Rolex Datejust 31 Everose Gold — Rose Diamond Dial | Ref. 278285RBR

Reference 278285RBR presents the Datejust 31 in 18ct Everose gold with a diamond-set bezel and a rose diamond dial — a configuration that explores the warm chromatic range of rose and pink with remarkable precision. The rose diamond dial, set entirely with brilliant-cut diamonds in Everose gold mounts, produces a flush, shimmering surface that appears monolithic in subdued lighting but reveals individual stones under direct light. Paired with the Everose gold case, the effect is a watch of deeply cohesive visual character.

The Calibre 2236 powers this reference, a movement developed specifically for Rolex's 26–34 mm case range. Its defining technical feature is the Syloxi silicon hairspring — conceived and manufactured by Rolex using microfabrication technology — which provides superior resistance to temperature variation, magnetic interference, and physical shocks. The 55-hour power reserve and 28,800 vph beat rate ensure consistent performance, while the Superlative Chronometer certification confirms precision within ±2 seconds per day. The Oyster bracelet in 18ct Everose gold provides secure closure via the Oysterclasp with Easylink extension.

Among 31 mm Datejust references, diamond-dial examples in full Everose gold represent the upper end of the model's value range. The RBR designation and rose diamond combination attract buyers seeking a fully coordinated colour palette rather than the more contrasting effects of steel-and-gold configurations. Appreciation potential is solid given the precious metal content and the sustained collector interest in diamond-set Rolex dials.
