Rolex Datejust 31 White Gold — Diamond Bezel Mother-of-Pearl Diamond Dial | Ref. 278289RBR

At the summit of the Datejust 31 collection sits reference 278289RBR — a fully jewelled configuration in 18ct white gold with a diamond-set bezel and a mother-of-pearl dial set with diamond hour markers. The 278289RBR designation signals a factory-diamond bezel (RBR indicating ruby/diamond set), and the mother-of-pearl dial adds a second layer of luminosity, its iridescent surface shifting through blue, cream, and silver tones depending on the angle of light. This is the Datejust at its most haute-joaillerie, conceived for occasions where a timepiece is expected to double as fine jewellery.

Calibre 2236 drives the watch with the same mechanical discipline found across the 31mm Datejust family. The Syloxi silicon hairspring ensures the movement remains unaffected by magnetic exposure — a practical benefit even for a watch of this decorative character. The President bracelet in white gold, with its three-piece semi-circular links, is the natural companion for a fully precious-metal Datejust, providing both comfort and the visual continuity that makes the bracelet and case read as a unified whole.

Within the pre-owned market, diamond-bezel Datejust references in white gold with mother-of-pearl dials command consistent demand from buyers seeking a watch that functions simultaneously as jewellery. The 278289RBR is an obvious choice for a formal wardrobe anchor, yet its Oyster case robustness means it is not restricted to occasional wear. Collectors who view watches as wearable art will find this reference rewarding; those focused purely on resale metrics should note that factory diamond variants retain value more reliably than aftermarket-modified alternatives.
