Rolex Datejust 31 White Rolesor — Dark Grey Diamond Dial, Fluted Bezel | Ref. 278274

Reference 278274 configures the Datejust 31 in White Rolesor with a fluted bezel and a dark grey diamond-set dial — a pairing that prioritises contemporary sophistication over classical warmth. Dark grey dials have gained traction across the Datejust range in recent years precisely because they offer an alternative to the dominant silver and white tones without the stronger commitment of black. Against a white Rolesor case and fluted bezel, this particular grey creates a layered, smoky aesthetic in which the diamond hour markers appear to float rather than punctuate. The 31mm diameter makes this a genuinely versatile piece.

The Calibre 2236 is the movement of record for the current Datejust 31 range. It is a self-winding Manufacture Rolex calibre incorporating a Syloxi silicon hairspring — a component that eliminates concerns around magnetic fields and lubricant degradation that affected older lever escapements. With 55 hours of power reserve and Superlative Chronometer certification, the movement performs to a standard that exceeds conventional COSC requirements by a meaningful margin. The 31mm Oyster case retains the screw-down Twinlock crown and sapphire crystal with Cyclops lens, and water resistance to 100 metres is standard.

For collectors and buyers, the 278274 occupies a mid-tier within the current Datejust jewellery segment — more nuanced in its dial colour choice than white or silver, but not as optically dramatic as the full black variants. The dark grey and white Rolesor combination is likely to age well because it avoids the extremes that can limit wearing versatility. Resale demand for diamond-dial Datejust 31 references remains healthy, and the white Rolesor bezel adds intrinsic material value that steel-only configurations cannot match.
