Rolex Datejust 31 White Rolesor — Fluted Bezel Mint Green Index Dial | Ref. 278274

Mint green is among the most sought-after dial colours to emerge from Rolex's recent palette expansions, and Reference 278274 deploys it to striking effect on the Datejust 31 in White Rolesor. The cool, almost glacial green of the dial sits against the bright, architecturally fluted white gold bezel and Oystersteel case with a freshness that marks this configuration as distinctly contemporary while remaining anchored to the Datejust's eight-decade aesthetic lineage.

Calibre 2236 — Rolex's in-house movement purpose-built for the 31 mm Datejust — brings its full technical complement to the 278274. The Syloxi silicon hairspring, introduced in this calibre, provides antimagnetic performance that surpasses traditional metal alloys, while the bidirectional Perpetual rotor ensures efficient winding from natural wrist movement alone. COSC chronometer certification is the foundation; Rolex's own subsequent regulation refines performance further, targeting accuracy of +2/−2 seconds per day. Water resistance reaches 100 metres courtesy of the Oyster case's screw-down Twinlock crown.

The index dial in mint green represents a collector's opportunity to own a colour that generates consistent market attention. White Rolesor amplifies the freshness of the palette: the combination of brushed Oystersteel and polished white gold never overwhelms the dial's subtle tones. For collectors assembling a diverse Datejust portfolio, or for those seeking a single statement piece with broad seasonal versatility, the 278274 in mint green delivers precisely the distinction that differentiates a considered collection from a merely complete one.
