Rolex Lady-Datejust 31 31 mm 278288RBRSDP Yellow Gold/Diamonds Silver

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, tracing its origins to 1957 as the first self-winding, waterproof, date-displaying wristwatch sized specifically for women. Over the decades it has become synonymous with refined achievement, worn by world leaders, artists, and tastemakers who demand both function and impeccable style. The 31mm case size — introduced to bridge the classic 26mm Ladies and the 36mm full-size Datejust — offers a versatile, contemporary fit that reads as purposeful and modern on virtually every wrist.

Reference 278288RBRSDP is built on a 31mm case and bracelet crafted entirely in 18k yellow gold, a material Rolex produces in its own foundry to exacting standards of purity and consistency. The warm, rich tone of yellow gold gives this reference a decidedly glamorous character, one that aligns perfectly with the President bracelet — a three-piece link design originally created in 1956 as Rolex's most prestigious bracelet and offered exclusively on Lady-Datejust and Day-Date models. Together, the yellow gold case and President bracelet form a seamless, sculpted silhouette that drapes the wrist with understated weight and luxury.

The factory diamond-set bezel is among the most covetable elements of this reference. Rolex's gem-setting artisans individually select, cut, and set each diamond to maximize brilliance and ensure perfectly matched color and clarity, transforming the bezel into a continuous arc of light that catches every angle of illumination. Paired against the cool, polished silver dial, the diamonds create a striking contrast — warm gold, icy sparkle, and a serene dial surface that keeps the date display legible and the overall presentation uncluttered.

Powering the Lady-Datejust 31 is a Rolex-certified automatic movement, a self-winding mechanical caliber that reflects decades of in-house research and development. Rolex movements undergo the brand's stringent Superlative Chronometer testing — a proprietary standard that goes beyond COSC certification — ensuring precision, reliability, and consistency in daily wear. The movement winds continuously via a Perpetual rotor, meaning the watch maintains its power reserve through the natural motion of the wearer's wrist.
