Rolex Datejust 31 31 mm 278384RBRGDO Steel/White Gold/Diamonds Grey

The Rolex Datejust is one of the most enduring icons in watchmaking history, introduced in 1945 as the first self-winding wristwatch to display the date in a window at 3 o'clock. Over eight decades the design language has remained instantly recognizable while Rolex has continuously refined proportions, materials, and complications. The 31mm case size sits at the intersection of the brand's traditionally feminine and mid-size offerings, delivering the full gravitas of the Datejust in a wrist-friendly, versatile diameter that appeals to a broad range of collectors and everyday wearers alike.

Reference 278384RBRGDO is a statement piece within the Datejust 31 family, pairing the robustness of Oystersteel with the prestige of 18k white gold in a two-tone configuration that Rolex calls Rolesor. The Oyster case measures a precise 31mm in diameter, a size that wears with quiet confidence without overpowering a smaller wrist. Oystersteel, Rolex's proprietary alloy drawn from the 904L steel family, is renowned for its exceptional resistance to corrosion and its ability to take and hold a mirror polish that few other alloys can match.

The dial of this reference is finished in a sophisticated dark grey tone and set with diamonds, giving it a depth and shimmer that shifts dramatically under different lighting conditions. Complementing the dial is the diamond-set bezel, which replaces the traditional fluted or smooth bezel with a continuous band of brilliant-cut stones that frame the dial in a halo of light. Together, the diamond dial and diamond bezel create a layered brilliance that distinguishes this reference from plainer Datejust variants while remaining unmistakably Rolex in its restrained elegance.

Powering the watch is an automatic movement, ensuring the convenience of self-winding mechanics that keep the watch running from the natural motion of the wrist. The Oyster bracelet completes the package with its characteristic three-piece flat link construction, offering both security and comfort. Rolex rates this reference to 100 meters (330 feet) of water resistance, a testament to the integrity of the Oyster case's hermetic seal and a reassuring specification for a watch intended for active daily wear.
