Rolex Datejust 31mm Dark Mother of Pearl 10 Diamond Rolesor Jubilee 278273

Overview 

The 278273 is the Yellow Rolesor variant of the Datejust 31 — Oystersteel case with 18-carat yellow gold bezel, bracelet centre links, and diamond settings. The dial is dark Mother of Pearl, a material that shifts through peacock blue, charcoal, and violet with the light angle; set against yellow gold, the cool iridescence of the dial reads against a warm frame rather than a tonal one. This reverses the logic of the White Rolesor configurations — where white gold and grey dials maintain cool coherence, yellow gold and dark MOP work through contrast.

The case is 31mm Oystersteel with a fluted 18-carat yellow gold bezel. The dark Mother of Pearl dial is sourced from pearl oyster shell; the iridescence is structural, produced by the layered nacre composition rather than any surface treatment, which is why the colour shifts with the viewing angle. No two MOP dials are identical — natural variation in the nacre's layering means each piece has a distinct character. Ten brilliant-cut diamonds are set in yellow gold mountings across the hour positions. The Jubilee bracelet is the five-link construction with yellow gold centre links extending the warm metal detail into the bracelet. Cyclops lens at 3 o'clock; date complication.

The Calibre 2236 — Rolex's movement for the 31mm Datejust — runs a Syloxi silicon hairspring and delivers a 55-hour power reserve. Certified Superlative Chronometer to ±2 seconds per day. Water resistance is 100 metres.

Within the Datejust 31 range, the 278273 occupies a distinct price tier at RM82,000 — above the White Rolesor diamond variants on the basis of both the yellow gold construction and the MOP dial. Mother of Pearl commands a premium over standard lacquered dials because the material is finite, non-reproducible in the same colour pattern, and more demanding to work with during diamond setting. Dark MOP specifically attracts buyers who want the material's full iridescent range without the lightness of white or pink MOP alternatives. Brand new, unworn, complete with box and papers dated May 2026, at RM82,000.
