Rolex Datejust 31 mm

This Rolex Datejust 31 mm, reference 278341RBR-0010, comes in a steel and gold case measuring 31 mm across. The domed bezel is set with diamonds, and the sunray rosé dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a perpetual, self-winding movement with a power reserve of approximately 55 hours and Rolex's chronometer certification. The screw-down crown adds central seconds and an instantaneous date to the display. Diamonds also appear elsewhere on the case, giving the watch a jewellery-like finish. A Jubilee bracelet in matching steel and gold closes with a concealed folding Crownclasp. The case is rated to 100 metres of water resistance.
