Rolex Datejust Lady 31 31 mm 278240SDBJ Steel/White Gold/Diamonds Silver Rolex Datejust Lady 31 31 mm 278240SDBJ…

The Rolex Datejust is widely regarded as the watch that defined the modern dress timepiece, and the Lady 31 expression of that lineage—reference 278240SDBJ—demonstrates exactly why the collection has remained desirable for decades. Introduced as a midsize format that sits comfortably between the classic Lady-Datejust 28 and the full-size 36, the 31mm case strikes an ideal balance for wrists that want presence without excess. With Oystersteel paired with 18k white gold accents, this reference blends workaday durability with genuine fine-jewelry credentials.

The case measures 31mm in diameter and is crafted from Rolex's proprietary Oystersteel, an alloy in the 904L family prized for its exceptional corrosion resistance and high polish retention. White gold elements elevate the composition, lending a cool, luminous contrast against the steel that gives the watch a quietly luxurious character. The Oyster case architecture provides robust protection, and the watch is rated to 100 meters (330 feet) of water resistance, meaning it accompanies the wearer through everyday life without worry.

The silver dial is one of the most timeless choices in the Datejust palette—crisp, light-catching, and endlessly legible. It pairs seamlessly with the custom diamond-set bezel, whose stones encircle the case and catch light from every angle. Together, the dial and bezel create a cohesive fine-jewelry sensibility that is entirely in keeping with the Datejust tradition of blending horological function with decorative artistry.

Powering the 278240SDBJ is Rolex's self-winding automatic movement, a technology the brand has refined over generations to deliver consistent, reliable timekeeping. The movement winds itself through the natural motion of the wrist, requiring no battery and minimal intervention from the wearer. This mechanical heart, housed invisibly beneath the elegant exterior, is central to the Datejust's enduring reputation for precision.

The Jubilee bracelet fitted to this reference is a design that Rolex introduced alongside the very first Datejust in 1945, and it remains one of the most recognized bracelets in watchmaking. Its five-piece-link construction imparts a fluid, almost fabric-like drape on the wrist, and the fine alternation of polished and brushed surfaces gives it a jewel-like refinement. The combination of the Jubilee bracelet with the diamond bezel and silver dial creates a cohesive statement that reads as unmistakably Rolex.
