Rolex Datejust 31 Yellow Rolesor — White Roman Dial | Ref. 278243

Reference 278243 is the current-generation Datejust 31 in Yellow Rolesor — Rolex's two-tone combination of stainless steel and 18k yellow gold — presented with a clean white dial carrying Roman numeral indices. Within the Datejust lineage, this configuration traces a direct line to some of the most enduring aesthetic choices the model has offered since its 1945 debut, rendered here with contemporary mechanical and finishing standards.

The 278xxx prefix places this reference in the present production series, housing the Calibre 2236 with its Syloxi hairspring, COSC-exceeding chronometric performance, and 55-hour power reserve. Yellow Rolesor construction assigns the crown guards, lugs, and outer bracelet links to 18k yellow gold while the main case and centre bracelet links remain in Oystersteel — a configuration that provides the aesthetic warmth of gold with the structural resilience of steel. The white dial with Roman numerals delivers one of the most legible and classically grounded dial layouts in the Datejust catalogue, avoiding diamond or gem embellishment in favour of clean typographic hierarchy.

For buyers entering the Datejust 31 category, 278243 represents a well-considered choice: current-generation mechanics, a versatile two-tone construction that dresses up or down, and a dial that ages gracefully without relying on fashion-driven elements. It occupies a confident middle ground in the range — more distinctive than plain steel, more restrained than full diamond configurations.
