Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278384RBR-0034, is a women's model in steel and gold measuring 31 mm across. The case is fitted with a diamond-set bezel and holds a silver dial set with diamonds, viewed through a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding movement with Rolex's own chronometer certification and a power reserve of about 55 hours. The screw-down crown protects the movement and adds to the watch's overall solidity. Functions are kept simple, with central seconds and a date display. A steel bracelet with a concealed folding Crownclasp completes the watch. Water resistance stands at 100 metres, backed by the screw-down crown's double waterproofness system.
