Rolex Datejust 31 White Rolesor Diamond Bezel — Black Roman Dial Jubilee | Ref. 278384RBR

Contrasts of material and tone define the Datejust 31 Ref. 278384RBR, where the cool luminosity of a diamond-set bezel in White Rolesor — 18 ct white gold on an Oystersteel case — meets a black Roman dial for maximum visual impact. The RBR designation confirms the fully set diamond bezel, whose brilliant-cut stones encircle the 31 mm case in a continuous band of light. Against this brightness, the black dial creates a dark, highly legible backdrop on which the Roman numeral hour markers read with confident clarity, embodying the Datejust's dual identity as both precision timepiece and jewellery object.

The Calibre 2236 self-winding movement operates at the core of this reference, its Syloxi silicon hairspring providing enhanced isochronism and resistance to magnetic interference. Certified as a Superlative Chronometer to -2/+2 seconds per day after casing, the 2236 brings the technical rigour of Rolex's manufacture to a watch that could easily be mistaken for pure jewellery. The Jubilee bracelet — Rolex's most formally elegant bracelet option — provides a five-link construction in White Rolesor that drapes the wrist with exceptional suppleness.

The 278384RBR is one of the most striking entries in the current Datejust 31 matrix, and the black Roman dial configuration is among the more dramatic options available within this size. It commands attention without ostentation, its drama arising from the fundamental tension between the diamond bezel's brilliance and the dial's depth — a tension that Rolex has resolved with characteristic mastery.
