Rolex Datejust 28 Everose Gold — 44 Diamond Bezel White Roman Dial | Ref. 279135RBR

Reference 279135RBR occupies the apex of the Lady-Datejust 28 hierarchy — a configuration in which every element of the watch has been elevated to the highest available specification. The case, bezel, crown, and President bracelet are all fabricated in 18 ct Everose gold, Rolex's proprietary rose-gold alloy whose formula includes a small quantity of platinum to stabilise the copper-gold-silver matrix and ensure that the warm blush tone resists the colour fading that afflicts conventional rose gold over time. The bezel is set with 44 brilliant-cut diamonds — denoted by the RBR suffix in the reference designation — whose individual selection and channel setting by Rolex's Geneva-based gem artisans results in a circuit of continuous brilliance around the dial's perimeter.

The white lacquered dial carries Roman numeral hour markers in polished Everose gold, their classical proportions harmonising with the warmth of the case and bracelet in a tonal composition of exceptional coherence. Roman numerals have appeared on the Datejust since the earliest years of the collection's history, their association with European horology lending the dial an intellectual authority that index or diamond markers cannot replicate. The Cyclops lens magnifies the date at 3 o'clock to 2.5 times its actual size, preserving the Datejust's functional identity within a watch whose jewellery credentials are equally pronounced. The President bracelet — a construction exclusive to gold Day-Date and Lady-Datejust references — provides a prestige-tier wrist experience whose semi-circular three-link architecture and concealed clasp are among the most refined bracelet constructions in Rolex's portfolio.

Inside the 28 mm Oyster case, Calibre 2236 operates with Syloxi silicon hairspring technology and a 55-hour power reserve, the movement's Superlative Chronometer certification attesting to a positional accuracy of ±2 seconds per day. The combination of diamond bezel, Everose gold throughout, white Roman dial, and President bracelet has historically commanded strong retention in the secondary market, a function of the reference's completeness as a jewellery-watch concept and the enduring desirability of Rolex's precious-metal Lady-Datejust variants among collectors who recognise the brand's unique position at the intersection of mechanical horology and haute joaillerie.
