Lady-Datejust 26 Mother-of-Pearl 10 Diamond Dial 18K Yellow Gold Steel Jubilee 179173MDJ

The Rolex Lady-Datejust 26 Ref. 179173 in the MDJ configuration is an intensely luxurious and unique timepiece from the previous 26 mm generation, celebrated for its use of the beautiful and dynamic Mother-of-Pearl. This model is constructed using the iconic two-tone aesthetic, 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 absolute centerpiece of this timepiece is the exquisite Mother-of-Pearl (MOP) Diamond Dial . Sliced from the inner shell of an oyster, MOP is treasured for its natural iridescence, shimmering through a spectrum of colors—from white and pink to soft blue—that shift constantly with the light. Because no two slices are exactly alike, this dial grants the watch a truly unique, organic character. Adorning this mesmerizing, natural surface are sparkling 10 Diamond Hour Markers (brilliant-cut stones), which are elegantly set in 18K Yellow Gold, ensuring superb clarity and maximum brilliance against the ethereal MOP backdrop.
