Rolex Lady-Datejust 28 White Rolesor — 44 Diamond Bezel Dark Grey Index Dial | Ref. 279384RBR

Reference 279384RBR brings the Lady-Datejust 28 to full gem-set expression — the 'RBR' suffix designating a bezel set with 44 brilliant-cut diamonds in an alternating ruby-and-diamond configuration that encircles the case perimeter with lapidary precision. The White Rolesor construction, combining Oystersteel and 18ct white gold, provides a neutral metal backdrop against which the dark grey index dial offers cool, understated depth. The contrast between the animated bezel and the measured simplicity of the dial is a calibrated tension central to Rolex's high jewellery philosophy.

At 28mm, this is Rolex's current Lady-Datejust standard, housing Calibre 2236 — a dedicated ladies' manufacture movement incorporating the Syloxi silicon hairspring, Parachrom technology, and an oscillating mass optimised for the smaller movement diameter. The dark grey dial with applied index markers is free of additional gem-setting, allowing the 44-stone diamond-ruby bezel to command focus. The Jubilee bracelet in White Rolesor echoes the case material, its five-link construction providing the supple wrist articulation that remains the Lady-Datejust's hallmark.

The 279384RBR is positioned for the collector who values the Lady-Datejust as a jewellery object as much as a timepiece. The alternating diamond-ruby bezel is a distinctive and relatively uncommon configuration, and examples in strong condition with full documentation attract a premium in the secondary market. Its 28mm footprint and gem-set architecture make it an ideal candidate for pairing with high jewellery or as a formal standalone statement watch.
