Rolex Lady-Datejust 26 26 mm 179174-BLUDJ Steel/White Gold Blue Rolex Lady-Datejust 26 26 mm 179174-BLUDJ Steel/White…

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking, representing over seven decades of refined design and mechanical consistency. Introduced as the feminine counterpart to the original Datejust, the Lady-Datejust has carried forward the same core architecture — the Oyster case, the date window, the Cyclops lens — scaled to a 26mm diameter that sits with extraordinary grace on the wrist. Reference 179174-BLUDJ occupies a particularly coveted position within this lineage, pairing two noble materials and a show-stopping dial to produce a watch that reads as both a serious timepiece and a piece of fine jewelry.

At 26mm, the Oystersteel and 18k white gold case of the 179174-BLUDJ is precisely proportioned for a slender wrist. The case middle is crafted in Rolex's proprietary corrosion-resistant steel, while the bezel and crown are rendered in 18k white gold — a material pairing that elevates the watch beyond a standard steel sports model without the full weight of an all-precious-metal piece. The white gold fluted bezel, one of Rolex's most recognizable design signatures, catches light from every angle and frames the dial with architectural precision.

The blue dial on reference 179174-BLUDJ is set with diamonds, adding a layer of brilliance that transforms the dial from a mere timekeeping surface into something closer to a gemstone in its own right. Blue has long been one of the most sought-after dial colors in the Lady-Datejust family — it photographs with depth, complements both yellow and white metal tones, and maintains its vibrancy across different lighting conditions. The diamond hour markers replace printed indices with points of light that animate the dial throughout the day.

Power comes from a Rolex automatic movement, wound by the natural motion of the wearer's wrist through the brand's proprietary rotor system. Rolex automatic movements are renowned for their precision, longevity, and serviceability — qualities that make the Lady-Datejust a watch that can be worn daily and handed down through generations. The movement is water resistant to 100 meters (330 feet), meaning it handles rain, splashing, and everyday moisture with complete confidence.

The Jubilee bracelet completes the 179174-BLUDJ with a five-piece link construction that was originally designed by Rolex to accompany the very first Datejust in 1945. Its tight, intricate links flow with exceptional suppleness across the wrist and are widely considered one of the most comfortable bracelet designs in Swiss watchmaking. On a two-tone steel and white gold model, the Jubilee's polished center links and brushed outer links play beautifully against both materials.
