Rolex Datejust 31 Everose Rolesor — Silver Diamond Dial, Fluted Bezel | Ref. 278271

The Datejust 31 in Everose Rolesor with a fluted bezel and silver diamond dial occupies a quietly prestigious position in the mid-size Rolex offering. Reference 278271 brings together the warm rose-gold tones of Rolex's proprietary Everose alloy with the cool brilliance of a silver dial set with factory diamond hour markers — a pairing that works precisely because neither element overpowers the other, allowing the fluted bezel's sculpted geometry to provide the visual anchor.

Calibre 2236 drives this reference, a movement manufactured entirely in-house and designed to meet the specific demands of Rolex's 28–34 mm ladies' and mid-size cases. Its Syloxi hairspring, produced from a silicon-based material, provides superior resistance to magnetic interference and temperature change compared to traditional metal springs, while the bidirectional Perpetual rotor keeps it wound through ordinary wrist movement. The Everose Rolesor construction pairs Oystersteel for the case body and bracelet outer links with 18 ct Everose gold for the fluted bezel and bracelet centre links — a material hierarchy that also justifies the price positioning without requiring a fully precious-metal case.

Collectors drawn to mid-size Rolex pieces appreciate that the 31 mm Datejust avoids the gender assumptions sometimes attached to the 28 mm Lady-Datejust while remaining distinctly elegant. The diamond dial on a 278271 is a factory specification, which matters enormously for authentication and resale value. Everose gold's resistance to fading — guaranteed by Rolex's proprietary alloy formulation — means this watch ages exceptionally well, retaining its warm tone for decades of daily wear.
