The Rolex Lady-Datejust 26 Ref. 179160 in the BLAO configuration is a classic expression of elegance and reliable watchmaking, distinguished by its traditional 26mm size and durable monobloc construction entirely in Oystersteel (Stainless Steel). This reference features the all-steel aesthetic with a signature Smooth/Domed Bezel, polished to a high sheen, which provides a clean, understated, and versatile look.
The watch’s profile is the enduring classic of the Lady-Datejust line. The Smooth Bezel offers a contemporary, clean frame. Securing the watch to the wrist is the robust, three-piece link Oyster bracelet, constructed entirely from Oystersteel. The Oyster bracelet is celebrated for its strong, refined architecture and classic profile, offering a perfect balance of durability and style, and fastening securely with the folding Oysterclasp.
