Rolex Lady-Datejust 28 White Rolesor — White Roman Diamond Bezel | Ref. 279384RBR

The Lady-Datejust 28 in reference 279384RBR exemplifies Rolex's command of jewellery-grade watchmaking within the bounds of a fully functional Swiss chronometer. The 28 mm case in White Rolesor — a combination of 904L Oystersteel and 18 ct white gold that Rolex has refined to a seamless visual unity — is crowned by a fluted bezel set with 44 brilliant-cut diamonds, each selected for colour and clarity before being pavé-set to maximise brilliance without interrupting the bezel's characteristic architecture. The result is a ring of light that frames the dial with a quiet, continuous luminosity.

The white lacquer dial, inscribed with Roman numeral hour markers in a crisp, classical typeface, invokes the tradition of grand complication pocket watches even as its sapphire crystal — fitted with a Cyclops lens and double anti-reflective coating — keeps it firmly contemporary. The Jubilee bracelet in White Rolesor, with its five-piece links of alternating brushed and polished surfaces, was designed specifically to complement the Lady-Datejust's proportions, its narrowed centre links providing elegant taper toward the concealed Crownclasp.

Inside, Calibre 2236 — introduced in 2015 as Rolex's dedicated manufacture calibre for the Lady-Datejust and Pearlmaster — drives the instantaneous date complication and provides approximately 55 hours of power reserve. The Syloxi silicon hairspring, developed by Rolex in proprietary silicon, delivers exceptional resistance to magnetic fields and temperature variation in a movement scaled specifically for the 28 mm format. A Twinlock screw-down crown seals the case to 100 metres, affirming that this watch, for all its gemological ambition, remains a tool of daily, all-weather precision.
