The Rolex Lady-Datejust 26 Ref. 179160 in the BKRJ configuration is a classic expression of timeless 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, perfectly complementing the stainless steel finish.
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 elegant five-piece link Jubilee bracelet, constructed entirely from Oystersteel. The Jubilee is highly celebrated for its exceptional flexibility, fluid comfort, and classic, dressy appearance on the wrist, fastening securely with the folding Oysterclasp.
