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

Reference 278285RBR belongs to the gem-set pinnacle of the Datejust 31 programme, housing the watch entirely within 18 ct Everose gold — Rolex's proprietary rose-gold alloy formulated with platinum to resist the colour fade that afflicts conventional rose golds over time. The bezel is pavé-set with 46 brilliant-cut diamonds selected and matched for consistent colour and clarity, their collective radiance forming a continuous ring of light around the dial. The case and caseback are secured by the screw-down Twinlock crown, preserving waterproofness to 100 metres.

The silver dial is set entirely with diamond hour markers, each stone individually claw-set against the polished silver lacquer field. The interaction between the cool silver ground and the warm Everose gold case creates the same carefully managed chromatic tension that defines Rolex's most successful gem-set references. A cyclops lens over the sapphire crystal amplifies the date aperture at three o'clock, and the scratch-resistant coating ensures the crystal maintains its optical clarity across years of wear.

Calibre 2236 powers this reference, the same manufacture movement used across the current Datejust 31 and Lady-Datejust 28 ranges. Its silicon Syloxi hairspring renders the oscillator impervious to magnetic disturbance and immune to lubricant degradation, while a redesigned barrel and gear train deliver approximately 55 hours of power reserve — exceptional for a movement of this size class. The Everose gold Oyster bracelet, with its flat three-piece links, is fitted with a concealed folding Crownclasp that completes the seamless precious-metal architecture of the watch.
