Rolex Datejust 31 White Gold — Diamond-Paved Butterfly Dial, Diamond Bezel | Ref. 278289RBR

Reference 278289RBR represents Rolex's most jewellery-forward interpretation of the Datejust 31 — a 31 mm tour de force in 18 ct white gold set with a factory diamond bezel and a diamond-paved butterfly motif dial. The butterfly design, rendered in pavé-set brilliant-cut diamonds against a polished dial surface, transforms the watch face into a work of high jewellery, while the scalloped diamond bezel reinforces its position as a serious gemological object as much as a timepiece.

The reference is driven by the Calibre 2236, Rolex's in-house movement developed specifically for the mid-size and ladies' Datejust range. Beating at 28,800 vph, the 2236 incorporates the Syloxi silicon hairspring — engineered for superior anti-magnetic and thermal stability — and delivers a 55-hour power reserve. Superlative Chronometer certification ensures accuracy to +/-2 seconds per day from the factory, a standard rarely matched in gem-set watchmaking. The white gold Oyster case provides 100 metres of water resistance, with a Twinlock crown securing the seal.

Among gem-set Rolex references, the RBR suffix denotes the presence of a factory-set diamond bezel, a distinction that carries meaningful value in the secondary market. The butterfly dial is a limited decorative configuration, making 278289RBR a standout piece for collectors who appreciate Rolex's craft at the intersection of haute joaillerie and precision watchmaking. Its white gold construction and diamond intensity ensure it will remain a centrepiece of any fine watch or jewellery collection.
