Rolex Datejust 31 White Rolesor — White Roman Dial, Fluted Bezel | Ref. 278274

Few combinations in modern watchmaking convey understated luxury quite like Rolex's White Rolesor — the harmonious pairing of corrosion-resistant 904L Oystersteel with 18K white gold. In the Datejust 31 reference 278274, this two-tone philosophy expresses itself with singular polish: a 31mm case whose monobloc middle is rendered in steel, while the fluted bezel and crown are crafted in white gold, creating a play of contrasting brightness that animates the wrist throughout the day.

Within the sealed case resides Calibre 2236, Rolex's in-house movement developed specifically for the mid-size and ladies' Datejust collections. The 2236 incorporates the Syloxi silicon hairspring — a proprietary component that delivers exceptional resistance to magnetic fields and temperature variation — while offering approximately 55 hours of power reserve. The white lacquer dial carries crisp Roman numerals in applied relief, conferring classical legibility against the clean ground.

The five-piece Jubilee bracelet in White Rolesor, secured by a concealed Crownclasp, completes an ensemble that is simultaneously precise in its engineering and gracious in its form. Reference 278274 is a study in Rolex's mastery of materials, movements, and proportion — a 31mm statement of enduring refinement.
