Start with the dial. Chocolate is one of Rolex’s warmer, less common dial colors, and it behaves differently depending on the light hitting it, sometimes reading almost black, other times opening up into a lighter caramel brown. Set into that dial are diamond hour markers applied by Rolex at the factory, not added by a third party after the fact. That distinction matters enormously, both for how the watch is valued and for how easily it can be verified as genuine down the line.
The case and bracelet use Rolex’s Rolesor construction, steel through the body of the case and the outer bracelet links, Everose gold on the fluted bezel, the crown, and the center bracelet row. Rolex has used this two metal approach since the 1930s, and it remains one of the most requested combinations across their entire current lineup because it offers the look of gold without the full weight or cost of a solid gold piece.
The bracelet itself is the Jubilee, which actually debuted alongside the original Datejust back in 1945 to mark the watch’s launch. Its five link design gives it a noticeably softer drape on the wrist compared to a plain link Oyster bracelet, and against the alternating steel and Everose case, the Jubilee bracelet’s own mix of polished and brushed links pulls the whole watch together visually.
Inside, reference 278271 is powered by the Rolex Caliber 2236, a manufacture movement with a power reserve of roughly 55 hours and the kind of day to day accuracy Rolex chronometers are built around.
