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

The Rolex Datejust is one of the most storied and instantly recognizable watch families in horology, and the 31mm case size occupies a sweet spot that suits a broad range of wrists while retaining every architectural detail of the full-size models. First introduced in 1945 as the first self-winding wristwatch to display the date in a window at 3 o'clock, the Datejust has evolved continuously while keeping the core design language unchanged. Reference 278274BLURJ sits at the contemporary apex of that lineage, combining modern materials mastery with the timeless Datejust silhouette.

The case and bracelet of the 278274BLURJ are rendered in a harmonious pairing of Oystersteel—Rolex's proprietary 904L stainless steel prized for its exceptional corrosion resistance and mirror-polish retention—and 18k white gold. The 18k white gold fluted bezel is perhaps the Datejust's most iconic design signature, its precise geometric serrations catching light from every angle and lending the watch an unmistakably formal character. At 31mm in diameter, the Oyster case remains a robust, waterproof shell rated to 100 meters (330 feet), protected by a screw-down Triplock crown.

The bright blue Roman numeral dial is the visual centerpiece of this reference. The rich, saturated blue creates a striking backdrop against which the white gold applied Roman hour markers read with exceptional legibility. The date aperture at 3 o'clock is magnified by Rolex's patented Cyclops lens, a detail that elevates quick time-reading to an art form. The overall effect is simultaneously bold and refined—a dial that announces itself without shouting.

Power comes from a Rolex-manufactured automatic movement, the same category of in-house mechanical engineering that defines the brand's reputation for reliability and precision. The movement is protected within the hermetically sealed Oyster case, ensuring stable performance across a wide range of conditions. For a watch intended to be worn daily, this combination of craftsmanship and engineering provides the confidence that Rolex owners have come to expect over decades.

The five-piece-link Jubilee bracelet, originally introduced alongside the very first Datejust in 1945, completes the package. Its elegant articulation and comfortable drape on the wrist are legendary among enthusiasts, and in Oystersteel it maintains the same lustrous finish as the case. The Jubilee clasp provides a secure, adjustable fit and contributes to the overall sense of understated luxury that defines this reference.
