Rolex Datejust 31mm Mint Green Jubilee 278240

Overview

Within the all-Oystersteel Datejust 31 configurations, the dial colour does most of the positioning work. The 278240 in mint green with Jubilee bracelet makes a specific case: it takes the same case and bezel as the most pared-back Datejust 31 in the lineup and gives it a dial that reads as contemporary rather than classical. The smooth bezel and all-steel construction keep the material story simple; the mint green provides the only visual departure from the monochromatic.

The case is Oystersteel, 31mm, with a smooth domed bezel. The Jubilee bracelet in Oystersteel, five-piece links, is the historically correct Datejust pairing, and on the smooth bezel all-steel configuration it softens the watch's character relative to the Oyster bracelet variant of the same reference. The dial is mint green with applied baton hour markers and polished hands; the colour sits in a cooler register than champagne or cream, and warmer than a pure silver or white. The Cyclops lens magnifies the date at 3 o'clock.

The movement is Calibre 2236, Rolex's mid-size automatic developed specifically for the 31mm Datejust. It carries a Syloxi silicon hairspring, delivers a 55-hour power reserve, and is certified as a Superlative Chronometer to within ±2 seconds per day.

The 278240 in mint green on Jubilee occupies a specific point within the all-steel Datejust 31 range: same case and bezel as the grey or silver index variants, different dial character and bracelet register. Against the diamond-set and Rolesor configurations in the wider 278xxx lineup, the all-steel smooth bezel Jubilee is the most accessible entry by price. We are currently seeing all-steel Datejust 31 examples trade around this price tier; this piece at RM41,000 reflects new the sought-after dial and a brand-new complete-set configuration. Brand new, unworn, complete with original box and papers dated June 2026, at RM41,000.
