The Rolex Lady-Datejust 28 Ref. 279138 in the SDJ configuration represents a spectacular fusion of classic Rolex design and high-jewelry finishing within the current 28 mm generation. This magnificent timepiece is crafted entirely from traditional and luxurious 18K Yellow Gold, providing a rich, warm, and radiant presence on the wrist. Its status is elevated by the dazzling Diamond-Set Bezel, which features a precise arrangement of brilliant-cut factory diamonds, creating an intense, continuous halo of sparkle that exquisitely frames the dial.
The absolute focal point of this watch is the timeless Silver Sunray Finish Diamond Dial . This luminous, bright silver hue serves as a pristine, reflective canvas that perfectly contrasts with the warmth of the surrounding yellow gold. The dial is adorned with 10 brilliant-cut diamond hour markers, each meticulously mounted in 18K Yellow Gold settings. This combination of the bright silver backdrop and the superb diamond indices ensures exceptional legibility while delivering a captivating aesthetic that is both traditional and overwhelmingly luxurious.
