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

Introduced as part of Rolex's 2020 collection refresh, the Datejust 31 reference 278240 in White Rolesor with a pink dial and domed bezel represents a thoughtful modernisation of the midsize Datejust formula. The pink dial — a warm, feminine hue with applied hour markers in white gold — creates a chromatic softness that contrasts elegantly with the cooler tones of the White Rolesor case construction. The domed bezel, as opposed to a fluted or diamond alternative, keeps the overall profile clean and unencumbered.

Calibre 2236 provides the motive force, a movement Rolex developed specifically for the 31mm and Lady-Datejust family. Its Syloxi hairspring — manufactured in-house from a silicon-based compound — delivers superior antimagnetic performance and contributes to the movement's long-term accuracy stability. A 55-hour power reserve ensures the watch continues running through a full weekend without winding. The Oyster bracelet in Oystersteel with white gold centre links provides both durability and a complementary aesthetic to the case.

Within the Datejust 31 range, the 278240 in Pink Index occupies the entry point of the White Rolesor family, making it one of the more accessible configurations while still offering full manufacture movement credentials. The pink dial has proven popular with buyers who prefer colour without the complexity of diamond-set variants. For collectors entering the Rolex ecosystem at the 31mm size, this reference provides a balanced combination of aesthetics, technical substance, and long-term desirability.
