Rolex Datejust 31 Yellow Gold — Diamond Bezel Mother-of-Pearl Diamond Dial | Ref. 278288RBR

Presented entirely in 18-carat yellow gold, the Datejust 31 Ref. 278288RBR occupies the apex of the collection's jewellery expression, synthesising precious metal, brilliant diamonds, and the natural beauty of mother-of-pearl into a unified composition of rare coherence. The 31 mm Oyster case in yellow gold is fitted with a bezel set with 46 brilliant-cut diamonds — a stone count that exceeds many dedicated jewellery bezels — creating a ring of gemstone brilliance that frames the dial with unambiguous opulence.

The mother-of-pearl dial is among the most coveted in the Datejust range, its iridescent surface cut from natural shell material that exhibits unique optical properties under varying light conditions. The play of colour — shifting through creams, silvers, and subtle pinks — cannot be replicated by any manufactured surface, and each dial is therefore unique. Ten diamond hour markers replace conventional indices, their individual brilliance scattered across the dial surface to create a constellation effect that animates the watch with every movement. The Cyclops lens at 3 o'clock brings the date into sharp focus against this jewelled backdrop. Calibre 2236, Rolex's self-winding manufacture movement with silicon Syloxi hairspring, delivers approximately 55 hours of power reserve.

The integrated 18-carat yellow gold Oyster bracelet — flat three-piece links with polished and brushed surfaces — completes the all-gold presentation, its substantial weight and warm lustre providing a tactile as well as visual statement. The concealed folding Crownclasp secures the bracelet with the reliability demanded of a Rolex. Waterproof to 100 metres, the 278288RBR is a definitive Datejust for the collector who seeks precious metal watchmaking at its most fully realised.
