The Rolex Oyster Perpetual Day-Date is a COSC certified, self-winding chronometer manufactured by Rolex. Initially presented in 1956, the Day-Date was the first watch to display the date, as well as the day, in its entirety. Rolex Oyster, a term often associated with the Rolex brand. Recognized as one of the most luxurious and prestigious watch brands in the world, no matter if you ask someone who knows watches well, or someone who doesn’t know much about them, most people know about Rolex. The Rolex Oyster Perpetual Submariner is a line of sports watches designed for diving and manufactured by Rolex, and are known for their resistance to water and corrosion. The first Submariner was introduced to the public in 1954 at the Basel Watch Fair.
Completely revised, the Oyster Perpetual range welcomes a new, 41 mm model: the Oyster Perpetual 41. The Oyster Perpetual 36 brings vibrant dials to the range. Both of these watches are fitted with calibre 3230.
Rolex presents the new generation of its Oyster Perpetual watches and brings a new model to the range, the Rolex Oyster Perpetual 41, as well as versions of the Oyster Perpetual 36 displaying dials in vivid colours. The light reflections on the case sides highlight the elegant profile of the Oyster case, which is made from Oystersteel. Measuring 41 mm or 36 mm respectively, it is fitted with a domed bezel.
One version of the Oyster Perpetual 41 has a novel configuration: its silver, sunray-finish dial is graced with hands and hour markers in 18 ct yellow gold. A second version is introduced with a bright black sunray-finish dial, and hands and hour markers in 18 ct white gold.
The Rolex Oyster Perpetual 36 is unveiled with a dynamic and vibrant new look, offering lacquer dials in five new colours: candy pink, turquoise blue, yellow, coral red and green.
The new generation Oyster Perpetual model has a Chromalight display: the hands and hour markers are coated or filled with a luminescent material that emits a long-lasting blue glow in dark conditions.
The Oyster Perpetual 41 and the new versions of the Oyster Perpetual 36 are equipped with calibre 3230, a movement at the forefront of watchmaking technology, launched by Rolex this year.
Like all Rolex watches, the Oyster Perpetual 41 and Oyster Perpetual 36 carry the Superlative Chronometer certification, which ensures excellent performance on the wrist.
THE ESSENCE OF THE OYSTER
Watches in the Oyster Perpetual range are direct descendants of the original Oyster, the world’s first waterproof wristwatch, on which Rolex has built its reputation since 1926. These watches benefit from all the fundamental features of the Oyster Perpetual collection – excellent chronometric precision, a waterproof Oyster case, and self-winding of the movement via a Perpetual rotor. Displaying hours, minutes and seconds, made exclusively of Oystersteel and featuring a sophisticated finish, these are chronometer wristwatches in their purest form.
THE OYSTER CASE, SYMBOL OF WATERPROOFNESS
A paragon of robustness and elegance, the Oyster case of the Oyster Perpetual 41 and Oyster Perpetual 36 is guaranteed waterproof to a depth of 100 metres (330 feet). Its middle case is crafted from a solid block of Oystersteel, a particularly corrosion-resistant alloy. The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal is made of virtually scratch-proof sapphire. The waterproof Oyster case provides optimum protection for the watch’s movement.
PERPETUAL CALIBRE 3230
The Oyster Perpetual 41 and the new versions of the Oyster Perpetual 36 are equipped with calibre 3230, a movement entirely developed and manufactured by Rolex, launched by the brand this year. At the forefront of watchmaking technology, this self-winding mechanical movement led to the filing of several patents, and offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.
Calibre 3230 incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic fields. The movement is fitted with an optimized blue Parachrom 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 calibre’s regularity in any position. The oscillator is fitted on the Rolex-designed and -patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance.
Calibre 3230 is equipped with a self-winding module via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, its power reserve extends to approximately 70 hours.
The Oyster Perpetual 41 and the Oyster Perpetual 36 are fitted with an Oyster bracelet in Oystersteel. Developed at the end of the 1930s, this three-piece link bracelet is known for its robustness.
On this particular Oyster bracelet, the tops of the links are satin-finished, while the sides are polished. It is fitted with a folding Oysterclasp and the Easylink comfort extension link, developed by Rolex, that allows the wearer to easily adjust the bracelet length by approximately 5 mm. It is the first time that this extension system has been used on a bracelet for the Oyster Perpetual range.
In addition, a concealed attachment system ensures seamless visual continuity between the bracelet and case.
SUPERLATIVE CHRONOMETER CERTIFICATION
Like all Rolex watches, the Oyster Perpetual 41 and Oyster Perpetual 36 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.
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.
