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

The Rolex Datejust is one of the most storied timepieces in watchmaking history, having defined the category of the classic dress watch since its introduction in 1945. As the first self-winding wristwatch to display the date in a window on the dial, the Datejust set a standard for elegance and mechanical refinement that has never wavered. The 31mm case size positions this reference squarely as a versatile choice suited to a wide range of wrists, offering full Rolex presence without excess.

Reference 278344RBRGRVIDO represents one of the most luxurious configurations in the current Datejust 31 collection. The case and bracelet are crafted in Rolex's proprietary Oystersteel—an alloy from the 904L steel family prized for its exceptional corrosion resistance and high-polish luster—while the bezel, crown, and key structural elements draw on 18k white gold for a cool, precious contrast. Together these materials create the signature Rolesor aesthetic that has been a Datejust hallmark for decades.

The grey dial is set with Roman numeral hour markers and finished to Rolex's exacting standards, providing a contemporary yet timeless face that pairs effortlessly with both casual and formal attire. The diamond-set white gold domed bezel adds a layer of brilliance that catches the light from every angle, elevating this reference from a classic dress watch into a piece of fine jewelry for the wrist. The combination of grey and white-gold diamonds gives the watch a cool, sophisticated palette that stands apart from warmer gold or champagne alternatives.

Powering the watch is a Rolex automatic movement, housed within the iconic Oyster case that has been the foundation of Rolex's waterproof watchmaking since 1926. The screw-down Oyster crown ensures the case is sealed to 100 meters (330 feet) of water resistance, making this elegantly jeweled timepiece far more robust than its appearance might suggest. The Oyster bracelet—flat three-piece links that are immediately recognizable as pure Rolex—provides secure wear and a fluid drape on the wrist that improves with time.

For collectors and first-time Rolex buyers alike, the Datejust 31 in this diamond and grey configuration represents a compelling entry into Rolex's most enduring line. Its 31mm diameter sits at the crossroads of the brand's mid-size and ladies' offerings, making it a genuine choice for any wrist size that prefers a refined, jewelry-forward profile.
