Rolex Datejust 28 Platinum — Pink Roman Dial & 44-Diamond Bezel | Ref. 279136RBR

Reference 279136RBR represents the pinnacle of the Lady-Datejust 28 in terms of case material: a full platinum Oyster case paired with a 44-diamond bezel and a pink dial with Roman numeral hour markers, completed by the President bracelet. Platinum in the Lady-Datejust is a rare specification — the material's density and workability requirements mean it appears in only a select few Rolex references, always at the very top of the pricing hierarchy. The pink Roman dial introduces warmth into what might otherwise be a cool, monochromatic platinum palette, creating a considered tonal contrast that gives the watch a distinctly feminine elegance.

Inside the platinum Oyster case runs the Calibre 2236, Rolex's dedicated self-winding movement for the 28mm case size. The Calibre 2236 offers a 55-hour power reserve and features the Syloxi silicon hairspring, which is both antimagnetic and free from the need for lubrication at the escapement level. The President bracelet in platinum — with its characteristic semi-circular three-piece links — extends the monolithic precious metal aesthetic of the case, with the concealed Crownclasp preserving the uninterrupted line of the bracelet profile.

Platinum Lady-Datejust references occupy a collector niche that rarely appears on the open market. The 279136RBR is sought by buyers who have exhausted the gold spectrum and seek the understated prestige of platinum — a metal whose value derives as much from rarity of use as from its intrinsic properties. Resale demand is consistent among high-net-worth collectors, with platinum examples commanding meaningful premiums over equivalent gold configurations.
