Rolex Datejust 31 Yellow Rolesor — Dark Grey Diamond Roman Six Dial

The Datejust 31 in Yellow Rolesor sits at an intriguing intersection within the lineup: not quite a ladies' watch and not yet mid-size, it serves wrists that find the 36mm case too broad without wanting to sacrifice presence. Yellow Rolesor — the combination of 904L Oystersteel and 18-karat yellow gold used on the bezel, crown, and often the bracelet center links — delivers a two-tone aesthetic that reads as genuinely luxurious rather than transitional. Against a dark grey dial with diamond-set Roman numeral six and an overall diamond index layout, the warm gold tones create a striking visual contrast.

The calibre governing this reference is the Calibre 2235, Rolex's dedicated ladies' movement historically used in the 178xxx case generation, or the Calibre 2236 for the 278xxx iteration featuring a Syloxi silicon hairspring. Both movements are self-winding, chronometer-certified to -2/+8 seconds per day, and built to Rolex's full in-house standard. The Datejust 31's Oyster case provides 100 metres of water resistance, and the fluted or smooth bezel in yellow gold adds dimensional contrast to the steel case flanks. Diamond indices on the dial are individually set and QC-checked in Rolex's Geneva workshops.

For buyers, the 31mm Datejust in Rolesor occupies a unique value proposition: it carries genuine precious metal and stone content with Rolex's documented build quality, yet trades at a notable discount versus the full gold Day-Date or larger Datejust 36. Collectors focused on factory diamond dials should verify that stones are undamaged and the dial text is unaffected by repolishing attempts, as these factors heavily influence resale stability in this segment.
