Lady-Datejust 26 Black MOP Numerals Dial Fluted Bezel Everose Gold Steel Oyster 179171BMRO

The Rolex Lady-Datejust 26 Ref. 179171 in the BMRO configuration is a rare and striking timepiece from the previous 26 mm generation, expertly blending dark, dramatic elements with the luxurious warmth of Everose Rolesor (Oystersteel and 18K Everose Gold). The watch is framed by the signature 18K Everose Gold Fluted Bezel, a defining Rolex feature that provides brilliant light reflection and contrast. The dial is the centerpiece: a distinctive Black Mother-of-Pearl finish. This unique natural material offers an unusual dark iridescence and shifting color that provides a deep, mysterious backdrop. The dial uses traditional Applied Roman Numerals, typically rendered in 18K Everose Gold, maintaining a classical and highly legible layout against the dark MOP.
