Rolex Datejust 31 White Rolesor — Mint Green Index Dial | Ref. 278384RBR

Reference 278384RBR brings together White Rolesor construction — Oystersteel with 18 ct white gold bezel, crown, and bracelet centre links — with one of the most visually striking dial options in the current Datejust 31 lineup: a mint green ground set with diamond index markers and enclosed by a diamond-set bezel in the RBR configuration. Mint green dials gained significant collector attention in recent seasons and have become emblematic of Rolex's willingness to push past conventional conservative dial palettes without sacrificing the restraint that defines the Datejust aesthetic. The cool green harmonises naturally with white gold, creating a cohesive ice-toned presentation.

Calibre 2236 is fitted within the 31 mm Oyster case, its Syloxi hairspring and 55-hour power reserve making it one of the most technically refined movements available in a watch of this size class. The movement's construction reflects decades of Rolex experience in developing mid-size and ladies' calibres that meet the same performance standards as their full-size counterparts. The Jubilee bracelet in White Rolesor — alternating steel and white gold links — extends the two-tone theme from dial to wrist, lending the piece a cohesive luxury character.

Collectors tracking the Datejust 31 market will note that mint green dial references have demonstrated strong secondary market performance since their introduction, driven by sustained demand among buyers who want a contemporary colour statement within an enduring classic format. The addition of a diamond bezel elevates the reference into a segment where supply is perennially constrained. Whether acquired as a primary wearable timepiece or as part of a broader Datejust colour-study collection, the 278384RBR represents a configuration with clear appeal and demonstrable hold on desirability.
