Rolex Datejust 36 36 mm 126284RBRBKSJ Steel/White Gold/Diamonds Black

The Rolex Datejust is the definitive dress watch, a model that has defined the genre since its introduction in 1945 as the first self-winding wristwatch to display the date in a window at 3 o'clock. Across its many decades of production the Datejust has evolved through successive case generations while maintaining an unbroken commitment to elegance, precision, and versatility. The current 36mm platform, represented by the reference 126284RBRBKSJ, sits at the heart of the modern Datejust family and carries forward every refinement Rolex has introduced in the contemporary era.

The 126284RBRBKSJ is built on a 36mm Oyster case in Oystersteel—Rolex's proprietary 904L stainless steel alloy chosen for its exceptional corrosion resistance and lustrous finish—paired with 18k white gold crown guards, crown, and bezel setting. The bezel itself is set with brilliant-cut diamonds, catching light from every angle and elevating what might otherwise be a sport-adjacent silhouette into thoroughly haute-horlogerie territory. Water resistance is rated to 100 meters (330 feet), a specification that speaks to the robustness of the Oyster case construction.

The dial is finished in a deep, immaculate black, providing a dramatic backdrop that allows the diamond bezel to command attention while keeping the hour markers and hands legible. The interplay of the dark dial against the scintillating white gold and diamond surround creates a versatile aesthetic that transitions seamlessly from boardroom to evening event. This is a Datejust that wears its luxury without restraint.

Powering the watch is a Rolex automatic movement, the product of decades of in-house manufacture. Rolex automatic calibers are renowned for their COSC-certified chronometric precision, the Perpetual rotor that winds efficiently from the wrist's natural motion, and long-term reliability that has been proven across millions of examples in daily use worldwide. The movement's robustness is well-documented across the entire modern Datejust lineup.

The watch is presented on Rolex's celebrated five-piece link Jubilee bracelet, a design introduced alongside the original Datejust in 1945. The Jubilee is synonymous with refined elegance, its supple articulation and Oystersteel and white gold construction perfectly matching the two-tone aesthetic of this reference. It fastens via the Oysterlock safety clasp with Easylink comfort extension, providing a secure and precise fit on the wrist.
