Rolex Lady-Datejust 28 28 mm 279173SSO Steel/Yellow Gold Silver Rolex Lady-Datejust 28 28 mm 279173SSO Steel/Yellow…

The Rolex Lady-Datejust 28 is the definitive expression of feminine luxury watchmaking, and reference 279173SSO represents that ideal in its most classic form. Introduced as an evolution of the historic Lady-Datejust line, the 28mm case size strikes a precise balance: substantial enough to read beautifully on the wrist, refined enough to wear beneath a cuffed sleeve or alongside the most delicate jewelry.

The case of reference 279173SSO is rendered in what Rolex calls Rolesor—a signature two-tone construction pairing Oystersteel, Rolex's proprietary corrosion-resistant steel alloy, with 18k yellow gold. The fluted bezel is crafted entirely in 18k yellow gold, its vertically grooved surface catching light with every movement of the wrist and providing a warm, luminous frame for the dial. This bezel profile is one of the most historically significant in watchmaking, originally conceived as a functional feature to screw the bezel to the case and later elevated into a defining aesthetic icon.

The silver dial of the 279173SSO is understated and authoritative. Clean index hour markers—polished to reflect light precisely—sit against the smooth silver surface, lending the watch a sense of quiet confidence that suits both boardroom and black-tie occasions. The Datejust's signature date window, framed by a magnifying Cyclops lens on the crystal, appears at the three o'clock position, grounding the design with the utilitarian precision that has made the Datejust the world's best-recognized watch.

Rolex specifies self-winding calibre 2236 for reference 279173. The two-tone Oyster bracelet uses a folding Oysterclasp.
