Rolex Datejust 31 Everose Rolesor — Silver Diamond Dial with 24-Diamond Bezel | Ref. 278341RBR

Reference 278341RBR represents one of the more jewel-intensive configurations available in the Datejust 31 lineup: a 24-diamond bezel in Everose gold set against a silver dial bearing diamond hour markers. Everose Rolesor — Rolex's proprietary 18 ct rose gold alloy applied to the bezel, crown, and Jubilee bracelet centre links against an Oystersteel case body — delivers a warm, rose-tinted contrast that has become strongly associated with the current generation of Rolex gem-set pieces. The 278341RBR's diamond bezel is factory-set to Rolex's exacting standards, with each stone selected for cut, clarity, and colour consistency.

The Calibre 2236, developed by Rolex for the mid-size Datejust family, provides the movement specification. Its Syloxi silicon hairspring offers enhanced anti-magnetic properties relative to traditional metallic hairsprings, and its 55-hour power reserve is among the best in this movement class. Running at 28,800 vph, the 2236 meets Rolex's Superlative Chronometer standard of +/- 2 seconds per day, certified by Rolex's own testing programme conducted after full watch assembly rather than movement-only testing. The Jubilee bracelet in Everose Rolesor completes the bracelet pairing most suited to the case material combination.

Collectors and buyers assessing 278341RBR should note that factory diamond bezels are among the most closely scrutinised authenticity indicators in the Datejust market. Rolex's setting is identifiable through consistent prong height, stone uniformity, and the specific gold alloy used in the setting itself. This configuration appeals to buyers who want a Datejust that reads as a jewellery piece in formal contexts while remaining practically wearable day-to-day — a balance the 31 mm case and Rolesor construction achieves with considerable success.
