The Rolex Lady-Datejust 26 Ref. 179173 in the CSJ configuration is a highly sought-after, classic timepiece from the previous 26 mm generation, epitomizing the brand’s iconic aesthetic. This model is constructed using the definitive two-tone composition, known as Yellow Rolesor (the harmonious fusion of Oystersteel and 18K Yellow Gold). The watch gains immediate recognition and a brilliant, sparkling effect from its iconic 18K Yellow Gold Fluted Bezel, a signature Rolex element renowned for its geometric texture and exceptional light reflection.
The centerpiece of this exquisite timepiece is the rich and traditional Gold Finish Dial . This warm, metallic hue provides an opulent and monochromatic foundation, perfectly complementing 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 luxurious finish.
