About This Watch
Reference 278384RBR is among the more vivid contemporary expressions of the Datejust 31 — a White Rolesor (Oystersteel and 18ct white gold) case set with a diamond bezel and dressed with a mint green dial bearing applied index markers and diamond hour positions. The 'RBR' suffix denotes a full diamond-set bezel with brilliant-cut stones, adding a ring of brilliance that frames the unusual dial colour effectively. Mint green has emerged as one of the standout dial shades in Rolex's current palette, appealing particularly to younger collectors drawn to contemporary colour choices.
Calibre 2236 is the movement of choice for 31mm Datejust references, providing a 55-hour power reserve and the reliability of Rolex's Syloxi silicon hairspring technology. White Rolesor construction — alternating polished Oystersteel and white gold on the case, bezel, and bracelet — keeps the overall palette cool and cohesive, allowing the mint green dial to take centre stage. Water resistance to 100 metres is standard across the Datejust Oyster case family, an underappreciated practical benefit in a watch that commands everyday wear.
Mint green dial references in the current Datejust generation have developed a loyal following among collectors who value differentiation from the more conventional blue, black, and white options. Diamond-bezelled variants tend to sell more quickly in the secondary market than plain-bezel counterparts, reflecting demand from buyers who want both horological provenance and jewellery character. Immaculate examples with full documentation are scarcely available given the number that enter daily circulation — pristine White Rolesor 278384RBR pieces are more elusive than production volumes alone would suggest.
