Rolex Lady-Datejust 26 26 mm 179173-BLUDO Steel/Yellow Gold Blue

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, and the 26mm reference 179173-BLUDO represents one of its most captivating expressions. Introduced as the first self-winding waterproof wristwatch designed specifically for women, the Lady-Datejust has graced the wrists of tastemakers, executives, and collectors for decades. With its proportional 26mm Oyster case, it remains the definitive choice for those who want the full prestige of the Datejust lineage in an elegantly scaled format.

The case of reference 179173-BLUDO is crafted in Rolex's proprietary Oystersteel paired with polished 18k yellow gold—a combination Rolex calls Rolesor. This two-tone construction brings warmth and luxury to every angle of the watch, from the polished lugs to the fluted yellow gold bezel that has become synonymous with the Datejust family. The Oyster case is built to Rolex's exacting tolerances, offering a hermetically sealed construction that delivers 100 meters (330 feet) of water resistance.

At the heart of this reference is the stunning blue dial set with diamonds, lending the watch an unambiguous fine-jewelry character. The deep blue hue provides a rich contrast against the warm gold bezel and the steel and gold Oyster bracelet, while the diamond hour markers catch the light with every movement of the wrist. This is a dial designed not merely to tell time but to make a lasting impression.

Powering the watch is an automatic movement, a hallmark of Rolex engineering that ensures precise, self-winding timekeeping without the need for a battery. The Oyster bracelet—featuring Rolex's signature three-piece link architecture in matching steel and yellow gold—secures the watch with the same robust elegance as the case itself, and its folding Crownclasp provides a secure and comfortable fit on even the most active wrist.

For the discerning buyer, the Lady-Datejust 179173-BLUDO represents an intersection of heritage watchmaking and luxury jewelry that very few timepieces can claim. Its 26mm footprint reads as refined rather than understated, and the blue diamond dial elevates it well above a purely functional instrument. Whether you are adding a cornerstone piece to a serious collection or searching for the definitive dress watch to wear daily, this reference delivers on every front.
