Rolex Lady-Datejust 31 31 mm 278343RBROGRDVIO Steel/Yellow Gold/Diamonds Green

The Rolex Datejust is one of the most storied timepieces in horological history, introduced in 1945 as the first self-winding wristwatch to display the date in a window on the dial — a milestone that defined the modern dress watch. Across nearly eight decades, the Datejust has evolved in proportion and material while retaining the architectural clarity that made it iconic. The Lady-Datejust 31 occupies a versatile middle ground: larger than the classic 28mm Ladies model yet elegantly scaled for a wide range of wrists, it has become a preferred choice for collectors who want presence without excess.

Reference 278343RBROGRDVIO marries Oystersteel — Rolex's proprietary 904L stainless steel celebrated for its exceptional corrosion resistance and mirror-bright polish — with 18k yellow gold on the case and bracelet center links. This Rolesor combination, a Rolex hallmark since the mid-20th century, gives the watch its distinctive two-tone warmth that works equally well dressed up for an evening out or worn daily with casual attire. The 31mm Oyster case is hermetically sealed and water-resistant to 100 meters (330 feet), making it a genuinely practical luxury companion.

The olive green Roman numeral dial is the centerpiece of this particular reference. Rich, saturated, and subtly complex in different lighting conditions, the olive green hue has emerged as one of the most coveted dial colors in Rolex's contemporary palette. Roman numerals lend a classical gravitas that anchors the dial's design while the green ground gives it unmistakable modernity — a pairing that photographs beautifully and draws the eye in person.

Framing the dial is a yellow gold domed bezel set with a continuous row of diamonds, adding brilliance and luxury that elevate 278343RBROGRDVIO firmly into fine-jewelry territory. The domed profile is one of the most traditional bezel forms in the Datejust family, its graceful curve complementing the fluted case flanks and the polished-and-brushed finish of the integrated Oyster bracelet. The Oyster bracelet itself — with its flat three-piece link architecture and Crownclasp — is among the most comfortable and secure bracelets in fine watchmaking.

At its heart, the Lady-Datejust 31 is driven by an automatic movement, ensuring the watch winds itself through the natural motion of the wearer's wrist and requires no battery. Rolex automatic movements are manufactured to chronometer standards, certified for precision by independent testing, and are a core reason the brand commands the trust of collectors and first-time buyers alike. The combination of technical excellence and extraordinary aesthetics is precisely what makes a Rolex a lifelong investment.
