DESCRIPTION

  • AN ICONIC WATCH

    Rolex is introducing the new generation of the Oyster Perpetual Datejust 31, with redesigned case sides and lugs. In 18 ct white, yellow or Everose gold, the new versions are equipped with calibre 2236, at the forefront of watchmaking technology. Amongst the many combinations available, one, in 18 ct white gold, is fitted with a white mother-of-pearl dial and a diamond-set bezel. Another, in 18 ct yellow gold, features a malachite dial with a Roman VI and IX in 18 ct yellow gold set with diamonds, and a version in 18 ct Everose gold is introduced with a diamond-paved dial inlaid with pink mother-of-pearl butterflies.

    Like all Rolex watches, the new-generation Datejust 31 carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.

    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 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. Aesthetically, the Datejust has spanned eras while retaining the enduring codes that today still make it one of the most recognizable of watches.

    THE OYSTER CASE, SYMBOL OF WATERPROOFNESS

    The Oyster case of the Datejust 31, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and elegance. Its refined middle case is crafted from a solid block of 18 ct yellow, white or Everose gold. 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 winding crown, fitted with the Twinlock double waterproofness system, 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. The waterproof Oyster case provides optimum protection for the Datejust 31’s high-precision movement.

    PERPETUAL CALIBRE 2236

    The new Datejust 31 is equipped with calibre 2236, a new-generation self-winding mechanical movement entirely developed and manufactured by Rolex. Fitted with a Syloxi hairspring in silicon, patented by Rolex, calibre 2236 offers a superlative level of chronometric performance. Insensitive to magnetic fields, the Syloxi hairspring provides great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. Its patented geometry ensures its regularity in any position. Calibre 2236 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 55 hours. This calibre equips the Datejust 31 for the first time.

    PRESIDENT BRACELET

    The new Datejust 31 watches are fitted on a President bracelet, which benefits from a concealed attachment system, ensuring seamless visual continuity between the bracelet and case. The bracelet also includes ceramic inserts inside the links to enhance its flexibility and longevity, and has a concealed folding Crownclasp.

    SUPERLATIVE CHRONOMETER CERTIFICATION

    Like all Rolex watches, the Datejust 31 is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that each 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 certification applies 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 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.
