Rolex Datejust 31 Everose Rolesor — Mother-of-Pearl Diamond Dial | Ref. 278381RBR

Ref. 278381RBR occupies the apex of the current Datejust 31 range, combining Everose Rolesor construction with one of the most opulent dial configurations in the mid-size catalogue. Everose Rolesor pairs an Oystersteel case body with 18ct Everose gold bezel setting, crown, and bracelet centre links — the warm rose tone providing a compelling contrast against the steel flanks. The 46-diamond bezel, set with brilliant-cut stones in a full pavé arrangement, frames a mother-of-pearl dial further adorned with diamond hour indices, delivering exceptional jewellery density within a eminently wearable 31mm form.

The movement is Calibre 2236, Rolex's in-house manufacture calibre for the 31mm and 28mm families. The Syloxi silicon hairspring resists both magnetism and temperature fluctuation more effectively than conventional alloy alternatives, contributing to the movement's Superlative Chronometer rating of +/-2 seconds per day. A 55-hour power reserve ensures the watch runs through a full weekend without winding. The Jubilee bracelet in Everose Rolesor configuration — steel outer links, Everose gold centres — sits comfortably on the wrist and pairs elegantly with the overall finish.

Everose Rolesor diamond-bezel Datejust 31 examples represent one of the strongest value propositions in the Rolex jewellery-watch segment. The Rolesor construction keeps the price meaningfully below a full gold equivalent while retaining the warm rose aesthetic, and the mother-of-pearl diamond dial ensures visual impact well beyond the watch's entry price. Collectors focused on jewellery watches with genuine horological pedigree consistently identify this reference as a benchmark purchase.
