Rolex Lady-Datejust 28 Steel — Dark Grey Index Dial | Ref. 279160

Reference 279160 embodies the understated conviction of Rolex's all-steel proposition: a watch in which material purity, mechanical precision, and chromatic restraint are considered sufficient reasons to own it. The 28 mm Oyster case is fabricated from 904L Oystersteel — a superalloy whose resistance to corrosion and capacity to take a deep mirror polish set it apart from the 316L steel used by most watchmakers. The screw-down Twinlock crown seals the movement cavity to 100 metres, and the domed bezel preserves the case's smooth, uninterrupted arc.

Dark grey is among the most versatile and contemporary dial tones in the Datejust vocabulary. It neither absorbs light like a true black dial nor reflects it like a white one, but occupies a luminous midpoint that renders the applied index hour markers in sharp, three-dimensional contrast. The indices are polished on their visible faces and brushed on the sides — a telling detail of finish quality found throughout Rolex's current production. The date at three o'clock is enhanced by the Cyclops lens, ground into the scratch-resistant sapphire crystal with double anti-reflective coating.

The Calibre 2236 self-winding movement powers this reference. Its Syloxi silicon hairspring, developed in-house by Rolex, is antimagnetic and self-lubricating by virtue of its material properties, reducing maintenance demands while improving chronometric stability. A power reserve of approximately 55 hours, stop-seconds for synchronisation, and instantaneous date correction complete a movement specification that surpasses expectations at this price point. The five-link Jubilee bracelet in 904L steel, with its characteristically supple drape, is secured by the concealed Crownclasp for a refined finish on the wrist.
