Rolex Lady-Datejust 28 Yellow Gold — Mother-of-Pearl Diamond Dial with Diamond Bezel | Ref. 279138RBR

Reference 279138RBR sits at the apex of the current Lady-Datejust 28 in yellow gold: a 44-diamond bezel surrounding a mother-of-pearl dial set entirely with diamond hour markers, the suffix 'RBR' denoting the factory-set diamond bracelet that extends the jewellery-grade treatment to the wrist. This is the Lady-Datejust as wearable jewellery, every element selected and finished to maximise brilliance and precious-metal presence within a 28 mm Oyster case.

The 18-ct yellow gold case and bracelet provide the warm tonal foundation against which the diamonds operate. The 44-diamond bezel deploys brilliant-cut stones across the entire bezel surface, while the mother-of-pearl dial — with its characteristic play of light and organic depth — hosts individually set diamond indices in place of conventional applied markers. The diamond-set President bracelet continues the jewellery theme from case to clasp. Inside, Calibre 2236 — Rolex's current-generation self-winding movement for the Lady-Datejust, featuring a Syloxi silicon hairspring — ensures that the watch's technical specification matches its material ambition.

Factory diamond-set Rolex references carry a specific appeal for collectors who want Rolex's craftsmanship and quality assurance applied to a fully jewelled watch, rather than the aftermarket setting work that pervades much of the pre-owned market. The 279138RBR in yellow gold represents an enduring configuration: warm in tone, maximally brilliant, and backed by Rolex's resale stability. For the collector of ladies' gem-set watches, this reference offers an irreducible combination of brand provenance, movement quality, and jewellery impact.
