Rolex Datejust 31 White Rolesor — Domed 24-Diamond Bezel Pink Roman Dial | Ref. 278344RBR

The 278344RBR is a current-generation Datejust 31 that combines White Rolesor construction with a domed bezel set with 24 brilliant-cut diamonds and a pink dial displaying Roman numerals. The domed diamond bezel is a softer, more rounded form than the channel-set flat bezels found on other diamond Datejust variants, and its three-dimensional profile casts the stones at varied angles to maximise light return. White Rolesor — 18-carat white gold bezel and crown set against an Oystersteel case — provides the cool, silver-toned framework that allows the pink dial to register as the primary colour accent.

Calibre 2236 drives the 278344RBR, the same movement that underpins the broader 28mm and 31mm Datejust family in current production. Its Syloxi silicon hairspring and COSC chronometer certification deliver the kind of regulated accuracy and magnetic resistance that modern collectors have come to expect from any new-production Rolex, regardless of its decorative positioning. The pink Roman numeral dial pairs traditional typography with a contemporary colour choice, and the applied lacquer finish gives the ground a depth and lustre that printed dials cannot replicate.

This reference is positioned for buyers who want a 31mm Datejust with genuine jewellery credentials — the 24-diamond domed bezel is a feature of the higher-end Datejust 31 configurations, not a trim-level specification. Roman numerals on a pink ground are a relatively unusual combination within the range, which lends this configuration collectability beyond its raw material content. For pre-owned buyers, the domed bezel demands close inspection: the dome profile makes individual stones slightly more exposed to lateral impact than a flat-set configuration, and any evidence of missing or damaged diamonds should be factored into pricing.
