Rolex Datejust White Rolesor — Aubergine Roman Diamond 6 | Ref. 278384RBR

White Rolesor — Rolex's proprietary combination of Oystersteel and 18 ct white gold — defines the aesthetic character of reference 278384RBR, a Datejust 31 that bridges the gap between sporty versatility and jewellery-grade refinement. The 31 mm Oyster case unites the polished surfaces of white gold on the bezel, crown and middle-link of the bracelet with the satin-brushed durability of Oystersteel on the flanks and lugs, creating a two-material dialogue that has been a hallmark of Rolex design since the 1970s. The diamond-set bezel elevates the reference into fully gem-set territory, each stone precisely pavé-set by the Genevieve workshops.

The aubergine dial is one of the more characterful colour choices in the Datejust spectrum — a deep, wine-tinged purple that shifts in hue according to the quality of ambient light. Roman numeral hour markers, themselves diamond-set at the 1, 2, 4, 5, 7, 8, 10 and 11 o'clock positions, complement the rich ground of the dial, while a single diamond at the six o'clock position adds a discrete point of brilliance. The Cyclops date lens at three o'clock completes the traditional Datejust signature.

Calibre 2236 — Rolex's dedicated 31 mm movement — provides the motive force, its Syloxi hairspring offering exceptional resistance to magnetic interference and temperature fluctuation. The 55-hour power reserve ensures reliable autonomy through weekend wear without winding, while the Jubilee bracelet, with its five-piece links in White Rolesor, provides a supple and secure fit that complements the dressy character of this reference.
