The Rolex Lady-Datejust is one of the most enduring icons in fine watchmaking, and reference 179173-CGDMOPDDO represents the line at its most glamorous. Introduced as the feminine counterpart to the Datejust — itself the world's first self-winding waterproof chronometer wristwatch with an automatic date-changing mechanism — the Lady-Datejust has been gracing the wrists of discerning women since 1957. The 26 mm case size is the traditional, classic expression of this watch, and it remains the benchmark for understated luxury in a ladies' timepiece.

The case and bracelet of reference 179173-CGDMOPDDO are crafted in Rolex's signature Rolesor combination: an Oyster case in corrosion-resistant Oystersteel paired with 18 ct yellow gold appointments. The Oyster case construction — with its patented screw-down Triplock crown — provides meaningful water resistance for a dress watch, giving wearers confidence in daily life. The proportions of the 26 mm case are elegantly compact, sitting close to the wrist with a timeless silhouette that pairs equally well with formal attire and everyday sophistication.

The dial of this reference is what truly sets it apart. The champagne mother-of-pearl surface shifts and shimmers with the light, producing an organic, ever-changing depth that no solid lacquer dial can replicate. Diamond hour markers punctuate this iridescent canvas with precision and brilliance, catching light from every angle and lending the watch the presence of a fine jewel as much as a precision instrument. The yellow gold fluted bezel frames the dial with characteristic Rolex geometry, its machine-cut ridges amplifying reflections and adding textural contrast to the warm gold-and-steel composition.

Powering the 179173-CGDMOPDDO is a Rolex automatic movement, the hallmark of the Datejust family's commitment to self-sufficiency and accuracy. Rolex movements in this reference family are manufactured entirely in-house, regulated to chronometer standards certified by the Swiss Official Chronometer Testing Institute (COSC), and finished to the exacting tolerances for which Geneva's most storied watchmaker is known. The Oyster bracelet, also in two-tone Rolesor, features Rolex's secure clasp system and provides a comfortable, integrated fit that mirrors the refinement of the dial and case above it.

Buying a Rolex Lady-Datejust 26 reference 179173-CGDMOPDDO from Bizak & Co. means acquiring a watch whose combination of champagne MOP, diamonds, fluted yellow gold, and Rolesor construction is extraordinarily difficult to improve upon. This is a watch for a buyer who wants the full expression of Lady-Datejust luxury in its most classic case size. Bizak & Co. is an experienced luxury watch dealer committed to sourcing exceptional timepieces; visit bizakandco.com or contact our team directly to inquire about availability, condition details, and purchase options for this reference.
