Rolex Lady-Datejust 31 31 mm 278273CSO Steel/Yellow Gold Champagne

The Rolex Lady-Datejust is one of the most iconic timepieces in the history of Swiss watchmaking. Introduced in 1957 as the first self-winding, waterproof, and date-displaying wristwatch sized specifically for women, the Lady-Datejust has defined refined femininity on the wrist for nearly seven decades. Reference 278273CSO represents the contemporary 31mm generation of this storied line, offering a case size that sits beautifully on a wide range of wrists while commanding genuine presence.

The 31mm case of reference 278273CSO is constructed from Rolex's proprietary Oystersteel — a corrosion-resistant 904L stainless steel alloy — complemented by polished yellow gold accents that run through the fluted bezel and select bracelet components. The yellow gold fluted bezel is one of the most recognizable design signatures in Rolex's vocabulary, originally engineered to screw the crystal onto the case and later retained for its timeless aesthetic appeal. Together, the steel and gold create the classic two-tone Rolesor combination that has captivated collectors for generations.

The champagne dial is the visual heart of the 278273CSO. Warm and luminous, a champagne finish interacts beautifully with yellow gold indices and hands, creating an atmosphere of understated luxury that reads clearly across every lighting condition. Rolex's meticulous dial craftsmanship ensures flawless finishing, depth of color, and the precise application of every applied marker — details that distinguish a genuine Rolex from any imitation.

Powering the watch is an automatic movement, the hallmark of Rolex's commitment to self-sufficiency and engineering excellence. The watch is also rated to 100 meters (330 feet) of water resistance courtesy of the legendary Oyster case architecture — its screw-down crown and caseback forming a hermetic seal that protects the movement from dust, moisture, and pressure. The Oyster bracelet, also in Oystersteel and yellow gold, offers both security and comfort, fastening with Rolex's precision-engineered folding clasp.

For collectors and first-time Rolex buyers alike, the Lady-Datejust 31 in reference 278273CSO is one of the most versatile luxury watches on the market. Its two-tone construction bridges sportiness and formality; its 31mm footprint suits those who prefer a refined silhouette; and the champagne dial ensures it pairs effortlessly with a broad wardrobe. Whether acquired as a personal milestone, a gift, or a long-term investment piece, this reference holds its desirability across seasons and trends.
