Rolex Datejust White Rolesor — Pink Roman Dial | Ref. 278240

Reference 278240 is the Datejust 31 in White Rolesor — Oystersteel combined with 18k white gold — presenting a pink Roman numeral dial that introduces a contemporary warmth against the cooler metal tones. Part of the 278xxx generation launched around 2020, this reference brought the Datejust 31 into the current Calibre 2236 era alongside a reworked case geometry and updated bracelet construction. The pink dial — lacquered to a consistent satin finish — uses applied white gold Roman numerals that provide excellent legibility while contributing a subtle vintage reference in a modern production piece. The domed bezel in white gold frames the dial with clean geometry.

Calibre 2236 provides approximately 55 hours of power reserve and incorporates the Syloxi hairspring — Rolex's proprietary silicon regulating organ that replaces conventional Nivarox alloy springs with a component offering superior magnetic resistance and temperature stability. The Oyster bracelet on the 278240 features Rolex's updated Oysterclasp with the Easylink 5 mm comfort extension, allowing fine adjustment at the clasp. The case, sharing steel and white gold construction throughout its links and integrated bracelet, maintains Rolex's characteristic mix of polished and brushed surfaces.

White Rolesor with a pink dial occupies a sweet spot in the Datejust 31 range: the white gold element elevates the piece above purely steel references while stopping short of the full-gold Lady-Datejust 28 or Pearlmaster configurations. The pink dial has proven particularly popular with buyers who want colour without the bolder statement of turquoise or green variants. As a current-generation reference still available through authorised dealers in limited quantities, pre-owned examples with documentation command healthy demand.
