Dive watches may already represent a robust and extremely functional timepiece for everyday use, but for those looking to push the limits, the new Oyster Perpetual Rolex Deepsea is the ultimate tool watch.
As far as dive watches go, the Rolex Oyster Perpetual Submariner, with waterproofness to a depth of 300 metres, will technically be more than enough for the average diver. However, if you are looking for a dive deep, then the new 2018 Rolex Deepsea will exceed your most exacting demands. Where the Rolex Submariner and Rolex Sea-Dweller will reach a depth of 300m and 1220m, respectively, the Rolex Deepsea, with its gorgeous D-blue dial, will withstand a depth of 3,900m. At this depth, the pressure is a massive 390 times greater than at the surface, illustrating the supremacy of Rolex in mastering waterproofness.
THE CASE OF THE OYSTER It is well-known that the Oyster case from Rolex was indeed designed to withstand water pressure but, at 3,900m, you can bet that the brand had to employ other modern innovations to ensure that the watch not only stays dry at that depth but remains functional. First is the Rolex-patented Ringlock System that is composed of three elements: a domed 5.5mm-thick sapphire crystal, a highperformance nitrogen-alloyed stainless steel ring, positioned inside the middle case of the watch, and a case back in Oystersteel and grade 5 titanium. Next, the Triplock winding crown is equipped with three seals, screwed down securely against the case,
completing the waterproofness system and guaranteeing watertight security akin to a submarine’s hatch.
Once a dive watch surpasses a certain depth underwater, the pressure becomes great enough that even though water molecules are kept out, smaller atoms like helium gas are forced into the watch. This may not prove to be a problem during the descent but gas will begin to force its way out during ascension, affecting the watch’s precision and reliability. In order to rectify the problem, Rolex developed and patented a helium escape valve in 1967, which allows the excess pressure built up in the watch case to escape during a diver’s decompression phase in a hyperbaric chamber.
For the new Rolex Deepsea, they have retained a gorgeous D-blue dial with the deep-blue to pitch-black gradient launched in 2014 on a commemorative version of the watch in tribute to James Cameron’s DEEP SEA CHALLENGE expedition. The 44mm Oystersteel case, however, has been redesigned to offer new lugs and sides, along with a broader Oyster bracelet. This new bracelet is also equipped with an Oysterlock safety clasp that prevents accidental opening and a double extension system that allows the watch to be worn comfortably over a diving suit up to 7mm thick. But what most patented Rolex Glidelock system that allows approximately 2mm increments up to around 20mm, thus giving the wearer an extremely
Yet another addition to the new Rolex Deepsea is a high-technology ceramic bezel. This Rolex-patented insert is extremely hard and corrosion-resistant, virtually scratchproof and its colour is unaffected by ultraviolet rays, ensuring perfect legibility even after prolonged use. As with the Rolex Sea-Dweller, the unidirectional rotatable bezel of the Rolex Cerachrom insert, where the numerals and the graduations are moulded in the ceramic and coloured with platinum using a PVD (Physical Vapour Deposition) process.
Descending below 1000m, sunlight will no longer be able to reach these depths and so Rolex used its proprietary Chromalight luminescent material to ensure legibility at all times. This material emits a long-lasting blue glow, lasting up to two times longer than traditional materials and can extend beyond eight hours.
THE PEARL HIDDEN WITHIN The new Rolex Deepsea is equipped with calibre 3235, a new-generation movement entirely developed and manufactured by Rolex. It incorporates the Chronergy escapement patented by Rolex, which dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. The oscillator has a blue Parachrom hairspring that is up to 10 times more precise than a traditional hairspring when subjected to shocks. And, thanks to its new barrel structure and the escapement’s superior 3235 extends to approximately 70 hours. Best of all, the watch, like all the modern Rolex watches, is Superlative Chronometer
All the innovations in the case to protect the watch at an insane depth, combined with the incredible precision of the movement, makes the new Rolex Deepsea the perfect utilitarian watch.
