Rolex Datejust 31 31 mm 278344RBRSSJ Steel/White Gold/Diamonds Silver

The Rolex Datejust is one of the most enduring watch designs in horological history, introduced in 1945 as the first self-winding wristwatch to display the date in a window on the dial. Over nearly eight decades the line has evolved in size, material, and decoration while always retaining the clean, date-forward aesthetic that made it iconic. The Datejust 31 occupies a beloved mid-size sweet spot between the ladies' 28mm and the full-size 36mm, offering a versatile 31mm case that sits beautifully on a broad range of wrists.

Reference 278344RBRSSJ represents the Datejust 31 at its most refined. The case and bracelet combine Rolex's proprietary Oystersteel—a 904L stainless steel alloy prized for its exceptional corrosion resistance and high polish—with 18k white gold on the bezel, crown, and key case elements. This two-material construction gives the watch a luminous, jewelry-forward character that photographs in silver tones while catching light in ways a mono-material case simply cannot match.

The bezel is the defining design statement of this reference: a domed profile set entirely with diamonds in 18k white gold, a hallmark of Rolex's highest-decoration Datejust variants. Paired with a silver dial dressed with index hour markers, the overall palette is cool, bright, and cohesive. The dial reads with the clarity Rolex demands while the surrounding diamond bezel ensures this watch announces itself as something special.

Powering the 278344RBRSSJ is a Rolex automatic movement, the product of the brand's fully in-house manufacturing philosophy that encompasses research, development, and production of every key component. The Oyster case provides the hermetic protection that has long defined Rolex reliability, and the watch is rated to 100 meters (330 feet) of water resistance—meaningful everyday assurance for a piece worn as both a dress watch and a daily companion.

The Jubilee bracelet completes the picture. First introduced alongside the original 1945 Datejust, the five-piece link Jubilee is considered one of the most comfortable and elegant bracelets Rolex makes, sitting softly on the wrist and complementing the polished-and-brushed case finishing. For collectors seeking a Rolex Datejust 31 with diamond bezel and Jubilee bracelet, the 278344RBRSSJ is the definitive choice.
