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

Reference 278274 is the Datejust 31 in White Rolesor — Rolex's proprietary combination of Oystersteel and 18ct white gold — featuring a fluted white gold bezel and a black dial with Roman numeral indices. The 31mm case sits at the intersection of the brand's midsize and ladies' offerings, proportioned generously enough to wear with confidence on a broader wrist while retaining the refined elegance appropriate for evening occasions. The black Roman dial offers high contrast against the polished indices, making legibility effortless despite the dressy configuration.

Inside the 278274 runs Calibre 2236, Rolex's dedicated movement for 31mm and 28mm Datejust references. The 2236 features the Syloxi silicon hairspring — a proprietary innovation that renders the oscillator highly resistant to magnetic fields and temperature variation — along with a 55-hour power reserve. The Rolesor construction means the bezel, crown, and caseback are in white gold while the case middle and bracelet are in Oystersteel, a combination that delivers noble-metal aesthetics at a more accessible price point than a fully precious-metal reference.

The White Rolesor Datejust 31 with a fluted bezel occupies a sweet spot for collectors seeking a versatile dress watch with genuine manufacture credentials. Black Roman dials in the Datejust line tend to attract buyers who prioritise clarity and formality over decorative complexity. The 278274 is well-suited to a collector building a single-watch wardrobe where versatility between boardroom and evening is essential — and the Rolesor construction ensures the watch retains meaningful value in the secondary market.
