Rolex Datejust Everose Rolesor — Chocolate Index Dial | Ref. 279381RBR

Rolesor — Rolex's proprietary pairing of 904L Oystersteel with 18K gold — achieves particular warmth in the Everose iteration, where the rose-tinted alloy is formulated with a higher platinum content to resist fading over decades of wear. The Lady-Datejust 28 in reference 279381RBR exemplifies this philosophy: a 28mm monobloc Oystersteel middle case is crowned by an 18K Everose gold bezel set with graduated brilliant-cut diamonds, creating a tonal harmony that is simultaneously precious and restrained. The screw-down Twinlock crown, constructed in Everose gold, maintains water resistance to 100 metres.

Powering the piece is Calibre 2236, a movement designed specifically for Rolex's smaller-diameter watches and featuring the Syloxi hairspring — a silicon component of patented geometry that endows the oscillator with magnetic resistance and thermal stability far exceeding conventional alloys. The instantaneous date mechanism advances sharply at midnight with no creeping transition, while the stop-seconds function allows time-setting to the nearest second. Precision is rated at -2/+2 seconds per day after casing, with a power reserve of approximately 55 hours.

The rich chocolate dial, its lacquered surface conveying depth and understated luxury, carries applied index hour markers in Everose gold — a deliberate choice that unifies the dial with the case metal and the five-piece Jubilee bracelet. The Jubilee, a design that debuted alongside the original Datejust in 1945, here appears in white Rolesor combination, its alternating Oystersteel and Everose gold links secured by a concealed Crownclasp. The result is a Lady-Datejust of considerable sophistication, balancing gemological theatre with everyday horological utility.
