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

Reference 279138RBR represents the Lady-Datejust 28 at its most opulent — a fully jewelled configuration in 18 ct yellow gold with a factory-set 44-diamond bezel and a champagne dial paved with diamonds. The Lady-Datejust 28 is Rolex's principal dress watch for women, combining the Datejust's iconic date complication with proportions and decoration calibrated for elegance. This reference is built entirely by Rolex in-house, with every diamond selected and set at the Geneva manufacture to exacting grading standards.

Calibrated with Calibre 2236, Rolex's manufacture movement developed specifically for the brand's smaller-cased women's watches, the 28 mm Oyster case houses an oscillator featuring a Syloxi silicon hairspring — a material that is both antimagnetic and resistant to thermal variation. The 44-stone RBR diamond bezel is set in a bright-cut style that maximises brilliance across the full circumference of the case, while the champagne diamond dial presents baguette or brilliant-cut hour markers depending on the specific dial variant. The bracelet material is 18 ct yellow gold.

In the secondary market, diamond-set Lady-Datejust references in full yellow gold command consistent interest from buyers who prize jewellery-grade Rolex pieces as both wearable objects and stores of value. The RBR designation confirms the bezel is set with genuine diamonds, and the champagne diamond dial elevates this piece beyond a standard dress watch into collector territory. It is an ideal acquisition for those who approach horology through the lens of jewellery and enduring luxury.
