ROLEX is introducing the new generation of its Oyster Perpetual Submariner and Oyster Perpetual Submariner Date. Both timepieces now feature a redesigned, slightly larger 41 mm case – whose profile is highlighted by the light reflections from the case sides and lugs – and are fitted on a remodelled bracelet. They are equipped with movements at the forefront of watchmaking technology – the Submariner with calibre 3230, unveiled by the brand this year, and the Submariner Date with calibre 3235, offering both time and date functions, and used in the Submariner range for the first time.
True to its aesthetic heritage, the new Submariner in has a black dial
and rotatable bezel with matching Cerachrom insert. A yellow version (combining Oystersteel and 18 carat yellow gold) of the Submariner Date presents a royal blue dial with a rotatable bezel and a blue insert. Two versions of the Submariner Date, one in Oystersteel and the other in 18 carat white gold, bring distinctive colour combinations, with the dial and Cerachrom insert in different hues. The first watch blends a black dial with a green bezel, while the second proposes a black dial and a blue bezel.
Like all Rolex watches, the Oyster Perpetual Submariner and Submariner Date are covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria. These certification tests apply to the fully assembled watch, after casing the movement, guaranteeing superlative
performance on the wrist in terms of precision, power reserve, waterproofness and self-winding.
The precision of a Rolex Superlative Chronometer is of the order of −2/+2 seconds per day (!!!), or more than twice that required of an official chronometer (COSC = -4/+6 seconds per day).
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 new-generation Submariner and Submariner Date are equipped respectively with calibre 3230 – launched this year – and calibre 3235, movements entirely developed and manufactured by Rolex. At the forefront of watchmaking technology, these self-wind- ing mechanical movements led to the filing of several patents, and offer fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.
Calibres 3230 and 3235 incorporate the escapement (Frequency: 28,800 A/h = 4 Hz), patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic fields. The movements are fitted with an optimized blue hairspring, manufactured by Rolex in an exclusive paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks. The blue Parachrom hairspring is equipped with a Rolex overcoil, ensuring the calibres’ regularity in any position. The oscillator is fitted on the Rolex- designed and -patented high-performance shock absorbers, increasing the movements’ shock resistance.
Both calibres are equipped with a self-winding module via a Perpetual rotor. Thanks to their barrel architecture and the escapement’s superior efficiency, the movements’ power reserve extends to approximately 70 hours.
The Oyster bracelet on these new versions is equipped with a Rolex-designed and -patented folding safety clasp, which prevents accidental opening. It also features the Rolex extension system, designed and patented by the brand. This particularly inventive mechanism comprises a rack located under the clasp cover and a toothed sliding link that locks into the chosen notch. The Rolex Glidelock on the Oyster bracelet has 10 notches of approximately 2 mm, allowing the length of the bracelet to be adjusted easily, and without tools, up to some 20 mm.
