM ESCAPE VALVE
The Rolex Deepsea’s Oyster case is equipped with a helium escape valve. Patented by Rolex in 1967, this safety valve acts as a miniature decompression chamber for the watch and is essential for deep-sea saturation diving. During the decompression phases that professional divers undergo in hyperbaric chambers, the helium valve automatically regulates the excess pressure trapped inside the watch case without compromising the waterproofness of the watch.
CERACHROM BEZEL INSERT
The unidirectional rotatable bezel of the Rolex Deepsea is ﬁtted with a 60- minute graduated black Cerachrom insert that allows divers to safely monitor their time underwater and their decompression stops. The insert, made of an extremely hard and corrosion -resistant ceramic, is virtually scratchproof and its colour never fades. The numerals and the graduations are engraved in the ceramic and coated with platinum using a PVD (Physical Vapour Deposition) process patented by Rolex, for optimal legibility and durability. The bezel’s knurled edge offers excellent grip when setting dive time, even with diving gloves.
Great attention was paid to the legibility of this Professional divers’ watch. The Chromalight hour markers and hands are ﬁlled with a luminescent material emitting a long-lasting blue glow – lasting up to twice as long as traditional materials. On the bezel, the zero marker of the gradu ation, in the form of a triangle, is visible in the dark thanks to a capsule containing the same luminescent material.
SAFETY CLASP AND EXTENSION SYSTEM
The Rolex Deepsea’s Oyster bracelet is equipped with an Oysterlock safety clasp that prevents accidental opening, and with a double extension system that allows the watch to be worn comfortably over a diving suit up to 7 mm thick. The Fliplock extension link extends the bracelet by 26 mm, while the Rolex Glidelock system allows ﬁne adjustments of the bracelet length in 2 mm increments for a total of approximately 20 mm. Neither of them Rolex Replica Watches the use of any tools.
