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

The Rolex Lady-Datejust is among the most storied and recognizable watches in the brand's catalog, representing decades of horological refinement dedicated specifically to the wrist proportions and sensibilities of women. First introduced in 1957 as a scaled companion to the original Datejust — itself a landmark 1945 creation that was the first wristwatch to display the date in a window on the dial — the Lady-Datejust has grown into an icon in its own right. The 31mm case size occupies a sweet spot between the original 28mm Lady-Datejust and the full-sized 36mm Datejust, appealing to wearers who want presence on the wrist without excess bulk.

Reference 278243OGRDVIO represents one of the most visually compelling configurations in the current Lady-Datejust 31 lineup. The case and bracelet are constructed in a two-tone pairing of Oystersteel — Rolex's proprietary corrosion-resistant steel alloy — and 18-karat yellow gold, a combination the brand calls Rolesor. This marriage of materials has been a Rolex signature since the 1930s and offers the luxurious warmth of gold alongside the durability and everyday practicality of steel.

The green dial is the undisputed focal point of this reference. Rich, deep green has become one of the most sought-after dial colors across the modern Rolex range, evoking the brand's heritage and commanding immediate attention. The yellow gold domed bezel frames the dial with classic elegance, its smooth profile a deliberate choice that keeps the aesthetic refined and timeless rather than sporty. Together, the green dial and gold bezel create a color story that is both bold and deeply wearable.

Powering the watch is a Rolex-certified automatic movement, providing reliable self-winding convenience for daily wear. The case is water resistant to 100 meters (330 feet), a testament to the Oyster case construction that has been a defining Rolex engineering achievement since 1926. The Oyster bracelet — one of Rolex's most celebrated designs — completes the package, offering a secure, comfortable fit that integrates seamlessly with the two-tone case and lug construction.

From a collector and investment standpoint, the Lady-Datejust 31 in two-tone Rolesor with a green dial represents a configuration that enjoys persistent demand. Two-tone Rolex references with distinctive dial colors have historically demonstrated strong value retention in the secondary market, and brand-new, uncirculated examples with no prior ownership command a premium. Whether you are buying the Rolex Lady-Datejust 31 278243OGRDVIO as a personal statement piece, a gift, or a considered addition to a growing collection, this is a reference that rewards the investment.
