Rolex Datejust Lady 31 31 mm 278240MDBJ Steel/White Gold/Diamonds Meteorite Rolex Datejust Lady 31 31 mm 278240MDBJ…

The Rolex Datejust is widely regarded as the archetype of the classic Swiss watch, having debuted in 1945 as the first self-winding wristwatch to display the date in a window on the dial. Over the decades the collection expanded to include the mid-size 31mm case, a versatile format that sits elegantly on a range of wrists and has earned devoted admirers who seek something between the petite Lady-Datejust and the full 36mm model. Reference 278240MDBJ represents the Datejust Lady 31 at its most extraordinary, combining Rolex's enduring design language with some of the rarest materials available in fine watchmaking.

The 31mm Oyster case of reference 278240MDBJ is constructed in Rolex's proprietary Oystersteel — a 904L stainless steel alloy celebrated for its exceptional corrosion resistance and its ability to accept a mirror polish that rivals precious metal — and is further elevated by 18k white gold crown guards and crown tube. The integration of white gold lends a quietly luxurious contrast to the polished and satin-brushed steel surfaces, signaling this reference's position at the elevated end of the Datejust 31 range.

The dial is the undisputed focal point of this reference: a genuine slice of meteorite, sourced from iron-nickel meteorites that drifted through space for billions of years before being recovered on Earth. When cut and polished, meteorite reveals the Widmanstätten crystalline pattern — a geometric lacework of interlocking lines that formed during slow cooling in the void of space and cannot be replicated by any industrial process. Because every meteorite slab is unique, no two 278240MDBJ dials are identical, conferring each watch with an irreproducible character that deeply appeals to collectors.

Encircling the dial is a custom diamond-set bezel, its entire surface paved with brilliant-cut diamonds that catch and scatter light with every movement of the wrist. The combination of the icy white-gold-and-steel case, the cosmic grey meteorite dial, and the continuous sparkle of the diamond bezel creates a piece of wearable art that transitions effortlessly from daytime elegance to evening occasions. Completing the ensemble is the iconic five-piece link Jubilee bracelet, originally introduced alongside the Datejust in 1945 and still considered one of the most comfortable and refined bracelets in horology. The watch is powered by an automatic movement and carries a water resistance of 100 meters (330 feet), ensuring it is as capable as it is beautiful.
