Rolex Datejust 31 Everose Rolesor — Rose Roman Dial, 46-Diamond Bezel | Ref. 278381RBR

Among the most romantically conceived entries in the modern Datejust 31 catalogue, reference 278381RBR pairs Everose Rolesor construction — Oystersteel and Rolex's proprietary 18ct Everose gold alloy — with a factory-set 46-diamond bezel and a rose-hued Roman numeral dial whose warm palette mirrors the pink gold tones of the case and crown. The result is a watch of carefully calibrated visual coherence, where every material choice reinforces the next.

Driving the 278381RBR is Calibre 2236, the current-generation movement for 31 mm Datejust models, featuring a silicon Syloxi hairspring that offers improved thermal stability and resistance to magnetic interference compared to its Parachrom predecessor. The self-winding mechanism provides approximately 55 hours of power reserve — a meaningful upgrade over the older 2235. The diamond bezel's 46 brilliant-cut stones are individually set and graded to Rolex's strict internal standards, while the Rolesor Jubilee bracelet blends polished Everose links with brushed steel for tactile and visual contrast.

Reference 278381RBR with the rose Roman dial is a configuration that attracts collectors drawn to tonal harmony rather than high contrast. The warm-rose, gold, and diamond combination reads as precious without being ostentatious, and the Everose Rolesor format delivers gold presence at a more accessible price point than a full-gold reference. Well-preserved examples in original condition with boxes and papers consistently command strong premiums in the current market.
