Rolex Lady-Datejust 28 28 mm 279171CDO Steel/Rose Gold Chocolate Rolex Lady-Datejust 28 28 mm 279171CDO Steel/Rose…

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking, having established the template for the elegant, date-displaying dress watch for women since the Lady-Datejust's introduction in 1957 — itself an evolution of the original Datejust that debuted in 1945 as the world's first self-winding wristwatch to display the date through a window at 3 o'clock. Across decades, the Lady-Datejust has remained a benchmark of refined timekeeping, and the contemporary 28mm generation — introduced to replace the earlier 26mm case — brings the proportions into harmony with modern tastes while retaining every hallmark of the line's heritage. Reference 279171CDO sits squarely within this tradition, representing the collection at its most glamorous.

At 28mm, the case of the 279171CDO is crafted in a combination of Oystersteel — Rolex's proprietary 904L stainless steel alloy prized for its exceptional corrosion resistance and lustrous polish — and 18k Everose gold, Rolex's exclusive rose-gold alloy formulated to maintain its warm pink hue over time without fading. This two-tone construction, sometimes referred to by collectors as the Rolesor configuration, brings warmth and visual richness without the full heft of an all-gold piece. The Oyster case is hermetically sealed and water resistant to 100 meters (330 feet), making it as capable as it is beautiful.

The dial is where this particular reference truly distinguishes itself. The deep chocolate tone creates an immediate sense of warmth and luxury, and the diamond hour markers — a hallmark of the CDO designation — scatter light with every movement of the wrist, elevating this Lady-Datejust well beyond a simple dress piece into genuine jewelry-watch territory. The date aperture at 3 o'clock remains crisp and legible, underpinned by the Cyclops lens on the sapphire crystal that magnifies the date 2.5× for effortless reading. The overall effect is one of sumptuous, understated glamour.

The fluted bezel rendered in 18k Everose gold is among the most recognizable design elements in the entire Rolex catalogue, tracing its lineage back to the very earliest Datejust models. Originally a functional feature designed to assist with case opening, the fluted bezel evolved into the defining aesthetic flourish of the Datejust line. On the 279171CDO, executed in Everose gold, the fluting catches light dynamically and creates a brilliant frame for the chocolate dial, completing a color story of warm rose and rich brown that feels immediately coherent and luxurious. The Oyster bracelet — Rolex's three-link sports-and-dress hybrid — provides a secure, comfortable fit and echoes the two-tone construction of the case.

Powering the 279171CDO is a Rolex automatic movement, a self-winding caliber reflecting the brand's decades of in-house manufacture and certified to Superlative Chronometer standards — meaning it has passed Rolex's own rigorous testing protocol beyond the COSC certification, achieving accuracy of approximately −2/+2 seconds per day on the wrist. The movement winds automatically via the wearer's natural motion, ensuring reliability for daily wear without the need for manual winding.
