Rolex Datejust 68240 Ladies 31mm Midsize White Date Roman Stainless Steel Oyster

The Rolex Datejust is, without question, the watch that defined the modern dress timepiece. Introduced in 1945 as the first self-winding wristwatch to display the date in a window at 3 o'clock, the Datejust has remained in continuous production through countless references and dial variations, cementing its status as one of the most recognizable luxury watches in the world. The 68240 is the midsize, 31mm iteration of the Datejust family, occupying the sweet spot between the full-sized 36mm and the smaller Lady-Datejust 26mm — a proportion that sits beautifully on a wide range of wrists and has earned a devoted following among both women seeking a refined daily watch and collectors who appreciate the architectural balance of the midsize case.

The case of reference 68240 is crafted entirely in stainless steel — specifically Rolex's proprietary 904L Oystersteel, an alloy prized for its exceptional resistance to corrosion and its ability to take and hold a mirror polish that rivals precious metal. At 31mm in diameter the case is elegantly proportioned without being delicate, and the characteristic Datejust profile — with its flared, stepped lugs and the fluted crown at 3 o'clock — is instantly legible as a Rolex from across a room. The Oyster case construction, featuring a screw-down caseback and a Twinlock crown, ensures robust protection for the movement within.

This particular example is dressed with a white dial bearing Roman numeral hour markers, a pairing that sits at the heart of classic Datejust iconography. The crisp white surface provides maximum contrast for the applied Roman numerals and the date aperture, producing a dial that reads clearly in any light while projecting the kind of quiet, old-world elegance that never dates. The magnified Cyclops lens over the date window — a Rolex trademark since 1953 — amplifies the numeral 2.5 times for effortless legibility. The addition of a custom diamond bezel elevates this reference further, introducing a ring of brilliant-cut diamonds where a standard fluted or smooth bezel would otherwise sit, giving the watch genuine jewelry presence without sacrificing its wearable, tool-watch DNA.

Complementing the case and dial is the stainless steel Oyster bracelet, one of the most enduring and imitated bracelet designs in watchmaking. Its three-piece flat link construction combines comfort, durability, and a versatile aesthetic that pairs equally well with a tailored blazer or weekend casual attire. The Oyster bracelet's deployant clasp ensures a secure, rattle-free fit, and stainless steel resists the stretching and discoloration that can affect lesser bracelet materials over time — an important consideration when purchasing a pre-owned timepiece.

As a used Rolex Datejust 68240 for sale, this watch represents outstanding value in the pre-owned luxury market. The Datejust's combination of timeless design, proven in-house movement technology, and the Rolex name means that well-maintained examples retain their desirability and market value far better than most competing references. The custom diamond bezel adds a layer of personalization that appeals strongly to buyers seeking something beyond stock specification without sacrificing the fundamental Rolex quality and authenticity.
