Rolex Lady-Datejust 31 31 mm 278273WRO Steel/Yellow Gold White

The Rolex Lady-Datejust 31 is one of watchmaking's most enduring icons—a timepiece that has defined elegance on the wrist since Rolex introduced the Datejust family in 1945, making it the first self-winding wristwatch to display the date in a window at 3 o'clock. The Lady-Datejust line distills that storied heritage into a refined 31 mm case proportion that flatters a wide range of wrists without sacrificing any of the presence and authority the Datejust name commands. Reference 278273WRO represents a current-generation expression of this legacy, available brand new and complete at Bizak & Co.

The 31 mm Oyster case of the 278273WRO is constructed in Rolex's proprietary Oystersteel—a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish—accented throughout with 18 ct yellow gold. This two-tone combination, often called Rolesor in Rolex parlance, is among the most recognisable and requested configurations in the entire Datejust catalogue, offering the sporty resilience of steel alongside the warmth and prestige of solid gold. The Oyster case is hermetically sealed to 100 metres (330 feet) water resistance, making it suitable for everyday wear including swimming and light water activities.

At the heart of the dial design is a clean white surface that reads with exceptional legibility and a timeless, uncluttered quality. White dials have long been among the most versatile choices in the Lady-Datejust family—equally at home against a business suit, an evening gown, or casual weekend attire. The iconic date aperture at 3 o'clock remains the watch's defining complication, magnified by Rolex's patented Cyclops lens for instant, effortless reading.

Crowing the case is a yellow gold fluted bezel, one of the most historically significant design elements in the Datejust's visual identity. The fluted bezel originated as a technical feature—its grooves originally served to screw the bezel onto the case, ensuring water resistance—before evolving into a pure aesthetic hallmark synonymous with Rolex elegance. Paired with the yellow gold Rolesor construction of reference 278273WRO, the fluted bezel creates a coherent, luminous two-tone statement. The watch is presented on Rolex's Oyster bracelet, a three-link design that is both supremely comfortable for daily wear and architecturally harmonious with the Oyster case.

Powering the Lady-Datejust 31 is an automatic movement, reflecting Rolex's decades of expertise in precision self-winding mechanics. The rotor winds the mainspring through the natural motion of the wearer's wrist, ensuring the watch remains ready without manual intervention. Rolex movements are assembled, tested, and certified to meet the brand's exacting in-house standards, delivering the reliability that generations of owners have come to depend upon in a daily wear timepiece.
