Rolex Lady-Datejust 31 31 mm 278271SSJ Steel/Rose Gold Slate

The Rolex Lady-Datejust has been the defining expression of feminine watchmaking elegance since Rolex introduced the Datejust family in 1945—the first self-winding wristwatch to display the date in a magnified window on the dial. Over decades of refinement, the Lady-Datejust evolved into its own distinguished line, and the 31mm case size occupies the sweet spot between the compact 28mm and the full-sized 36mm, offering generous dial legibility without sacrificing the refined silhouette the line is known for. Reference 278271SSJ represents the current generation of this icon, combining the enduring design vocabulary of the Datejust with modern Rolex materials and finishing standards.

The 31mm Oyster case of the 278271SSJ is constructed in Oystersteel—Rolex's proprietary 904L stainless steel alloy celebrated for its exceptional corrosion resistance and ability to hold a mirror polish over years of wear—complemented by 18k Everose gold components that bring warmth and luxury to the profile. Everose gold is Rolex's exclusive rose gold alloy, engineered in-house to resist fading over time, ensuring the blush tones remain vibrant throughout the life of the watch. The screw-down Oyster crown and robust case construction contribute to the 100-meter (330-foot) water resistance rating, making this a genuinely versatile daily companion.

The slate dial is one of the most coveted color choices in the Lady-Datejust 31 lineup, prized for its rich, neutral depth that transitions between warm and cool lighting conditions with remarkable elegance. Index hour markers—polished to catch the light—sit cleanly against the dark ground, ensuring legibility without cluttering the dial's calm, sophisticated aesthetic. The cyclops lens positioned over the date window at 3 o'clock magnifies the date 2.5x, a hallmark Datejust detail that remains as functional as it is iconic.

Framing the dial is an 18k Everose gold fluted bezel, one of the most recognized design signatures in watchmaking. The geometric fluting was originally engineered to reinforce the bezel and has since become a symbol of Rolex horological heritage. Paired with the five-piece link Jubilee bracelet—another invention by Rolex, introduced alongside the original Datejust in 1945—the overall presentation is one of graceful symmetry: the warmth of rose gold bookending the cool steel and the serene slate center. The Jubilee bracelet's fine links flex elegantly on the wrist and are equipped with Rolex's concealed Crownclasp for a clean, uninterrupted profile.

At the heart of the 278271SSJ beats a Rolex automatic movement, providing the self-winding convenience expected of a modern Rolex with the reliability that the brand has built over a century of manufacture. Rolex movements are produced entirely in-house and are certified as Superlative Chronometers, held to accuracy standards that exceed the official COSC chronometer certification. This means the watch can be relied upon not only as a luxury accessory but as a precise daily instrument.
