Rolex Datejust Lady 31 31 mm 278240SVDBO Steel/White Gold/Diamonds Silver

The Rolex Datejust is widely regarded as the archetype of the classic dress watch, and the Lady 31 continues that legacy in a versatile 31mm case size that appeals equally to those seeking a dedicated ladies' watch and those who prefer a refined mid-size wear. Introduced as part of Rolex's ongoing evolution of the Datejust family, the 31mm format occupies a sweet spot between the 28mm Lady-Datejust and the full 36mm case, offering greater dial legibility without sacrificing elegance. Reference 278240SVDBO represents a particularly desirable configuration within this line.

The case and bracelet of the 278240SVDBO are constructed from Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and high-polish lustre — complemented by white gold accents that elevate the aesthetic into true luxury territory. The Oyster bracelet, one of Rolex's most iconic and enduring designs, provides a secure and comfortable fit on the wrist while maintaining a dressy profile suited to both formal occasions and sophisticated daily wear.

The dial is finished in silver, a timeless choice that catches the light with a clean, luminous quality and reads effortlessly against the diamond-set bezel surrounding it. The custom diamond bezel is the defining visual statement of this reference: individually set stones encircle the case, adding a layer of brilliance and exclusivity that distinguishes this configuration from the standard fluted or smooth bezel variants. The combination of silver dial and diamond bezel creates a cohesive, high-jewelry aesthetic without veering into excess.

At the heart of the watch is a Rolex automatic movement, the hallmark of the brand's commitment to precision and self-sufficiency. The Oyster case provides water resistance to 100 meters (330 feet), ensuring that this watch is not merely decorative but genuinely robust and wearable in everyday situations. The screw-down Oyster crown, a Rolex innovation dating back decades, seals the case hermetically and contributes to the watch's proven durability.

The Rolex Datejust Lady 31 278240SVDBO is an ideal choice for the discerning buyer who wants an iconic Swiss manufacture watch with elevated diamond detailing, mid-size wearability, and the enduring prestige of the Datejust name.
