Rolex Lady-Datejust 31 31 mm 278241ARDVIJ Steel/Rose Gold Aubergine Rolex Lady-Datejust 31 31 mm 278241ARDVIJ Steel/Rose…

The Rolex Lady-Datejust is one of the most storied watches in horological history, introduced in 1957 as the first self-winding, waterproof, and date-displaying wristwatch designed specifically for women. Over the decades it has evolved in refinement while retaining the instantly recognizable Datejust DNA—the fluted or domed bezel, the date window at three o'clock, and the graceful proportions that sit perfectly on a variety of wrist sizes. The 31mm case size occupies the sweet spot in the Lady-Datejust collection, offering a slightly more substantial presence than the classic 28mm without departing from the watch's feminine character.

Reference 278241ARDVIJ showcases Rolex's mastery of two-tone design by pairing Oystersteel—the brand's proprietary corrosion-resistant alloy—with 18k Everose gold, the exclusive rose-gold formula developed by Rolex that resists fading over time. The smooth domed bezel in Everose gold frames the 31mm case with understated elegance, eschewing the more flashy fluted or diamond-set options in favor of clean, sculptural lines that complement rather than compete with the striking dial.

The aubergine dial is the undisputed centerpiece of this reference. A deep, complex purple with warm undertone—evoking ripe eggplant or aged burgundy—it is one of the rarest and most sought-after dial colors in the Lady-Datejust lineup. Roman numeral hour markers rendered in a matching or contrasting finish add classical gravitas, lending the watch a timeless, almost jewel-like quality that transitions seamlessly from boardroom to black-tie occasion. The date aperture at three o'clock carries Rolex's signature Cyclops lens on the crystal, magnifying the date 2.5x for instant legibility.

Powering the watch is an automatic movement, meaning the rotor winds the mainspring through the natural motion of the wearer's wrist. Water resistance is rated to 100 metres (330 feet) courtesy of the screw-down Twinlock crown and the Oyster case architecture, making this not merely a dress piece but a robustly built companion for daily life. The five-piece Jubilee bracelet—introduced alongside the very first Datejust in 1945—completes the package with its intricate link construction that drapes fluidly and remains one of the most comfortable metal bracelets in watchmaking.
