Rolex Datejust 31mm Dark Grey 10 Diamonds Jubilee 278274

Overview 

The 278274 applies the Datejust 31's White Rolesor construction — Oystersteel case with 18-carat white gold fluted bezel — to a dark grey dial set with ten diamond hour markers. The combination is contrast-driven: the grey absorbs light while the white gold and diamonds reflect it. At 31mm, this sits in the mid-size bracket of the current Datejust range, between the 28mm and the 36mm, which positions it across a wider range of wrist sizes without the watch reading as either compact or oversized.

The case is 31mm Oystersteel with a fluted 18-carat white gold bezel. The dark grey dial carries ten brilliant-cut diamond hour markers in place of standard applied indices — a Rolex production configuration, not an aftermarket modification. The Jubilee bracelet is the five-link construction; on the White Rolesor, the centre links are 18-carat white gold, extending the two-material construction from the bezel into the bracelet. Cyclops lens at 3 o'clock; date complication.

The Calibre 2236 powers the 31mm Datejust — Rolex's dedicated movement for this case size, running a Syloxi silicon hairspring rather than the Parachrom found in the larger calibres. Power reserve is 55 hours. Certified Superlative Chronometer to ±2 seconds per day. Water resistance is 100 metres.

Within the 278274 range, diamond dial configurations occupy a distinct tier — Rolex factory-sets the stones as part of the production run, which limits supply relative to the standard index configurations. The dark grey is the more wearable choice against diamond markers: it creates enough contrast for the stones to read clearly across different lighting conditions, whereas white or silver dials compress that distinction. Brand new, unworn, complete with box and papers dated May 2026, at RM66,500.
