Rolex Lady-Datejust 31 31 mm 278341RBRSDJ Steel/Rose Gold/Diamonds Silver

The Rolex Lady-Datejust 31 is one of the most enduring icons in Swiss watchmaking—a model that has defined feminine luxury on the wrist since Rolex introduced the Datejust family in 1945, the first self-winding wristwatch to display the date in a window at 3 o'clock. The 31mm case size occupies a beautifully versatile position, larger than the classic 28mm Lady-Datejust yet refined enough to sit elegantly on slender wrists, making it a favorite among collectors who want presence without excess.

Reference 278341RBRSDJ represents a particularly glamorous expression of this storied model. The case and bracelet combine Oystersteel—Rolex's proprietary 904L stainless steel, celebrated for its exceptional corrosion resistance and mirror polish—with 18k Everose gold, the brand's exclusive rose gold alloy formulated to retain its warm blush hue decade after decade without fading. The result is a two-tone aesthetic that feels simultaneously sporty and haute-joaillerie.

The defining visual statement of this reference is its domed bezel set with a continuous pavé of diamonds in 18k Everose gold. Each stone is hand-selected for cut, clarity, and color, then individually set to ensure uniform brilliance around the full circumference of the bezel. Paired with the clean, polished silver dial, the diamond bezel frames the chapter ring with a ring of fire that catches light from every angle without competing with the dial's legibility.

Powering the watch is a Rolex automatic movement, providing the self-winding convenience and precision that collectors expect from Geneva's most recognized manufacture. The Oyster case is rated to 100 meters (330 feet) of water resistance, giving this jewel-set watch a practical robustness that belies its dressy appearance. The five-piece Jubilee bracelet—introduced by Rolex in 1945 alongside the original Datejust—adds a final layer of refinement, its articulated links conforming gracefully to the wrist for all-day comfort.
