Created in 1953, the Submariner was the first divers’ watch waterproof to a depth of 100 metres (330 feet). Since that time it has expanded its horizons well beyond the element of its birth. At home in the depths of the oceans, it long ago conquered terra firma as a symbol of the watch of action. On land as at sea, this emblematic watch has irresistible seductive power.
BEZEL WITH HIGHLY RESISTANT CERACHROM INSERT
The unidirectional rotatable bezel of the Submariner is equipped with a Rolex-patented Cerachrom insert – in black, blue or green, depending on the version. The 60-minute graduation allows divers to monitor their time underwater for their safety. The insert, made of an extremely hard and corrosionresistant ceramic, is virtually scratchproof and its colour is unaffected by ultraviolet rays. The graduations and the numerals are moulded in the ceramic and coloured with gold or platinum using a PVD (Physical Vapour Deposition) process. The bezel’s knurled edge offers excellent grip when manipulating the bezel to set dive time, even when wearing gloves.
In addition to its functions and its intrinsic technical qualities, the Submariner bezel contributes to the model’s very strong visual identity.
The Submariner is an extremely legible watch which is at home in the dark depths of the oceans. The Chromalight hour markers and hands are filled with a luminescent material emitting a longlasting blue glow. On the bezel, the zero marker of the graduation, in the form of a triangle, is visible in the dark thanks to a capsule containing the same luminescent material.
THE SUBMARINER, SUPERLATIVE CHRONOMETER
Like all Rolex watches, each Submariner is certified as a Superlative Chronometer. This exclusive designation attests that it has successfully undergone a series of tests conducted by Rolex in its own laboratories and according to its own criteria, which exceed watchmaking norms and standards. These tests are carried out on the fully assembled watch, in order to guarantee its superlative performance on the wrist.
The precision of every movement – officially certified as a chronometer by COSC (Swiss Official Chronometer Testing Institute) – is, therefore, tested a second time by Rolex after being cased, to ensure that it meets criteria for precision that are far more exacting than those for an official Oyster Perpetual chronometer. The tolerance for the average rate of a Rolex Superlative Chronometer after casing is of the order of −2/+2 seconds per day. Its precision is tested by Rolex using an exclusive methodology that simulates the conditions in which a watch is actually worn and is much more representative of real-life experience.
The certification testing is carried out using state-of-the-art equipment specially developed by Rolex. The entirely automated series of tests also checks the waterproofness, the self-winding capacity and the power reserve of 100 per cent of Rolex watches. These tests systematically complement the qualification testing upstream during development and production that ensures the watches’ reliability, robustness, and resistance to magnetic fields and shocks.
The unique way in which Rolex watches are designed, manufactured and tested, together with the exclusive innovations from which they benefit, push back the limits of performance for mechanical watches and make the brand the benchmark for watchmaking excellence. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
THE OYSTER CASE, SYMBOL OF WATERPROOFNESS
The Submariner’s Oyster case, guaranteed waterproof today to a depth of 300 metres (1,000 feet), is a paragon of robustness and reliability. The characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel, or 18 ct gold. The fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The winding crown, fitted with the Triplock triple waterproofness system and protected by a crown guard that is an integral part of the middle case, screws down securely against the case, offering watertight security akin to a submarine’s hatch.
The crystal, with a Cyclops lens fitted on the Submariner Date for easy reading of the date, is made of virtually scratchproof sapphire. The waterproof Oyster case provides the Submariner’s high-precision mechanical movement with optimal protection.
