Rolex Datejust 31 White Rolesor — Pink Roman Dial, Fluted Bezel | Ref. 278274

Reference 278274 belongs to the current generation of Datejust 31 watches, identified by the 278xxx prefix that signals the fitment of Calibre 2236 — Rolex's most recently developed movement for the mid-size collection. In White Rolesor, the case combines Oystersteel with 18ct white gold across the bezel, crown, and bracelet centre links, creating a cooler, more contemporary aesthetic than the yellow Rolesor alternative. The pink Roman numeral dial adds a softer chromatic register that works in deliberate contrast to the steel and white-gold setting.

Calibre 2236 represents a significant advancement over its predecessor, incorporating a silicon Syloxi hairspring that offers superior isochronism, magnetic resistance, and thermal stability compared to traditional metal hairsprings. Its 55-hour power reserve and Rolex's Paraflex shock protection system place it at the forefront of ladies' and mid-size watchmaking. The fluted bezel in 18ct white gold is finished to Rolex's exacting standards, and the Jubilee bracelet in Rolesor provides an articulated, comfort-oriented fit.

The 278274 in its pink Roman configuration appeals to buyers seeking a modern Datejust with a distinctly feminine yet architecturally refined character. The white Rolesor and pink dial pairing is a considered choice — not a default configuration — that rewards collectors who appreciate deliberate chromatic relationships. As a current-reference watch with 2236 movement technology, it represents the most up-to-date expression of the 31mm Datejust, and examples with box and papers command meaningful premiums in the pre-owned market.
