Rolex Datejust 79163

Reference 79163 is the smooth-bezel Rolesor model from the 26mm Lady-Datejust 79xxx series, produced from approximately 1999 to 2005. The technical specification ‘Yellow Rolesor’ (3) denotes a bi-metal construction, combining a 904L steel case with solid 18k yellow gold on the winding crown, center bracelet links, and the smooth, polished bezel (16 configuration code). The watch is powered by the Rolex Caliber 2235, a 31-jewel COSC-certified chronometer with a quickset date function. The significance of the Ref. 79163 lies in its status as the modern, understated alternative to the traditional fluted-bezel 79173, offering a contemporary aesthetic while retaining the popular two-tone material combination.
