Rolex Datejust 31 31 mm 278344RBRGDJ Steel/White Gold/Diamonds Grey

The Rolex Datejust 31 reference 278344RBRGDJ stands as one of the most refined expressions of a watch family that has defined horological elegance since 1945. The Datejust was the first self-winding waterproof wristwatch to display the date in a window on the dial, and it remains Rolex's most enduring and recognizable collection. The 31mm case size occupies a beautifully versatile middle ground, fitting equally well on a range of wrists and serving equally as a statement dress piece or a refined everyday companion.

The case and bracelet of the 278344RBRGDJ are constructed in Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and brilliant polish — combined with 18k white gold elements that elevate the watch into true luxury territory. The white gold domed bezel is set with diamonds, each selected for cut, clarity, and color, framing the dial in a continuous arc of brilliance that catches the light from every angle.

The grey dial is a masterclass in understated sophistication. Its deep, cool tone provides a neutral canvas that allows the diamond hour markers to shimmer without competing with the bezel, creating a cohesive and harmonious aesthetic. Grey dials have grown significantly in collector popularity for their ability to read as both formal and casual depending on context, and this particular shade pairs beautifully with the cool tones of the white gold and steel case.

Powering the watch is a Rolex automatic movement, engineered and manufactured entirely in-house at Rolex's facilities in Geneva and Biel. Rolex automatic movements are certified Swiss chronometers, held to accuracy standards that far exceed the Swiss official standard, and they are built for decades of reliable service with regular servicing. The Oyster case provides water resistance to 100 meters (330 feet), ensuring that this watch is as practical as it is beautiful.

The Jubilee bracelet, introduced by Rolex alongside the original Datejust in 1945, completes the reference with its characteristic five-piece link design that drapes elegantly around the wrist. Its fine articulation provides both comfort and visual refinement, making it the natural choice for a diamond-set Datejust.
