FERNANDO CORREIA DE OLIVEIRA Among collectors, the world of the Submariner is huge and the evolution of the model is the subject of books and Internet forum debates – calibres, chronometer versions or not, hand style, crown size, dial colour, signatures, luminescent material used, etc. In 2003, Rolex commemorated 40 years of the Submariner, giving it an even more waterproof case, a new calibre and some aesthetic changes. The production of this commemorative model Rolex Submariner-Date anniversary edition (16610 LV) ended in 2010. In 2008, a new case from the Rolex GMT II began to be used in the Submariner- Date, with a cerachrom bezel. “Brother” to the Submariner, in 1971 Rolex created the Sea-Dweller, a version with a thicker case and dial glass, with a date and without the so-called “eye of Cyclops”. Equipped with a helium escape valve, the first version guaranteed water resistance up to 1,220 metres (4,000 feet). The popularity and reliability of the two models benefitted from the fact that the French professional diving company, Comex, used the Rolex Submariner and Sea Dweller in their operations from the late 1960s. The Rolex Oyster Perpetual Sea-Dweller Submariner 2000 (2000 feet = 610 m), available from 1967, was even developed specifically for Comex. It was then that the Submariner and Sea-Dweller became autonomous. In 1988, a team of professional Comex divers beat the offshore diving record while doing exercises for a pipeline connection over 534 metres deep in the Mediterranean. The team wore Rolex Sea-Dwellers. In 1992 the Comex diver, Theo Mavrostomos, established a record of 701 metres (2,300 feet) in a hyperbaric chamber offshore. It took 43 days to complete the dive. The watch used in this scientific experiment, where he breathed a mixture of hydrogen, helium and oxygen (hydreliox) was a Rolex SeaDweller 16600 resistant up to 1,220 m (4,000 feet). In late 2008, the Sea-Dweller was replaced by the DeepSea Sea-Dweller. With a 44 mm case, it is resistant up to 3,900 metres (12,800 feet). The use of the patented Triplock safety system in the crown, the unidirectional rotatable bezel, protecting against accidental handling and the rapidly-adjustable bracelet clasp are technical developments that have accompanied the Submariner and the Sea-Dweller, later imitated by other brands. Rolex diving watches have been part of the most important underwater expeditions. In the 1950s, Rolex ran extremely tough tests on one model, the Deep Sea Special, using the knowledge acquired from previous models. In 1960, the experimental bathyscaphe, the Trieste, succeeded in descending to the Mariana Trench, the deepest known point on the Earth’s surface. With Lieutenant Don Walsh at the helm, accompanied by Professor Jacques Piccard, the Trieste managed to go where no-one had ever been. The expedition used Deep Sea Special watches. In 1967, the Oyster Perpetual Sea-Dweller was launched, waterproof up to 610 metres (2,000 feet), with a helium escape valve in the case. Today, this line of diving watches has models resistant up to 3,900 metres deep (12,800 feet), which is the case of the most recent, the Sea-Dweller DEEPSEA, presented in 2008 at the Basel Fair. This is the most waterproof, mass-produced mechanical wristwatch. Rolex tests it at 4,875 metres (15,994 feet), to guarantee the 25 per cent safety margin required by ISO standard 6425, which regulates professional diving watches. Finally, on 26th March 2012, the film director and National Geographic Society explorer, James Cameron, went down to the Mariana Trench, making the first solo dive to the deepest place on the planet, the third man ever to visit the zone following the Trieste exploration in 1960. On the expedition, and on the outside of the submarine, there was a prototype Rolex Oyster Perpetual Date Sea-Dweller Deepsea Challenge, which went down to 10,898.4 metres (35,756 feet). This prototype is prepared to resist depths of up to 12,000 metres (39,370 feet). On his wrist, Cameron used the mass-produced Rolex Sea-Dweller Deepsea. Only one passenger went on both the 1960 and 2012 expeditions to the Mariana Trench: Rolex watches. Submariner Date 41
