Rolex Lady-Datejust White Rolesor — Diamond Bezel Silver Index Dial | Ref. 278384RBR

Reference 278384RBR delivers one of the most classically proportioned Lady-Datejust configurations in the current catalogue. White Rolesor — Rolex's pairing of Oystersteel with 18k white gold for the crown, bezel setting, and bracelet centre links — creates a monochromatic, near-platinum aesthetic at a meaningful cost advantage over solid white gold. The RBR factory diamond bezel installs 44 brilliant-cut diamonds into the bezel ring, while the silver dial with index hour markers provides the clean, uncluttered backdrop that allows the gem-set bezel to command appropriate attention.

Calibre 2236, purpose-built for the 28mm and 31mm Lady-Datejust platform, powers this reference with its Syloxi silicon hairspring offering resistance to magnetic fields and temperature variation superior to traditional alloy hairsprings. The 31mm Oyster case in White Rolesor maintains 100 metres of water resistance, and the Jubilee bracelet — in matching Rolesor configuration — delivers the signature five-link articulation that has defined Datejust bracelet engineering since 1945. Factory finishing on both case and bracelet alternates polished and brushed surfaces to maximise visual depth.

For buyers seeking a Lady-Datejust with genuine diamond presence at a price point below full white gold references, the 278384RBR in White Rolesor represents intelligent market positioning. The silver index dial is the most versatile choice within the range — compatible with any wardrobe, any occasion — while the diamond bezel elevates the piece clearly into jewellery-watch territory. Factory RBR bezels carry a meaningful premium in the secondary market, and White Rolesor references remain consistently sought-after, ensuring strong resale fundamentals for this configuration.
