About This Watch
Platinum is the rarest case material in the Rolex Datejust programme, deployed almost exclusively in the Lady-Datejust 28 mm line and signalling the highest tier of the reference's material hierarchy. Reference 279136RBR pairs a solid platinum Oyster case with a 44-diamond bezel set with brilliant-cut stones and a dark grey dial set entirely with baguette and brilliant-cut diamonds — a combination that is as technically demanding to produce as it is visually arresting. The President bracelet, rendered in platinum, completes a watch that few retailers carry in stock.
Calibre 2236 drives this reference, Rolex's dedicated 28/31 mm movement incorporating the Syloxi silicon hairspring. The choice of silicon for the hairspring is particularly relevant in a watch likely to encounter fine jewellery and magnetic clasps; silicon is inherently non-magnetic and dimensionally stable across temperature extremes. The Oyster case maintains 100-metre water resistance through its screw-down crown — a practical feature that distinguishes this from purely decorative competitors at comparable price points.
Full platinum Datejusts with diamond bezels and diamond dials occupy the very top of the secondary-market value range within the Lady-Datejust family. Supply is extremely limited; Rolex produces these configurations in small numbers, and demand from collectors and jewellery buyers alike keeps allocation tight. For a buyer seeking a tangible store of value in wearable form, a platinum 279136RBR with full factory diamond setting represents one of the most concentrated expressions of that proposition in the Rolex catalogue.
