Rolex Datejust 31 Everose Gold — Diamond Bezel Chocolate Diamond Dial | Ref. 278285RBR

Introduced at Baselworld 2019, Reference 278285RBR represents one of the most striking colour combinations in the contemporary Datejust 31 collection. The 31mm case in 18K Everose gold is crowned by a bezel set with 46 brilliant-cut diamonds, whose white fire plays against the warm rose-gold surround in a calculated chromatic tension. The chocolate dial — a rich, deeply saturated brown lacquer unique to Rolex's colour vocabulary — is set with ten diamond hour markers, each stone selected for consistent cut and colour against the dark background. The result is a dial of genuine warmth and depth, far removed from the pale pastels more conventionally associated with jewellery watches.

Calibre 2236 drives the watch — Rolex's purpose-built manufacture movement for the 31mm Datejust family, featuring the proprietary Syloxi silicon hairspring, stop-seconds for precise time-setting, instantaneous date display with rapid correction, and approximately 55 hours of power reserve. The screw-down Twinlock crown with its double waterproofness system ensures protection to 100 metres, a technical specification that remains relevant even when the watch is worn as pure jewellery.

The President bracelet in 18K Everose gold encloses the composition with its signature semi-circular three-piece links and concealed Crownclasp, maintaining the monochromatic rose-gold unity from lug to clasp. The 'RBR' suffix in the reference number designates the diamond-set bezel configuration, confirming this as factory-original stone-setting from Rolex's Geneva workshops. For collectors focused on the post-2019 Datejust 31, Reference 278285RBR in the chocolate/diamond combination is among the most coveted configurations — warm, bold, and technically immaculate.
