Rolex Datejust Lady 31 31 mm 278240WRDVIDBO Steel/White Gold/Diamonds White Mother of Pearl Rolex Datejust Lady 31 31 mm 278240WRDVIDBO…

The Rolex Datejust is widely regarded as the archetype of the classic dress watch, introduced by Rolex as the first self-winding wristwatch to display the date in a window on the dial. Across its many decades in production, the Datejust family has been refined into distinct size expressions, and the Lady 31 occupies the sweet spot between the traditional ladies 28 mm and the full 36 mm Datejust—making it one of the most versatile and sought-after references in the entire catalogue. Reference 278240WRDVIDBO carries that storied lineage forward with an elevated set of specifications that appeal to collectors and first-time luxury buyers alike.

The 31 mm Oyster case of this Datejust is constructed in stainless steel paired with white gold accents, a combination Rolex refers to as Rolesor, giving the watch a two-tone brilliance that reads as simultaneously sporty and refined. The custom diamond bezel replaces the standard fluted or smooth option with an array of brilliant-cut diamonds set around the full circumference of the bezel, catching the light from every angle and lending the piece unmistakable jewellery-grade presence. The integration of white gold in the construction ensures that the setting metal for the diamonds is both precious and durable.

At the centre of attention is the white mother-of-pearl dial, a material prized for its organic luminosity and the way it shifts subtly in different lighting conditions. The Roman numeral VI index is set with diamonds, creating a focal point that draws the eye and underscores the gem-set character of the watch without overwhelming the clean symmetry of the Datejust layout. The remaining hour markers and the date window at three o'clock preserve the legibility and balance that have defined the Datejust aesthetic for generations.

Powering the watch is an automatic movement, meaning the rotor harvests energy from the natural motion of the wearer's wrist and winds the mainspring continuously—no battery is ever required. Rolex's in-house movements are celebrated for their precision, reliability, and longevity, and this reference benefits from that engineering heritage entirely. The watch also carries a water resistance rating of 100 metres, courtesy of the Oyster case's screw-down crown and case-back construction, making it practical for everyday wear well beyond ceremonial occasions.

The Oyster bracelet completes the watch with a three-link design that is both robust and comfortable, tapering elegantly toward the clasp. Its polished and satin-finished surfaces mirror the mixed-metal theme of the case, and the bracelet's engineering ensures a secure, rattle-free fit on the wrist. Together with the 31 mm case diameter, the overall package sits proportionally on a wide range of wrist sizes, making this one of the more universally flattering configurations Rolex offers.
