Rolex Lady-Datejust 31 31 mm 278288RBRMOP Yellow Gold/Diamonds White Mother of Pearl Rolex Lady-Datejust 31 31 mm 278288RBRMOP Yellow…

The Rolex Lady-Datejust is one of the most enduring icons in fine watchmaking, first introduced in 1957 as the first self-winding, waterproof watch with a date display sized specifically for the female wrist. Over the decades it has evolved in materials, dial artistry, and bracelet design while retaining the instantly legible date window and clean symmetry that made it legendary. Reference 278288RBRMOP represents the line at its most opulent, combining precious metal, gemstone craftsmanship, and Rolex's signature bracelet into one cohesive jewel for the wrist.

The case of the 278288RBRMOP is fashioned entirely in 18k yellow gold — a warm, rich tone that Rolex refers to as Yellow Rolesor in its full-gold expression — measuring 31mm in diameter. At this size the watch sits beautifully on a range of wrist sizes, substantial enough to read confidently as a statement piece yet refined enough to layer effortlessly with bracelets or dress jewelry. The Oyster case's robust construction also provides 100 meters (330 feet) of water resistance, a practical assurance rarely expected in a watch of this jeweled character.

The dial of this reference is set with white mother-of-pearl, a material prized for its organic iridescence and the way it shifts subtly in changing light. No two mother-of-pearl dials are identical, giving each watch a quietly unique character. Framing the case is a bezel set with diamonds, adding a continuous ring of brilliance that elevates the watch from everyday luxury to genuine fine jewelry. Together, the glowing dial and the diamond-set bezel create a synergy that photographs beautifully yet rewards even more in person.

Powering the Lady-Datejust 31 is a Rolex automatic movement, regulated by the brand's Superlative Chronometer standard, which means it has been certified to a precision of plus or minus two seconds per day — a level of accuracy that exceeds the requirements of the Swiss Official Chronometer Testing Institute. The self-winding rotor keeps the movement wound through the natural motion of the wearer's wrist, requiring no battery and minimal intervention beyond regular servicing. This marriage of gem-set aesthetics and serious mechanical performance is the hallmark of the Datejust family.

The President bracelet — developed by Rolex in 1956 and debuted on the Day-Date — is fitted here, lending the 278288RBRMOP a horological pedigree that goes beyond its visual splendor. Its semi-circular three-piece links in 18k yellow gold drape fluidly and wear with extraordinary comfort, secured by Rolex's concealed Crown Clasp for a seamless finish. Owning a Rolex on the President bracelet places the wearer in illustrious company and signals a deep appreciation for the craft.
