Rolex Lady-Datejust 26 179163-BLKDO Black Diamond Yellow Gold Stainless Steel Oyster - BRAND NEW

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, representing the first self-winding waterproof watch scaled specifically for the feminine wrist when it was introduced. Across decades of continuous production the Lady-Datejust has remained the definitive expression of Rolex refinement at a compact diameter, and the 26mm case size represented the heart of the collection for generations of collectors and first-time Rolex buyers alike. Reference 179163 sits within the broader Lady-Datejust 26 family and is distinguished by its desirable two-tone configuration, combining polished stainless steel with 18k yellow gold accents across the bezel and bracelet.

The dial of the 179163-BLKDO is where the watch truly commands attention. Rolex designates the BLKDO suffix to indicate a black dial set with factory diamonds, meaning every stone is selected, positioned, and certified by Rolex itself rather than added by a third party. The result is a deep, lustrous black ground punctuated by brilliant-cut diamond hour markers that catch light from every angle, lending the watch a jewellery-level presence without sacrificing legibility. Factory diamond dials carry the full Rolex provenance and add inherent collectibility to any reference.

The yellow gold bezel frames the dial with a polished warmth that accentuates the diamonds beautifully, while the fluted or smooth profile—a hallmark of Rolex craftsmanship—adds dimensional texture that photographs and wears exceptionally well. On the wrist, the two-tone Oyster bracelet in yellow gold and stainless steel is one of the most coveted bracelet configurations Rolex produces, known in collector circles as Rolesor. The interlocking links are machined and finished to exacting tolerances and secured by the Rolex Oysterlock safety clasp for comfortable, confident daily wear.

At 26mm the Lady-Datejust sits with a low, elegant profile that pairs naturally with fine jewelry and formal attire, yet its robust Oyster case construction means it is far more than an occasion watch. The Oyster case has been Rolex's cornerstone architecture since 1926, engineered to protect the movement from dust, pressure, and moisture, making the Lady-Datejust a genuine everyday companion for the discerning wearer. The date function displayed through the iconic Cyclops lens magnifier at three o'clock adds everyday practicality to the watch's undeniable beauty.
