Lady-Datejust 26 White Numerals Dial 18K Yellow Gold Oyster Bracelet 179173WRO

The Rolex Lady-Datejust 26 Ref. 179173 in the WRO configuration is a highly classic and refined timepiece from the previous 26 mm generation, known for its crisp contrast and iconic design. 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 beautiful White Dial. This bright, clean color provides superb contrast and a timeless, legible aesthetic. The dial is marked by traditionally styled, applied Roman Numerals (typically set in 18K Yellow Gold) for the hour markers. This choice of markers imparts a classic, timeless, and readable character that provides a powerful contrast to the pristine white field.
