Rolex Datejust 31 Yellow Gold — Olive Green Diamond Dial with Fluted Bezel | Ref. 278278

Olive green has emerged as one of the most discussed dial colours in contemporary Rolex collecting, valued for its earthy, sophisticated tone that occupies a distinct space between the brand's traditional conservative palette and the bolder statement colours introduced in recent catalogue cycles. Reference 278278 brings olive green to the Datejust 31 in yellow gold with a fluted bezel — a combination that pairs the dial's organic warmth with gold's inherent richness and the bezel's machined brilliance in a way that feels both contemporary and historically grounded.

This reference is powered by Calibre 2236, Rolex's current ladies' manufacture movement featuring a Syloxi silicon hairspring that requires no lubrication at the escapement level and provides enhanced magnetic resistance. The 31mm yellow gold Oyster case delivers 100 metres of water resistance, with the fluted bezel machined directly from 18ct yellow gold — a detail that distinguishes solid gold references from Rolesor configurations. Diamond hour markers on the olive green dial are individually set, providing contrast against the muted ground colour and reinforcing the reference's position within Rolex's jewelled-dial tier.

Olive green dial references across Rolex's current lineup have consistently commanded secondary-market premiums, driven by collector demand that frequently outpaces supply. In the context of a 31mm yellow gold Datejust — itself a traditionally strong performer — the olive green diamond configuration represents a rare confluence of colour trend, material quality, and jewel finishing that appeals to both new-generation collectors and established Rolex enthusiasts. The 278xxx generation's improved movement specification further reinforces its long-term collector credentials.
