Sophisticated and self-assured, the Rolex Oyster Perpetual Datejust in 31 mm sizing, presented in 18ct Everose gold radiates its outgoing personality through sparkling diamonds and the nuanced hues of Everose.

The Datejust is the archetype of the classic watch according to Rolex, thanks to functions and aesthetics that never go out of fashion. At its launch 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 – hence its name. It consolidated all the major innovations that the brand had contributed to the modern wristwatch until then – chronometric precision (first chronometer certificates granted to a Rolex wristwatch as of 1910), waterproofness (Oyster case unveiled in 1926) and self-winding (mechanism via Perpetual rotor patented in 1931).

The Datejust’s Oyster case, 31, 36 or 41 mm in diameter and guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and elegance.

The middle case is crafted from a solid block of Oystersteel or from 18 ct yellow, white or Everose gold. 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 bezel can be smooth, domed, fluted or set with diamonds. The crystal, with a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses.

The Datejust 31 is available on a three-piece link Oyster bracelet equipped with a Rolex-designed, patented Oysterclasp, or on a five-piece link Jubilee bracelet – created in 1945 especially for the Datejust – or a three-piece link President bracelet, both of which are fitted with a concealed Crownclasp, developed by the brand and patented.
