Rolex Datejust 31 Everose Gold — Diamond Bezel, Rhodium Index Dial | Ref. 278285RBR

Reference 278285RBR represents the Datejust 31 at its most sumptuous, combining the warm sophistication of 18-carat Everose gold with the cool drama of a dark rhodium dial. The 31 mm Oyster case — wrought entirely in Rolex's proprietary Everose alloy, which retains its blush tone indefinitely due to a precise platinum additive — is encircled by a bezel pave-set with 46 brilliant-cut diamonds, selected and mounted by Rolex's in-house gem-setting atelier to exacting standards of uniformity. The Twinlock screw-down crown ensures water resistance to 100 metres despite the dial's jewelled opulence.

The dark rhodium dial presents a sophisticated grey-silver surface that stands in studied contrast to the warm Everose gold case, a chromatic tension that lends this reference an evening-dress formality rare in a 31 mm timepiece. Applied index hour markers in polished Everose gold occupy each hour position, their slender profiles adding a graphic precision to the dial architecture. The Cyclops lens mounted on the sapphire crystal doubles the legibility of the date at the 3 o'clock position, a practical Rolex hallmark present since the 1950s.

The Calibre 2236 — Rolex's manufacture movement for the mid-sized Datejust — beats within at 28,800 vph, incorporating the Syloxi silicon hairspring that renders the oscillator virtually impervious to magnetic interference while delivering enhanced amplitude stability. Power reserve stands at approximately 55 hours. The watch is presented on an 18-carat Everose gold President bracelet with semi-circular three-piece links and a concealed folding Crownclasp, completing one of the most jewellery-like expressions in the current Datejust 31 range.
