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

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced in 1957 as the first self-winding waterproof wristwatch sized specifically for women. Over the decades it has evolved into a canvas for extraordinary materials and gem-setting, and the 31 mm case size — positioned between the 28 mm Lady-Datejust and the full 36 mm Datejust — has become a favorite for those who appreciate a slightly bolder statement without sacrificing femininity. Reference 278288RBR represents this lineage at its most opulent, combining 18k yellow gold construction with diamond ornamentation across the bezel.

The case and bracelet of the 278288RBR are crafted entirely in 18k yellow gold, Rolex's hallmark Oystersteel-free precious-metal expression that radiates warmth under any light. The 31 mm Oyster case is characteristically robust, with polished and brushed surfaces that catch the light from every angle. Yellow gold has long been synonymous with the Datejust family, and on this reference the choice of metal elevates the watch from a daily timepiece to a genuine jewel for the wrist.

The bezel is set with a continuous ring of round brilliant diamonds, transforming the watch's profile into something closer to fine jewelry than traditional horology. Rolex's in-house gem-setters select and place each stone individually to ensure uniformity of color, cut, and brilliance. Below the bezel, the silver dial is appointed with Roman numeral hour markers, a detail that reinforces the watch's classical character and provides high legibility against the bright dial surface. The interplay between the warm yellow gold case, the sparkling diamond bezel, and the clean silver Roman dial is immediately distinctive.

Powering the Lady-Datejust 31 is a Rolex-certified automatic movement, representative of the brand's commitment to precision and reliability in every reference it produces. Rolex movements are manufactured to COSC chronometer standards and beyond, regulated and certified in-house to stricter tolerances than the industry norm. The result is a timepiece that functions as accurately as it looks beautiful, requiring no manual winding during regular wear thanks to the perpetual rotor system.

The President bracelet completes the watch and may be its most storied element. Originally introduced in 1956 on the Day-Date, the three-piece semi-circular link bracelet has come to symbolize prestige and achievement; wearing it signals an understanding of Rolex's hierarchy of materials and craft. On the 278288RBR the bracelet is rendered in full 18k yellow gold, flowing seamlessly from the lugs and secured with a concealed Crownclasp for a refined finish.
