Overview
The Rolex Lady-Datejust 28 reference 279160 is a 28 mm Oystersteel dress watch that sits at the heart of Rolex's long-running Lady-Datejust collection. Powered by the in-house Calibre 2236, it pairs horological substance with a refined aesthetic suited to everyday elegance. A broad palette of dial options — spanning silver, blue, black, and pink — ensures the reference accommodates a wide range of personal tastes.
History
The Lady-Datejust traces its origins to the mid-twentieth century, when Rolex introduced a smaller-cased counterpart to the iconic Datejust for a female clientele. Reference 279160 arrived as part of a broader 2015 refresh that standardised the case diameter at 28 mm across the Oystersteel Lady-Datejust range, replacing earlier 26 mm references. The introduction of Calibre 2236 — featuring a Syloxi silicon hairspring developed in-house — marked a meaningful technical upgrade for the line. The reference has remained in continuous production since its introduction, cementing its status as the entry point into the Lady-Datejust family.
Notable points
- Calibre 2236 incorporates a Syloxi silicon hairspring, offering improved resistance to magnetic fields and temperature variation compared to traditional alloy hairsprings.
- The 28 mm Oystersteel case uses Rolex's proprietary 904L steel, known for its corrosion resistance and high-polish finish.
- Reference 279160 represents the Oystersteel-only configuration of the Lady-Datejust 28, distinguishing it from precious-metal and two-tone variants within the same model family.
- Dial variety is a defining characteristic: silver, blue, black, and pink options allow the same reference number to present markedly different characters on the wrist.
- As a dress watch, the Lady-Datejust 28 carries the Datejust's signature date window with a Cyclops lens, a detail that has defined the line since the original Datejust of 1945.
