Rolex Datejust White Rolesor — Aubergine Roman Diamond 6 Dial | Ref. 278344RBR

Among the most artistically distinctive executions in the Datejust 31 collection, this White Rolesor reference pairs an Oystersteel monobloc middle case with 18 ct white gold crown, bezel lugs and bracelet centre links — the signature two-tone composition Rolex has refined for decades. The domed bezel is pavé-set with 24 brilliant-cut diamonds, their cold northern fire perfectly matched to the white gold's polished surfaces. At 31 mm, the case proportion sits precisely at the intersection of contemporary sport and classical dress sensibility, sealed to 100 metres via a screw-down Twinlock crown.

The dial is finished in a deep aubergine lacquer, a colour associated with the great gem-set Datejust variants of the late twentieth century and one of the rarest chromatic choices in the current catalogue. Roman numerals are applied in polished white gold with the exception of the six-o'clock position, where eleven brilliant-cut diamonds replace the numeral entirely — a deliberately asymmetric flourish that draws the eye down the vertical axis of the dial. The date aperture at three o'clock is magnified through the characteristic Cyclops lens integrated into the scratch-resistant sapphire crystal.

Power comes from Calibre 2236, Rolex's manufacture movement developed specifically for 31 mm lady's and mid-size Datejust references. The silicon Syloxi hairspring renders the oscillator impervious to magnetic fields while contributing to the approximately 55-hour power reserve. An Oystersteel Jubilee bracelet with five-piece semi-circular links and a concealed folding Crownclasp completes the ensemble, offering the supple drape and durable construction for which the Jubilee configuration has been celebrated since 1945.
