Rolex Lady-Datejust 28 28 mm 279163CDO Steel/Yellow Gold Champagne

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, tracing its lineage to 1957 when Rolex introduced the first Datejust scaled for women. Over the decades it has remained the definitive expression of understated luxury on the wrist, worn by generations of women who value precision engineering as much as refined aesthetics. The 28 mm case size introduced with the modern Lady-Datejust generation struck an ideal balance between contemporary proportion and classical femininity, and the 279163CDO represents this philosophy at its most compelling.

The case of reference 279163CDO measures 28 mm in diameter and is crafted in Rolex's proprietary Oystersteel — a 904L stainless steel alloy chosen for its exceptional corrosion resistance and ability to take a brilliant polish — paired with 18k yellow gold on the bezel, crown, and Oyster bracelet center links. This two-tone Rolesor combination gives the watch its warm, jewellery-like character without sacrificing the robustness associated with the Datejust name. The smooth domed bezel in polished yellow gold frames the dial with a clean, uninterrupted arc of gold that enhances the sense of depth and luxury.

The champagne diamond dial is the centrepiece of the 279163CDO. Its warm, golden-hued surface catches light in a way that shifts subtly throughout the day, and the diamond hour markers add just the right measure of brilliance without veering into excess. The applied Rolex coronet sits above the dial text in classic fashion, and the characteristic magnifying Cyclops lens over the date aperture at 3 o'clock — one of the Datejust's defining signatures — makes the date instantly legible at a glance. Together, these details create a dial that is equally at home at a business lunch or a formal evening event.

Powering the Lady-Datejust 28 is a Swiss automatic movement, self-winding through the natural motion of the wearer's wrist and regulated to Rolex's exacting Superlative Chronometer standards, meaning it has been certified by Rolex to an accuracy of ±2 seconds per day after casing. The movement is protected inside the Oyster case, which is water resistant to 100 metres (330 feet), ensuring the watch can withstand splashes, rain, and recreational swimming with ease. This combination of certified precision and practical durability is precisely what has made the Datejust the world's most recognized watch.

The three-link Oyster bracelet with its alternating polished and satin-finished links provides a comfortable and secure fit on the wrist, and the concealed folding Crownclasp integrates seamlessly into the bracelet design for a clean, uninterrupted silhouette. Whether worn closely against a cuff or layered with bracelets, the 28 mm case sits flush and elegantly on even slender wrists, making the 279163CDO one of the most versatile watches Rolex produces.
