Rolex Lady-Datejust 28 Platinum — 44-Diamond Bezel, White Roman Dial | Ref. 279136RBR

Reference 279136RBR represents the pinnacle of the Lady-Datejust 28 range, executing the model in platinum — a metal Rolex reserves exclusively for its most prestigious configurations. The 44-diamond bezel, set with brilliant-cut stones in a precise pavé arrangement, creates an unbroken ring of light around the dial. Within, a white dial carries Roman numeral hour markers, a layout that references classical watchmaking traditions and lends a formal, timeless character to the watch.

Platinum as a case material offers unique properties: denser than gold, naturally white without requiring plating, and resistant to surface oxidation over time. On the wrist it carries a perceptible weight that distinguishes it from white gold alternatives. The Calibre 2236 — Rolex's in-house movement for the ladies' and mid-size range — provides 55 hours of power reserve, the Syloxi silicon hairspring, and COSC-level chronometric certification. The President bracelet, exclusive to Day-Date and platinum or gold Lady-Datejust models, accompanies this reference as expected for a platinum-cased configuration.

Platinum Datejust references are produced in significantly smaller quantities than their gold and steel counterparts, making them sought after by collectors who prioritise rarity alongside refinement. The 279136RBR is a watch that sits comfortably across formal and semi-formal contexts, carrying investment-grade material value with genuine horological substance.
