TIMELESS STYLE
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 rst 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 . Aesthetically , the Datejust has spanned eras while retaining the enduring codes that today still make it one of the most recognized and recognizable of watches .
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 regis- tered . 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 . On white Rolesor models , the middle case and bracelet are in 904L steel , while the uted bezel is in 18 ct white gold . 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 uted 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 scratch- proof sapphire . The waterproof Oyster case provides optimum protection for the Datejust 41 ’ s highprecision movement .
An optimized blue Parachrom hairspring is tted to the oscillator , the true heart of the watch . Patented and manufactured by 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 ef ciency , 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 bene t 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 .
SUPERLATIVECHRONOMETER CERTIFICATION
Like all Rolex watches , the Datejust 41 is covered by the Superlative Chronometer certi cation rede ned by Rolex in 2015 . This exclusive designation testi es 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 certication applies to the fully assembled watch , after casing the movement , guaranteeing superlative performance on the wrist in terms of precision , power reserve , waterproofness and selfwinding . 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 .
PERPETUAL CALIBRE 3235
The Datejust 41 is equipped with calibre 3235 , a newgeneration movement entirely developed and manufactured by Rolex . This self-winding mechanical movement is at the forefront of the art of watchmaking . A consummate demonstration of Rolex technology , with 14 patents , it offers fundamental gains in terms of precision , power reserve , resistance to shocks and magnetic elds , convenience and reliability . It incorporates the new Chronergy escapement patented by Rolex , which combines high energy ef ciency with great dependability . Made of nickel-phosphorus , it is also insensitive to magnetic interference .
