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

Platinum construction distinguishes Reference 279136RBR from nearly all other Lady-Datejust offerings — Rolex uses platinum extremely selectively, reserving it for references at the absolute summit of the collection. The 28 mm case in 950 platinum, a metal denser and rarer than gold, carries a weight and lustre that experienced collectors identify immediately upon handling. A 44-diamond bezel and a mother-of-pearl diamond-set dial on a President bracelet in platinum complete a specification that places this reference among the most precious Lady-Datejust configurations available.

Calibre 2236 — Rolex's compact ladies' automatic — runs at 28,800 vph with a 55-hour power reserve, supported by the silicon Syloxi hairspring for magnetic immunity. The 44-stone brilliant-cut diamond bezel is set in platinum, matching the case and bracelet metal throughout for complete aesthetic coherence. The mother-of-pearl diamond dial presents hour markers in additional brilliant-cut diamonds; the dial surface itself shifts colour with light angle, providing a dynamic visual depth that no lacquered or enamel dial can replicate. The platinum President bracelet — semi-circular three-piece links in the same metal — drapes with authority rarely found in watches of this size.

Platinum Lady-Datejust references occupy a niche that even seasoned Rolex collectors occasionally overlook, which creates asymmetric opportunity on the secondary market. Platinum Rolex pieces are produced in far smaller volumes than their gold counterparts, and 279136RBR with full diamond configuration represents the peak of accessible-format Rolex luxury. Complete set examples with papers confirming platinum specification are accorded material premiums by specialist dealers.
