The Rolex Lady-Datejust reference 279175-0023 is a 28mm luxury timepiece crafted from 18k Everose gold, a proprietary rose gold alloy designed to retain its luster over time. This model features a signature fluted bezel and an Oyster case construction with a monobloc middle case, screw-down case back, and a Twinlock double waterproofness system. The dial is a notable highlight, featuring a diamond-pave setting adorned with 291 diamonds and applied 18k Everose gold Roman numeral hour markers. The watch is paired with a solid gold President bracelet, characterized by semi-circular three-piece links and a concealed folding Crownclasp.
The timepiece is powered by the Rolex caliber 2236, a self-winding mechanical movement that is COSC-certified and further tested by Rolex as a Superlative Chronometer. This movement incorporates a patented Syloxi hairspring in silicon and high-performance Paraflex shock absorbers to ensure stability and precision of -2/+2 seconds per day. It offers a power reserve of approximately 55 hours and includes complications such as a central hour, minute, and seconds hands, alongside an instantaneous date display visible through a Cyclops magnifying lens at the 3 o’clock position. The watch also features a stop-seconds function for precise time setting and is water-resistant up to 100 meters.
General reviews of the Lady-Datejust 28 series often emphasize its blend of classic elegance and robust technical performance, making it a highly regarded choice for a versatile daily luxury watch. Critics and collectors frequently praise the comfort and refinement of the President bracelet, as well as the intricate craftsmanship of the diamond-pave dial. The model is recognized for its timeless aesthetic that remains relevant across generations, though its premium price point and the specific 28mm size are often noted as factors that cater primarily to those seeking a delicate yet prestigious statement piece.
