Rolex Datejust 31 31 mm 278274BLKRO Steel/White Gold Black

The Rolex Datejust is one of the most recognized and enduring watch designs in horological history, introduced in 1945 as the first wristwatch to display the date automatically in a window on the dial. Across nearly eight decades of continuous production, the Datejust has evolved in materials, sizing, and decoration while preserving the core design language that made it legendary. The 31 mm variant occupies a sweet spot in the Datejust family, offering a refined mid-size case that suits a wide range of wrist sizes without sacrificing any of the presence or prestige associated with the line.

Reference 278274BLKRO represents a particularly compelling combination of materials and finishing. The 31 mm case is constructed from Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and lustrous polish — complemented by 18k white gold accents that elevate the piece into luxury territory. The white gold fluted bezel is one of Rolex's most storied design signatures, its serrated profile reflecting light dynamically and lending the watch an immediately recognizable silhouette.

The black dial anchors the aesthetic with depth and sophistication, providing a high-contrast backdrop that allows the dial furniture and hands to read with remarkable clarity. Black dials have long been favored for their versatility, transitioning effortlessly between casual and formal contexts. The combination of a black dial with white gold and steel casing gives this reference a bold, modern sensibility that distinguishes it within the broader Datejust family.

The watch is worn on Rolex's iconic Oyster bracelet, a three-piece link design that has remained essentially unchanged in concept since 1931. The Oyster bracelet is widely regarded as one of the most comfortable and durable metal bracelets in watchmaking, and in this configuration it is rendered in matching Oystersteel with white gold center links, reinforcing the two-tone luxury aesthetic. Automatic movement powers the watch, ensuring effortless daily timekeeping without the need for manual winding. Water resistance to 100 meters (330 feet) is provided by the Oyster case construction, making this Datejust 31 suitable for everyday wear including exposure to water.
