Rolex Datejust 31 White Gold — Dark Grey Roman Dial, Diamond Bezel | Ref. 278289RBR

Reference 278289RBR presents the Datejust 31 in full 18k white gold, configured with a diamond-set bezel and a dark grey Roman numeral dial. The Roman hour markers on a slate-grey lacquer ground create a formal, almost austere aesthetic that differentiates this piece sharply from the bright dial variants in the Datejust range. White gold amplifies this severity: cold and precise, it suits those who prefer their jewellery understated and architectural rather than decorative.

White gold construction throughout means the 31 mm Oyster case, bezel setting, and President bracelet share the same material — a detail that matters in both visual coherence and long-term wear characteristics. Calibre 2236 inside the case provides approximately 55 hours of power reserve via its Syloxi silicon hairspring. The diamond bezel on the RBR variant is set with brilliant-cut stones across a full 360-degree ring, certified under Rolex's rigorous internal gem standards.

For the collector focused on white metals, the 278289RBR is a sophisticated choice that reads as jewellery at close range but maintains clean legibility as a watch. The dark grey Roman dial is a less common configuration, which can make NOS or near-mint examples harder to locate. White gold Datejust 31s with full diamond bezels appeal strongly to buyers in Asia and the Middle East, sustaining healthy secondary market demand globally.
