Rolex Datejust Yellow Rolesor — Fluted Bezel Mother-of-Pearl Diamond Dial | Ref. 278273

Yellow Rolesor — the combination of Oystersteel and 18 ct yellow gold — occupies a singular position in Rolex's material hierarchy: more precious than monochromatic steel, yet retaining the robustness and affordability of Oystersteel for the bulk of the case construction. On reference 278273, the yellow gold is deployed on the fluted bezel and the centre links of the Jubilee bracelet, creating a two-tone rhythm that has attracted admirers since the Rolesor concept was first introduced in the 1930s. The 31 mm case is a contemporary Datejust proportion that comfortably bridges the Lady-Datejust 28 and the Datejust 36.

The dial is among the most lavishly appointed in the current 278273 range: a mother-of-pearl ground of natural iridescence is set with diamond hour markers, individually selected for cut uniformity and brightness, eliminating conventional applied indices in favour of pure gem-set points of light. The fluted bezel, in 18 ct yellow gold, introduces a further layer of textural contrast above the smooth Oystersteel case flanks. The date window at three o'clock is framed by a Cyclops lens magnifying the date 2.5 times for effortless legibility.

Calibre 2236 — Rolex's purpose-built movement for mid-size Datejust references — provides the mechanical foundation, with its Syloxi silicon hairspring offering antimagnetic performance and chronometric stability across a 55-hour power reserve. The Jubilee bracelet in Oystersteel and yellow gold articulates with exceptional fluidity, secured by the double-locking Crownclasp. Reference 278273 is a watch that performs with tool-watch dependability while presenting with the confidence of fine jewellery.
