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

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced in 1957 as the first self-winding, waterproof wristwatch with a date display scaled specifically for the feminine wrist. Over the decades it has evolved in proportion and finishing, settling at the current 28mm case size that perfectly balances presence with delicacy. Reference 279163CSO represents the modern iteration of this legacy, pairing the classicism of the original design with contemporary materials and manufacturing standards that are second to none.

The 28mm Oyster case of the 279163CSO is constructed from a combination of Rolex's proprietary Oystersteel—a highly corrosion-resistant steel alloy in the 904L family—and 18k yellow gold. This two-tone configuration, which Rolex calls Rolesor, gives the watch a warm, luxurious character without sacrificing the everyday wearability that stainless steel provides. The case is water-resistant to 100 meters (330 feet), making it a genuinely practical companion for daily life.

The champagne dial is a defining feature of this reference. Rich and subtly luminous, the champagne finish catches light in a way that feels alive on the wrist, shifting from golden warmth under incandescent light to a more restrained elegance in natural daylight. Index hour markers—polished and precise—sit cleanly against that warm ground, ensuring legibility while maintaining an understated, jewelry-like aesthetic that distinguishes the Lady-Datejust from more sportily dialed alternatives.

Crowned by an 18k yellow gold smooth domed bezel, the 279163CSO presents a unified design language: the arc of the bezel echoes the curvature of the case flanks, and the gold of the bezel flows naturally into the gold elements of the Oyster bracelet's center links. That Oyster bracelet—flat three-piece links with alternating brushed and polished surfaces—is one of the most recognized and comfortable bracelets in the industry, renowned for its durability, secure Crownclasp, and elegant silhouette. The interplay of brushed steel and polished yellow gold throughout the bracelet mirrors the dial's own balance of warmth and precision.

Powering the 279163CSO is a Rolex automatic movement, a self-winding caliber housed within the hermetically sealed Oyster case. Rolex movements at this tier are celebrated for their chronometric accuracy, reliability, and virtually maintenance-free longevity when serviced at regular intervals. The movement winds efficiently through the motion of the wearer's wrist, meaning this watch is always ready when you are.
