Rolex Lady-Datejust 28 28 mm 279138RBRSRJ Yellow Gold/Diamonds Silver Rolex Lady-Datejust 28 28 mm 279138RBRSRJ Yellow…

The Rolex Lady-Datejust 28 ref. 279138RBRSRJ is one of the most refined expressions of the Lady-Datejust lineage — a collection that traces its origins to 1957, when Rolex introduced the first purpose-built ladies' Datejust as a scaled counterpart to the iconic Datejust introduced a decade earlier. Over the intervening decades, the Lady-Datejust has evolved in case size and dial options while preserving the model's core identity: a supremely elegant, mechanically serious watch built entirely in-house at Rolex's Geneva manufacture.

At 28mm, the current Lady-Datejust sits at the ideal diameter for a refined ladies' dress watch — large enough to wear with confidence, refined enough to disappear beneath a cuff or complement the most delicate bracelet. The case and Jubilee bracelet of the 279138RBRSRJ are crafted in 18k yellow gold, a material Rolex has mastered through its own proprietary Everose and yellow gold alloys, ensuring color consistency and resistance to fading over decades of daily wear. The five-link Jubilee bracelet, introduced alongside the original Datejust in 1945, remains one of the most recognizable and comfortable bracelets in watchmaking.

The dial of this reference is finished in silver with Roman numeral hour markers — a classical configuration that places the 279138RBRSRJ squarely in the tradition of haute horlogerie dress watches. Roman numerals lend the dial a timeless, almost architectural quality, providing strong legibility while reinforcing the watch's formal character. The signature Rolex cyclops lens over the date window at three o'clock magnifies the date 2.5 times, a practical detail that has defined every Datejust since 1953.

Framing the dial is a diamond-set bezel, which replaces the fluted or smooth bezel options found on other Lady-Datejust references. The individually set brilliant-cut diamonds catch light from every angle, elevating this reference into genuine jewelry-watch territory without sacrificing the mechanical integrity that defines every Rolex. Powering the watch is Rolex's proprietary automatic movement, delivering the day-to-day reliability and precision that Rolex owners expect from a COSC-certified or better chronometer-grade calibre. Water resistance is rated to 100 meters (330 feet), a practical specification that ensures the watch is suitable for daily life well beyond the demands of a dress watch.

For collectors and buyers seeking a Lady-Datejust 28 for sale, the 279138RBRSRJ in yellow gold with a diamond bezel and silver Roman dial represents a particularly desirable configuration — one that holds its appeal across seasons and styling contexts, from boardroom to black tie.
