Rolex Lady-Datejust 31 31 mm 278288RBROGRDVIP Yellow Gold/Diamonds Green

The Rolex Lady-Datejust 31 is one of the most recognizable and celebrated watches in horology, representing the mid-size expression of a collection that Rolex first introduced in 1945 as the world's first self-winding waterproof watch with an automatically changing date. The 31mm case size occupies a versatile sweet spot — substantial enough to wear as a true statement piece yet perfectly proportioned for a wide range of wrist sizes — and reference 278288RBR elevates that classic architecture with an all-precious-metal construction in lustrous 18k yellow gold.

The dial on reference 278288RBR is finished in a captivating olive green, a shade that sits in rare and sophisticated territory between the boldness of emerald and the earthiness of brown-green. Roman numeral hour markers rendered in matching precious metal trace the chapter ring, lending the watch an air of classical elegance that has defined the Datejust aesthetic for generations. The interplay between the warm yellow gold case and bracelet and the cool, organic depth of the olive green dial creates a chromatic tension that is striking in natural light and mesmerizing under candlelight.

The bezel of the 278288RBR is set with Rolex's own factory diamonds, each stone hand-selected and set by Rolex craftspeople to ensure uniform brilliance and flawless alignment around the entire circumference. This diamond-set bezel is not an aftermarket modification but an authentic Rolex factory configuration, which is critical for value retention and integrity. The stones frame the dial without overwhelming it, adding a rim of light that accentuates every glance at the time.

The President bracelet — exclusive to Rolex's precious-metal dress watches — completes the composition with its characteristic three-piece semi-circular links that drape fluidly around the wrist. Originally introduced alongside the Day-Date in 1956, the President bracelet has become synonymous with achievement and refinement, and its presence on the Lady-Datejust 31 elevates the reference into the upper echelon of Rolex's catalog. The concealed Crownclasp on the underside keeps the bracelet's clean lines uninterrupted even at the clasp.

Powering the watch is a Rolex-manufacture automatic movement, delivering the reliable, self-winding performance that Rolex has refined over decades of in-house development. The movement is water-resistant to 100 meters (330 feet) thanks to the Oyster case construction — the Twinlock winding crown and the screw-down case back forming a hermetic seal that protects the movement from moisture and dust in everyday wear.
