About This Watch

The Rolex Datejust 31 278383RBR-0017 marries the enduring elegance of the Datejust collection with a refined interplay of materials and craftsmanship. Its case, a harmonious blend of stainless steel and yellow gold, frames a dial that exudes quiet sophistication—a sunburst-finished grey surface that catches light with subtle depth. Roman numeral indexes, paired with slender stick hands, evoke a timeless aesthetic, while a diamond-set bezel adds a touch of understated opulence. The Oyster case, sealed with a screw-down crown and protected by a sapphire crystal, underscores Rolex’s commitment to durability without compromising refinement.
