Rolex is introducing the 904L steel version of its new-generation classic Oyster Perpetual Datejust 41 model, together with a white Rolesor version (a combination of 904L steel and 18 ct white gold) featuring an 18 ct white gold fluted bezel. A wide selection of dials is available for both versions. Like the yellow Rolesor and Everose Rolesor versions introduced in 2016, the new Datejust 41 watches are equipped with a redesigned 41 mm case and the new Rolex calibre 3235, at the forefront of watchmaking technology with its 14 patents, the new Chronergy escapement and a power reserve of approximately 70 hours.
Rolex’s Datejust is the archetype of the classic watch thanks to functions and aesthetics that never go out of fashion. Launched in 1945, it was the first self-winding waterproof chronometer wristwatch to display the date in a window at 3 o’clock on the dial, and consolidated all the major innovations that Rolex had contributed to the modern wristwatch until then.
Rolesor, a Marriage of Gold and Steel
Rolesor, the combination of gold and steel on a Rolex watch, has been a signature feature of the brand since 1933, when the name was registered. It is an auspicious meeting of two metals: one, noble and precious, attractive for its lustre and stability; the other, highly resistant, known for its strength and reliability. All of these qualities perfectly mirror the elegance and performance that come together in a Rolex watch.
The Oyster Case, Symbol of Waterproofness
The Oyster case of the Datejust 41, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness, proportion and elegance. Its characteristic middle case is crafted from a solid block of 904L steel. Its fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. Fitted with the Twinlock double waterproofness system, the winding crown screws down securely against the case. The crystal, with a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire.
Perpetual Calibre 3235
The Datejust 41 is equipped with calibre 3235, a new-generation movement entirely developed and manufactured by Rolex. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability. It incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. A n o p t i m i z e d b l u e Parachrom hairspring is fitted to the oscillator, the true heart of the watch. Patented and m a n u f a c t u r e d b y Rolex in an exclusive paramagnetic alloy, it is up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex overcoil ensures its regularity in any position. Calibre 3235 is equipped with a self-winding module via a Perpetual rotor. Thanks to its new barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3235 extends to approximately 70 hours.
Oyster and Jubilee Bracelets
The new Datejust 41 is available on an Oyster or Jubilee bracelet. Both these solid-link, 904L steel bracelets benefit from the new concealed attachment system beneath the bezel, which ensures seamless visual continuity between the bracelet and case. They are equipped with a folding Oysterclasp and also feature the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
Certification Like all Rolex watches, the Datejust 41 is covered by the Superlative Chronometer certification redefined by Rolex in 2015.
This exclusive designation testifies that the watch has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The precision of a Rolex Superlative Chronometer after casing 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.
