Rolex Datejust 31 Yellow Gold — Malachite Diamond Dial, Six & Nine | Ref. 278288RBR

Malachite is among the most visually arresting dial materials Rolex deploys — the stone's natural banding creates an organic pattern that no two dials replicate exactly, making each watch genuinely unique at the dial level. On this Datejust 31 in yellow gold, a malachite dial is set with diamond hour markers and distinctive six and nine numeral indicators, a mixed-indexing approach that adds a jewellery character while maintaining dial legibility. The diamond bezel surrounding the 31mm case completes an ensemble that operates in the territory of high gem-set watchmaking as much as traditional horology.

The President bracelet and yellow gold case construction place this in the top specification tier of the Datejust 31 range. Calibre 2236 provides the movement, its silicon Syloxi hairspring delivering a 55-hour power reserve with excellent magnetic resistance. Superlative Chronometer certification ensures precision to ±2 seconds per day in the finished piece. The President bracelet — traditionally associated with the Day-Date — brings a semi-circular three-link aesthetic in solid 18-carat yellow gold, fully integrated with the case for a seamless silhouette.

Malachite dials represent a meaningful collector proposition: they combine the organic uniqueness of a natural stone with Rolex's gem-setting precision, and the green tones of malachite have attracted substantial collector interest as green dials broadly appreciate in the market. The six and nine numeral detail adds a differentiated indexing character that distinguishes this configuration from standard all-index Datejust variants. Yellow gold amplifies the warmth of the green stone, creating a pairing that feels intentionally composed. For collectors focused on exceptional dial materials, malachite Datejusts consistently command premium attention.
