Rolex Lady-Datejust 28 Everose Gold — Chocolate Index Dial, 44-Diamond Bezel | Ref. 279135RBR

Rolex's proprietary 18 ct Everose gold alloy — developed in-house at the brand's foundry and formulated with a small percentage of platinum to resist the fading that can afflict conventional rose gold — lends Reference 279135RBR a warmth that is both distinctive and enduring. The 28 mm Oyster case is crowned by a bezel pavé-set with 44 brilliant-cut diamonds, their total radiance framing the dial in an unbroken arc of scintillation.

The chocolate dial is one of the most coveted dial colours in the Datejust catalogue, its deep brown ground possessing a richness that shifts subtly under different light sources. Chromalight-filled index hour markers provide dependable legibility in low light, their long-lasting blue luminescence a practical counterpoint to the dial's luxurious visual character. The President bracelet in matching Everose gold — reserved exclusively for Lady-Datejust and Day-Date references in precious metal — provides a fluid drape that flatters the wrist.

Calibre 2236 powers this reference, a self-winding movement entirely conceived and produced by Rolex and specifically engineered for the Lady-Datejust family. The Syloxi hairspring — machined from silicon by Rolex's own micromechanical facility — offers a ten-fold improvement in precision over conventional hairsprings in the presence of magnetic fields. A power reserve of approximately 55 hours and water resistance to 100 metres confirm that luxury and technical merit are inseparable in this reference.
