About this watch
This unworn 2020 Rolex Datejust 31 reference 278344RBR presents the collection's most sophisticated interpretation with its white gold case construction and mother-of-pearl diamond dial. The 24mm white gold case strikes an elegant balance between the traditional 26mm and sport-oriented 28mm variants, while the domed diamond bezel adds three-dimensional brilliance that elevates this piece beyond standard fluted bezels. Delivered in pristine condition from its 2020 release year, this Datejust exemplifies Rolex's mastery of precious materials and gemstone setting within their most enduring dress watch platform.
