Lady-Datejust 26 Champagne Dial 18K Yellow Gold Steel Oyster Bracelet 179173CSO

The Rolex Lady-Datejust 26 Ref. 179173 in the CSO configuration is a quintessential Rolex model from the previous 26 mm generation, embodying classic elegance and enduring luxury. This model utilizes the traditional two-tone blend known as Yellow Rolesor (the harmonious fusion of Oystersteel and 18K Yellow Gold). The watch is instantly recognizable by its dazzling 18K Yellow Gold Fluted Bezel, a signature Rolex design element that brilliantly reflects light and adds significant textural complexity to the piece.

The dial presents the highly traditional and warm Champagne finish . This rich golden tone offers a luxurious and perfectly complementary backdrop to the yellow gold components of the case and bezel. The dial is marked by clean Applied Index Hour Markers (batons), which are meticulously set in 18K Yellow Gold. This minimalist marker set ensures superb legibility and maintains a classic, balanced proportion against the dial’s opulent finish.
