Rolex Datejust 31 Everose Rolesor — Fluted Bezel Rose Index Dial | Ref. 278271

Introduced as part of the 2019 Baselworld collection, Reference 278271 extends the Datejust 31's Rolesor tradition into the Everose generation. Rolesor — Rolex's term for the combination of Oystersteel and 18K gold — here deploys Oystersteel for the case middle and Everose gold for the fluted bezel and bracelet centre links, creating a warm two-tone composition that is simultaneously sportive and refined. The white dial, set with applied rose-gold index hour markers and a date aperture at 3 o'clock, is clean and legible — a counterpoint to the textured luxury of the Everose elements surrounding it.

Beneath the scratch-resistant sapphire crystal ticks Calibre 2236, Rolex's manufacture self-winding movement developed specifically for the 31mm Datejust. This calibre incorporates the Syloxi silicon hairspring — Rolex's proprietary innovation replacing the Parachrom hairspring in smaller-diameter calibres — delivering superior magnetic resistance and long-term rate stability. A power reserve of 55 hours, the stop-seconds complication, and instantaneous date correction round out a specification that is genuinely impressive relative to the case size.

The Jubilee bracelet in Everose Rolesor — alternating Oystersteel and Everose links — mirrors the case's two-tone theme and adds tactile richness to the wrist experience. The concealed Crownclasp ensures a smooth, uninterrupted profile from the underside. Reference 278271 occupies an important position in the Datejust 31 collection as a Baselworld 2019 debut piece, representing Rolex's first systematic application of the Syloxi hairspring to the Datejust family — technically significant, aesthetically timeless.
