Rolex Datejust 31 31 mm 278274BLURO Steel/White Gold Blue Rolex Datejust 31 31 mm 278274BLURO Steel/White…

The Rolex Datejust is one of the most enduring icons in watchmaking—introduced in 1945 as the first self-winding waterproof wristwatch to display the date through a magnified window on the dial, it has defined the modern dress watch for nearly eight decades. The 31mm case size occupies the sweet spot between the original 36mm and the smaller Lady-Datejust, making it a genuinely versatile choice for a wide range of wrists and styles. Reference 278274BLURO represents the current generation of this storied line, blending time-tested design principles with Rolex's contemporary manufacturing standards.

The case and bracelet are built in Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional corrosion resistance and deep, lasting polish. The crown elements—bezel and certain bracelet components—are rendered in 18k white gold, creating the two-tone contrast that has been a Datejust signature since the 1970s. The 18k white gold fluted bezel is one of Rolex's most recognizable design motifs: originally conceived to act as a functional gasket, it evolved into a hallmark of the Datejust's identity, its precisely machined ridges catching light with every movement of the wrist.

The bright blue dial of the 278274BLURO commands immediate attention. Roman numerals lend a classical, almost architectural quality to the chapter ring, contrasting beautifully against the vivid blue surface. The Cyclops lens over the date window magnifies the date 2.5 times for instant legibility—a Rolex patent that remains one of the most practical complications in everyday watchmaking. Together, dial, indices, and lens create a face that is simultaneously bold and refined.

Powering the watch is a Rolex automatic movement, ensuring reliable self-winding operation through the motion of the wearer's wrist. The Oyster case provides water resistance to 100 meters (330 feet), making this Datejust a credible companion for swimming and everyday exposure to water—well beyond the demands of typical dress-watch wear. The Oyster bracelet, with its three-piece link construction and integrated folding Crownclasp, delivers the secure, comfortable fit that has made it the benchmark for integrated sports-dress bracelets across the industry.
