Rolex Datejust 28 Steel — Silver Roman Dial | Ref. 279160

Reference 279160 is Rolex's entry point into the Lady-Datejust range — a 28mm Oystersteel watch with a domed bezel and silver dial in Roman numerals that represents the model in its most accessible, understated form. Introduced as part of the 279xxx generation, this reference brought the Lady-Datejust into line with the current Calibre 2236 era while maintaining the classically proportioned 28mm case that has defined the smaller Datejust for decades.

Powering the 279160 is Calibre 2236, developed by Rolex specifically for their smaller-cased ladies' models. It incorporates the Syloxi hairspring — a silicon component manufactured in-house using photolithography — which provides superior resistance to magnetic fields, shocks, and temperature fluctuations compared to traditional metal hairsprings. The 55-hour power reserve exceeds many larger-movement competitors. The all-steel Oystersteel construction delivers the material's characteristic resistance to corrosion and deformation, and the silver Roman dial presents crisp, high-contrast legibility.

For buyers new to the Datejust, the 279160 presents the purest expression of the model without gem-set embellishment or precious metal price premiums. It is also among the most versatile references in the range — equally at home with casual and formal attire. Pre-owned examples in excellent condition represent genuine value in the wider Rolex market, as the combination of a current-generation calibre, durable steel construction, and timeless dial design ensures long-term relevance.
