Rolex Lady-Datejust 31 31 mm 278243OGRDVIJ Steel/Yellow Gold Green

The Rolex Lady-Datejust is one of the most enduring icons in fine watchmaking, having defined what a luxury dress watch for women could look like since its introduction in 1957 as the first self-winding waterproof watch scaled specifically for the female wrist. Across decades it has remained the reference point against which other watches in its category are measured, and the current 31mm generation—represented here by reference 278243OGRDVIJ—distills everything that made the original compelling while adding the refinement and material quality of contemporary Rolex manufacture.

At 31mm the case occupies a sweet spot between the slender 28mm Lady-Datejust and the full-size 36mm Datejust, offering a diameter that sits gracefully on a range of wrist sizes without sacrificing legibility or presence. The case and bracelet are constructed in a two-tone combination of Oystersteel—Rolex's proprietary corrosion-resistant steel alloy—and yellow gold, a pairing that instantly signals luxury without the full weight of an all-gold watch. The yellow gold domed bezel traces a clean, rounded arc that focuses the eye squarely on the dial.

The green dial of this 278243OGRDVIJ is the defining visual statement of the piece. Green has emerged as one of Rolex's most celebrated dial colors, projecting an air of confident individuality that complements the warmth of yellow gold in a way few other hues can. The Jubilee bracelet—a five-piece link design created by Rolex in 1945 specifically to accompany the original Datejust—echoes that blend of steel and gold across the wrist and provides the supple, fluid drape that makes the watch feel as comfortable as it looks refined.

Power comes from an automatic movement, and the watch carries a water resistance rating of 100 meters (330 feet), underscoring that this is a genuine Rolex tool watch at heart, not merely a jewel for special occasions. The Oyster case construction, the screw-down crown, and that water resistance figure mean the Lady-Datejust 31 can accompany its wearer through daily life without reservation, from morning to evening, from the office to the pool deck.
