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

The Rolex Lady-Datejust is one of the most enduring icons in luxury watchmaking—the first self-winding wristwatch with a date display created specifically for women, introduced by Rolex in 1957 as the feminine counterpart to the legendary Datejust. Across nearly seven decades, the Lady-Datejust has remained the benchmark for elegant, wearable precision, and reference 179174-BLKSBRO represents one of its most striking expressions: a 26mm case in stainless steel paired with 18k white gold appointments, featuring the celebrated black sunbeam dial and Roman numeral indices that give it an unmistakably aristocratic character.

At 26mm, the case diameter of the Lady-Datejust 26 is tailored for the refined proportions of a dress watch. The Oyster case—Rolex's patented hermetically sealed architecture—provides a foundation of robust, scratch-resistant stainless steel, while the 18k white gold fluted bezel elevates the aesthetic into true fine-jewelry territory. The fluted bezel is one of Rolex's most storied design signatures, originally conceived as a functional tightening mechanism and now a symbol of horological heritage and prestige.

The dial of the 179174-BLKSBRO is finished in a black sunbeam texture, a radiating guilloché-style surface that catches and scatters light with hypnotic depth. Roman numeral hour markers reinforce the classical sensibility, lending the dial the gravitas of a timepiece built to be worn at life's most important moments. The overall composition—deep black ground, white gold case metal, and the architectural geometry of the fluted bezel—creates a high-contrast, jewelry-grade aesthetic that photographs brilliantly and commands attention in person.

Power comes from an automatic movement, allowing the watch to wind itself through the natural motion of the wearer's wrist—no battery, no manual winding required in daily wear. The movement is housed within the Oyster case, which is engineered for water resistance to 100 meters (330 feet), making this an exceptionally practical companion despite its dressed-up appearance. The Oyster bracelet, a three-link design iconic to Rolex sport and dress references alike, secures the watch comfortably on the wrist with a polished-and-brushed finish that mirrors the dual-material theme of the case.

For collectors and discerning buyers searching for a Rolex Lady-Datejust 26 for sale, the 179174-BLKSBRO is a particularly covetable reference: the black sunbeam and Roman numeral combination is less common than the champagne or white dials more frequently encountered in this model family, making it a stand-out choice for the buyer who wants a Lady-Datejust that feels distinctive on the wrist. Its two-tone steel and white gold specification keeps it versatile enough to complement white metals and yellow metals in a jewelry wardrobe alike.
