Rolex Lady-Datejust 26 26 mm 179174-BLKDO Steel/White Gold Black

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced in 1957 as the first self-winding waterproof watch specifically designed for women at a time when the industry rarely produced such complications at this scale. The Lady-Datejust refined the proportions of the original 1945 Datejust into a 26mm case perfectly suited to the feminine wrist, carrying forward the full Rolex DNA—Oyster case, automatic movement, and date complication—without compromise. Over the decades it has remained a benchmark for elegant everyday luxury, favored by women who demand both precision and style.

Reference 179174-BLKDO represents one of the most glamorous executions of the Lady-Datejust 26 platform. The 26mm case is constructed in a two-tone pairing of polished stainless steel and 18k white gold, a combination that delivers the visual weight of a precious metal watch with the durability and practicality of steel. This blend gives the watch a versatile, luminous quality that transitions effortlessly from boardroom to evening event.

The dial of the 179174-BLKDO is its most commanding feature: a deep black surface set with diamonds that catch light from every angle, creating a constellation-like effect against the dark background. This diamond-set black dial is paired with the unmistakable white gold fluted bezel—a Rolex signature since the earliest Datejust references—whose precisely machined grooves amplify light and frame the dial with architectural elegance. Together, the dial and bezel form a contrast that is both dramatic and refined.

Powering the watch is a Rolex automatic movement, delivering the self-winding reliability and chronometric precision that collectors and everyday wearers alike have trusted for generations. The Oyster bracelet—Rolex's legendary three-link construction—secures the watch with a combination of strength and suppleness, sitting flush against the wrist and complementing the steel-and-white-gold case in both material and tone. The watch also carries a water resistance of 100 meters (330 feet), underscoring its Oyster-case heritage and suitability for active lifestyles.

For a collector or first-time luxury watch buyer, the Lady-Datejust 26 in reference 179174-BLKDO occupies a singular position: it is simultaneously a statement piece and a daily companion, offering Rolex's full horological credibility in a package designed with femininity and artistry at its core. The black diamond dial elevates it above more restrained Lady-Datejust variants, making it the choice for the buyer who wants a watch that is unmistakably present on the wrist.
