Rolex Datejust 31 White Rolesor — Silver Index Dial Jubilee | Ref. 278240

Released in 2020 as part of Rolex's comprehensive Datejust refresh, reference 278240 introduced white Rolesor to the mid-size 31mm format — combining Oystersteel with 18ct white gold on the bezel and crown. The result is a Datejust that occupies the same chromatic register as a steel watch while signalling precious metal through the touch points of bezel and crown. White gold and steel share a cool, silver-adjacent palette that creates a highly coherent monochromatic aesthetic quite distinct from the warmer two-tone combinations.

The silver index dial is the most fundamentally practical Datejust configuration: clean, precise, and legible in any light, with applied white gold indices providing clear hour marking without distraction. The domed bezel in white gold adds the characteristic Datejust profile — its slight outward curve providing both visual definition and the tactile sensation of quality manufacturing. Calibre 2235, Rolex's dedicated mid-size movement, powers this reference with the reliability appropriate to a watch worn daily.

On the Jubilee bracelet in mixed steel and white gold centrelinks, this current-generation 278240 is a genuinely versatile watch: professional enough for office environments, refined enough for formal occasions, and robust enough for everyday wear. The 31mm case size suits a wide range of wrist measurements and translates across genders. A current-generation Datejust built for people who want quality without ostentation.
