Rolex Datejust 31 Yellow Rolesor — Diamond Bezel Olive Green Diamond Roman Six Dial

Among the most distinctive dial configurations in the Datejust 31 portfolio, this Yellow Rolesor example features a diamond-set bezel alongside an olive green dial with diamond hour markers and Roman numeral indices at six o'clock. The olive green colour occupies a narrow band of the chromatic spectrum that reads as sophisticated without veering toward novelty — it is warm enough to harmonise with the yellow gold elements yet sufficiently muted to avoid the showiness of brighter greens. The Roman numeral six, set as a single numeral rather than a full Roman chapter ring, adds a typographic accent that breaks the symmetry of the dial in an intentional, considered way.

Calibre 2236 drives this 31mm Datejust, with its Syloxi silicon hairspring providing the movement's key technical differentiator from earlier Datejust calibres. The hairspring's silicon composition offers inherent resistance to magnetic fields and eliminates the need for lubricants on the escapement, contributing to longer service intervals. The Yellow Rolesor construction — Oystersteel with 18ct yellow gold bezel, crown, and bracelet accents — delivers precious-metal aesthetics at a construction cost lower than full-gold references, with Oystersteel providing the durability advantages of a tool-watch material.

The olive green dial is a recent addition to Rolex's colour palette and enjoys strong current demand, having benefited from the broader collector interest in green dials that has characterised the market since the mid-2010s. This configuration, without a model number suffix in the database, may represent a special-order or regional-distribution variant, which adds an element of scarcity. Buyers drawn to unusual dial colours who also want factory diamond credentials will find this reference a compelling intersection of rarity and refinement.
