Rolex Lady-Datejust 26 179173-MOPRDRO White Mother of Pearl Roman Diamond VI Fluted Yellow Gold Stainless Steel Oyster

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced in 1957 as the first self-winding waterproof watch sized specifically for women's wrists. It carried over the same groundbreaking Datejust architecture — the instantly recognizable date window, the Oyster case, and the fluted bezel — into a refined 26mm format that has remained the standard for luxury women's watches for decades. Reference 179173-MOPRDRO represents this legacy in one of its most coveted configurations, blending two-tone materials with a genuinely precious dial surface.

The case of the 179173-MOPRDRO is crafted from Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional resistance to corrosion and its ability to take a brilliant polish. At 26mm in diameter it sits with elegant discretion on the wrist, proportioned perfectly for a dressy everyday companion or a special-occasion timepiece. The Oyster case architecture, with its monobloc middle case and screw-down case back and crown, provides the robust hermetic seal that has always been the foundation of Rolex's reliability promise.

The dial is the undisputed star of this reference. White mother-of-pearl is harvested from the inner lining of mollusks and exhibits a natural iridescent play of color — no two dials are ever quite identical, which gives every watch an inherently personal character. Roman numeral hour markers provide classical legibility against the shimmering surface, while the diamond-set VI index introduces a touch of haute-joaillerie brilliance that elevates the dial from beautiful to extraordinary. Together these elements make the 179173-MOPRDRO one of the most photographed and sought-after Lady-Datejust dial variants on the secondary market.

The 18-carat yellow gold fluted bezel frames the dial with warm, radiant contrast against the Oystersteel case, a pairing Rolex refers to as Rolesor — a tradition dating back to the 1930s that has become synonymous with accessible luxury. The Oyster bracelet follows the same two-tone philosophy, alternating polished yellow gold center links with brushed steel outer links for a supple, wearable result. The concealed Crownclasp allows for a discreet and secure fit while maintaining the bracelet's clean aesthetic lines.

Powering the Lady-Datejust is a Rolex-certified automatic movement, regulated to chronometer standard by the Swiss Official Chronometer Testing Institute (COSC) and then further optimized in-house by Rolex, delivering the precision and long-term reliability the brand is world-famous for. The self-winding rotor means the watch winds continuously through normal wrist movement, requiring no manual intervention for everyday wear.
