Rolex Lady-Datejust 28 Everose Rolesor Diamond Bezel — Chocolate Roman Dial | Ref. 279381RBR

Reference 279381RBR represents the Lady-Datejust 28 at its most luxuriously appointed: an Everose Rolesor configuration — combining Oystersteel with Rolex's proprietary 18 ct rose-gold alloy — complemented by a bezel set entirely with brilliant-cut diamonds, designated by the RBR suffix. The rich chocolate dial with Roman numeral markers creates a deeply sophisticated chromatic contrast against the warm blush of the Everose gold, while the diamond bezel adds a jewellery-watch dimension that elevates this 28 mm timepiece into the realm of wearable fine art.

Beneath the flawlessly finished Oyster case lies the Calibre 2236, Rolex's flagship ladies' movement introduced with the 279xxx generation. The 2236 incorporates a Syloxi silicon hairspring — an innovation from Rolex's own research and development — conferring exceptional resistance to magnetic fields and thermal fluctuations. It delivers a 55-hour power reserve and earns Superlative Chronometer certification at ±2 seconds daily accuracy, certified by an independent body after casing. The five-position regulation and instantaneous date mechanism with Cyclops magnification complete a technically comprehensive package within a case just 28 mm in diameter.

The chocolate dial is among the most consistently sought-after colour configurations in the Lady-Datejust range, particularly when paired with Everose Rolesor and a diamond bezel. This combination produces a watch of genuine rarity on the secondary market, where clean examples with matching bracelet and original accessories regularly achieve prices well above standard steel references. For the collector who appreciates the intersection of diamond-set craft, exclusive rose alloys and manufacture horology in a single offering, reference 279381RBR is a compelling and rewarding acquisition.
