The purest expression of the Oyster concept, the Oyster Perpetual provides a clear and accurate time display.
The Oyster Perpetual is the direct descendant of the original Oyster launched in 1926, the first waterproof wristwatch in the world and the foundation on which Rolex has built its reputation. It comprises the renowned Oyster case and a mechanical self-winding movement via Perpetual rotor. Certified as a Superlative Chronometer, the Oyster Perpetual is endowed with all the fundamental attributes of the Oyster Perpetual collection. The pure and elegant lines of this timepiece set it apart with universal and classic style.
This timeless watch has been perpetually renewed to take on the brand’s latest technical innovations. Varied and eye-catching new dial colours and designs ensure that it always sports a contemporary look.
THE OYSTER PERPETUAL, SUPERLATIVE CHRONOMETER CERTIFIED
Like all Rolex watches, the Oyster Perpetual is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation attests that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories and 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 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 precision of every movement – officially certified as a chronometer by the Swiss Official Chronometer Testing Institute (COSC) – is tested a second time by Rolex after being cased, to ensure that it meets criteria for precision that are far stricter than those of the official certification. The tolerance for the average rate of a Rolex Superlative Chronometer 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 Superlative Chronometer certification testing is carried out after casing 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 during development and production, in order to ensure the watches’ reliability, robustness, and resistance to magnetic fields and shocks.
THE OYSTER CASE, SYMBOL OF WATERPROOFNESS
The Oyster Perpetual’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. The characteristically shaped 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 grants only certified Rolex watchmakers access to the movement. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Oyster Perpetual’s movement.
PERPETUAL CALIBRES 2232 AND 3230
The Oyster Perpetual models are equipped with either calibre 2232 (Oyster Perpetual 28, Oyster Perpetual 31 and Oyster Perpetual 34), or calibre 3230 (Oyster Perpetual 36 and Oyster Perpetual 41), self-winding mechanical movements entirely developed and manufactured by Rolex. Consummate demonstrations of technology, these movements carry a number of patents. They offer fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.
The oscillator of calibres 2232 and 3230 has a balance wheel with variable inertia regulated extremely precisely via gold Microstella nuts. It is held firmly in place by a height-adjustable traversing bridge enabling very stable positioning to increase shock resistance. The oscillator is also fitted on high-performance Paraflex shock absorbers, designed and patented by Rolex.
Calibre 2232 incorporates a Syloxi hairspring in silicon, which is patented and manufactured by the brand. Calibre 3230 features an optimized version of the blue Parachrom hairspring, manufactured by Rolex in an exclusive paramagnetic alloy. Both hairsprings are insensitive to magnetic fields, offer great stability in the face of temperature variations and remain up to 10 times more precise than a traditional hairspring in case of shocks.
The geometry of the Syloxi hairspring found in calibre 2232 ensures the regularity of the movement in any position. The blue Parachrom hairspring of calibre 3230 is fitted with a Rolex overcoil that offers the same level of performance.
Calibre 2232 has a paramagnetic nickel-phosphorus escape wheel. Calibre 3230 incorporates the Chronergy escapement, made of the same alloy and patented by Rolex, which combines high energy efficiency with great dependability and is also insensitive to magnetic fields.
Calibres 2232 and 3230 are fitted with a self-winding module featuring a Perpetual rotor, which ensures continuous winding of the mainspring by harnessing the movements of the wrist to provide constant energy. Calibre 2232 offers a power reserve of approximately 55 hours, while the power reserve of calibre 3230 extends to approximately 70 hours thanks to its barrel architecture and the escapement’s superior efficiency.
The Oyster Perpetual’s movements will be seen only by certified Rolex watchmakers, yet they are beautifully finished and decorated in keeping with the brand’s uncompromising quality standards.
THE OYSTER BRACELET
Oyster Perpetual watches are paired with a three-piece link Oyster bracelet in Oystersteel, which is very secure and comfortable to wear. The bracelet is equipped with a folding Oysterclasp designed by Rolex, as well as the Easylink comfort extension link developed by the brand, which allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
A concealed attachment system on the bracelet ensures seamless visual continuity between the bracelet and case.
