About This Watch

The Rolex Datejust 31, in its 278289RBR-0023 iteration, exemplifies the enduring balance of refinement and precision that has defined the collection since its introduction in 1945. This particular model distinguishes itself through a striking combination of materials and design: a 31-millimeter white gold case encircles a dial of deep, rich blue, its sunburst finish catching light with subtle, shifting depth. The bezel, adorned with meticulously set gemstones, adds a touch of opulence without overwhelming the watch’s classic silhouette, while Roman numeral indexes and slender stick hands reinforce its timeless aesthetic. The Datejust’s heritage as a symbol of understated elegance is evident here, with every detail—from the polished lugs to the closed case back—emphasizing craftsmanship honed over decades. At its core, the watch is driven by Rolex’s in-house Caliber 223
