Rolex Lady-Datejust White Rolesor — White MOP Diamond Dial, Fluted Bezel | Ref. 279174

The Lady-Datejust 28 reference 279174 in White Rolesor distils the collection's gem-set DNA into the most intimate canvas in the Datejust family. At 28 mm, the case proportion is quintessentially jewellery-adjacent, and this configuration exploits that scale with a white mother-of-pearl dial pavé-set with diamond hour markers — the iridescent, organic quality of the MOP base contrasting beautifully with the geometric precision of brilliant-cut diamonds — all framed by a fluted white gold bezel.

The Calibre 2236 self-winding movement powers the 279174, a modern evolution of the 2235 that Rolex introduced for the Lady-Datejust 28 generation. The 2236 features a silicon Syloxi hairspring — a Rolex-patented advance that replaces conventional metal with a silicon component offering superior resistance to shocks, temperature variation, and magnetic fields, while also contributing to reduced service intervals due to its self-lubricating properties. Beating at 28,800 vph with a 55-hour power reserve, the 2236 represents a meaningful technical advance over its predecessor.

The Lady-Datejust 28 generation, introduced in 2017 alongside the Calibre 2236, offered Rolex an opportunity to refresh the brand's small-dial proposition with both the latest movement technology and updated case geometry. Reference 279174 in mother-of-pearl and diamond is among the more collectible configurations in the 28 mm range, combining the intrinsic value of White Rolesor construction with the aesthetic complexity of a gem-set dial. For collectors and gift-buyers alike, this reference represents the Lady-Datejust at its most fully realised.
