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

This variant of reference 278381RBR showcases one of the most singular dial configurations in the current Datejust 31 portfolio: a chocolate diamond-set dial paired with a 46-diamond bezel in Everose Rolesor. The deep brown tones of the dial's set diamonds create a warm, earth-toned aesthetic that plays beautifully against the rose-gold hues of the Everose metal, producing a look that is simultaneously bold and harmonious — rare in a 31 mm format.

Calibre 2236, the newest movement in the mid-size Datejust lineage, powers this reference. Its Syloxi silicon hairspring delivers approximately 55 hours of power reserve and superior resistance to magnetic disruption, while the self-winding rotor charges the mainspring efficiently through everyday motion. The chocolate diamonds on the dial are individually selected for consistency of colour and cut, set directly into the dial surface — a labour-intensive process that underscores the watch's position as a genuine jewellery-timepiece rather than a simple gem-adorned watch.

Chocolate or brown-toned diamond dials represent a relatively rare subset within the already specialist world of Datejust gem-set references, and this specific 278381RBR configuration is among the harder to locate on the secondary market. Collectors who prioritise distinctiveness over convention — and who appreciate the technical rigour behind Everose's proprietary gold composition, which resists fading unlike standard rose gold alloys — will find this reference a compelling and durable acquisition.
