Rolex Lady-Datejust 26 26 mm 179173-BLUCAO Steel/Yellow Gold Blue Rolex Lady-Datejust 26 26 mm 179173-BLUCAO Steel/Yellow…

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, having introduced the world's first self-winding waterproof wristwatch with a date aperture scaled expressly for a woman's wrist. Since its debut, the Lady-Datejust has remained a benchmark of Swiss precision and timeless elegance, worn by generations of discerning collectors who demand a watch that performs as beautifully as it looks. Reference 179173 belongs to the 26 mm generation of the Lady-Datejust family, a size that remains the quintessential expression of the line's refined proportions.

The case of reference 179173-BLUCAO measures a classic 26 mm in diameter and is crafted from a combination of Oystersteel and yellow gold—two materials Rolex has long championed together in what the brand calls its Rolesor construction. The yellow gold fluted bezel is one of the most recognizable design signatures in luxury watchmaking, its precise machined grooves catching the light with every movement of the wrist. The Oyster case construction, for which Rolex holds legendary reputation, provides a hermetically sealed environment with water resistance to 100 meters (330 feet), making this watch genuinely capable for everyday life.

The dial of the 179173-BLUCAO is finished in a deep, vivid blue with a concentric-circle texture that adds visual depth and dimensionality without overwhelming the clean legibility of the Arabic numeral hour markers. Blue dials have enjoyed enduring popularity among collectors for their versatility—shifting between navy and sapphire tones depending on the ambient light—and this reference pairs that desirable finish with the warmth of yellow gold accents for a combination that feels simultaneously classic and contemporary.

Powering the watch is a Rolex automatic movement, reflecting the brand's decades of investment in in-house horological engineering. The Oyster bracelet completes the package with its three-piece link construction, engineered for both strength and comfort, and it pairs seamlessly with the two-tone aesthetic of the case and bezel. Together, these elements produce a watch that is as suitable for a business dinner as it is for a weekend brunch.
