Rolex Lady-Datejust 28 Yellow Gold — 44 Diamond Bezel Lilac Stripe Diamond Index | Ref. 279138RBR

Few dial finishes in Rolex's current catalogue achieve the chromatic complexity of the lilac stripe diamond index configuration on this Lady-Datejust 28 in yellow gold — a treatment that layers three discrete visual registers into a coherent design. The dial ground is a striated lilac, its alternating light and shadow bands produced by a fine guilloche-adjacent surface preparation that creates movement as the watch turns on the wrist. Against this animated background, factory-fitted diamond hour markers break each stripe with points of white light, their settings invisible from above so that each stone appears to float within the lacquered field.

The 44-diamond bezel on reference 279138RBR employs brilliant-cut stones grain-set into an 18 ct yellow gold ring, the warm metal providing a counterpoint to the cool lavender-pink of the dial. Yellow gold's saturation of colour — its ability to anchor and frame the surrounding gemstones without competing with them — is precisely the reason Rolex's gem-set Lady-Datejust specifications so frequently pair this metal with jewel-rich dials rather than white gold. The Jubilee bracelet, with its characteristic five-piece link construction, continues the yellow gold through to the double-folding Crownclasp.

Calibre 2236 drives this 28 mm timepiece, its Syloxi hairspring — a silicon oscillating component manufactured to Rolex's tolerances through a proprietary deep-reactive-ion etching process — providing the movement with superior isochronism across positional changes and a resistance to magnetic fields that ferrous hairsprings cannot replicate. A 55-hour power reserve and a rapid date-set function via the crown complete the practical specification of a watch whose visual register is squarely in the jewellery tier but whose mechanical credentials are uncompromisingly horological.
