Rolex Datejust 31 mm

The Rolex Datejust 31, reference 278274-0020, measures 31 mm across in steel and gold. A fluted gold bezel and a screw-down winding crown finish the case, and the pink dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding movement with a 55-hour power reserve. Rolex certifies the watch as a chronometer. Central seconds run alongside the date function, both driven by the same movement. A five-piece Jubilee bracelet in steel closes with a concealed folding Crownclasp in steel and gold. That same screw-down crown keeps the case sealed to 100 metres.
