The Rolex Lady-Datejust 28 reference 279173CSO represents one of the most enduring expressions of understated luxury in modern watchmaking. Introduced as an evolution of the original Lady-Datejust—itself a descendant of the 1945 Datejust, the world's first self-winding wristwatch to display the date in a window on the dial—the 28mm case size strikes an ideal balance between classic femininity and contemporary wrist presence. Reference 279173CSO brings together Oystersteel and 18k yellow gold in a configuration that honors decades of Rolex two-tone tradition.

The case measures 28mm in diameter and is constructed from Rolex's proprietary Oystersteel, an alloy from the 904L steel family celebrated for its exceptional corrosion resistance and high-polish brilliance. The integration of 18k yellow gold on the bezel and crown winding components creates a warm, luxurious contrast with the cooler steel case flanks, making the 279173CSO immediately recognizable as a Rolesor model—Rolex's term for its signature steel-and-gold combination.

The champagne dial is among the most versatile and sought-after dial options in the Lady-Datejust collection. Its warm golden-beige hue complements the 18k yellow gold fluted bezel and the two-tone case, creating a cohesive, sun-drenched aesthetic. Index hour markers provide clean legibility, and the iconic Cyclops lens over the date window at 3 o'clock magnifies the date 2.5× for effortless reading—a signature Rolex detail that has distinguished the Datejust for decades.

Powering the Lady-Datejust 28 is a certified Swiss automatic movement, bearing the Superlative Chronometer certification from Rolex—a designation that requires passing the brand's in-house testing beyond the standards set by COSC. The Oyster bracelet, with its characteristic three-piece flat-link design and fold-over Crownclasp, delivers exceptional comfort and security on the wrist, and is finished to complement the two-tone case and bezel with matching steel and yellow gold links.

For collectors and first-time buyers alike, the Lady-Datejust 28 ref. 279173CSO represents a sound and stylish acquisition. Its two-tone Rolesor configuration, champagne dial, and fluted bezel make it highly versatile and perennially desirable on the secondary market. At Bizak & Co., we specialize in pre-owned and secondary-market luxury timepieces, offering knowledgeable guidance and a curated selection.
