Rolex Lady-Datejust 28 Yellow Gold — 44-Diamond Bezel Champagne Index Dial | Ref. 279138RBR

Reference 279138RBR is the Lady-Datejust 28 in solid 18ct yellow gold, fitted with a 44-diamond bezel and a champagne index dial—a combination that brings every major element of the watch into a warm, cohesive tonal register. The champagne dial, with its index hour markers catching the light alongside the surrounding diamond bezel, creates a layered luminosity that is characteristic of Rolex's most accomplished small-dress-watch configurations. At 28 mm, the case is sized precisely for smaller wrists, providing an elegantly scaled presence that larger references cannot replicate.

Calibre 2236 powers this reference—a movement developed specifically for Lady-Datejust and Pearlmaster references in the 28–31 mm range. It incorporates the Syloxi silicon hairspring for improved magnetic resistance and chronometric stability, and carries full COSC chronometer certification. The solid yellow gold Oyster case and matching Jubilee bracelet are machined and finished to the same standards as Rolex's larger models, with no concession to scale. The diamond bezel setting uses factory-certified gems individually graded and set in-house at Rolex.

For buyers and collectors, the 279138RBR in yellow gold with diamond bezel represents the Lady-Datejust at its most traditional and valuable configuration—no Rolesor compromise, no alternative materials, just solid gold and genuine diamonds throughout. Demand for this configuration is anchored by a clientele that appreciates the watch's dual role as both functional timepiece and fine jewellery, and secondary market performance reflects that sustained interest. As a gifting piece or personal acquisition, few watches deliver Rolex's mechanical credibility alongside this level of decorative execution.
