Rolex Datejust Lady Yellow Gold — Cornflower Blue Diamond Index Dial | Ref. 279178

The Lady-Datejust 28 in 18-carat yellow gold with a cornflower blue stripe dial is one of the most visually arresting executions in the current Rolex collection — a reference that achieves chromatic boldness without sacrificing the quiet refinement the Datejust name implies. The fluted yellow gold bezel, its parallel ridges reflecting light along their crests, frames a dial in cornflower blue whose distinctive stripe pattern is achieved through a careful layering of lacquer. Diamond hour markers — 36 brilliant-cut stones in total, with an additional 8 set at the IX position — elevate the dial into jewellery territory without obscuring legibility.

Calibre 2236, the manufacture movement Rolex developed specifically for the Lady-Datejust 28, operates at 28,800 vibrations per hour and features the silicon Syloxi hairspring — a technological advancement that renders the movement impervious to magnetic fields and temperature variation while eliminating the need for periodic oiling of the hairspring. An approximately 55-hour power reserve ensures reliable running through a long weekend. The date, positioned at 3 o'clock and magnified by the Cyclops lens, advances instantaneously at midnight.

The 18-carat yellow gold Jubilee bracelet, with its five-piece semi-circular links, provides the ideal bracelet pairing for a watch of this chromatic warmth — the gold of the bracelet extending the colour story of the case and bezel in a seamless continuum. The concealed Crownclasp closes cleanly, and a scratch-resistant sapphire crystal with double anti-reflective coating offers optimal dial legibility across lighting conditions. Water-resistant to 100 metres, this Lady-Datejust 28 is as capable as it is beautiful.
