Ref. 278384RBR-0013
Rolex Datejust 31 mm, reference 278384RBR-0013, cased in steel and gold with a 31 mm diameter. The bezel is diamond-set, giving the dial a bright frame against the white lacquered face. A sapphire crystal covers the dial, with the Cyclops lens magnifying the date at three o'clock. Inside is the self-winding calibre 2236, a Rolex manufacture movement with a power reserve of about 55 hours, certified as a chronometer. The screw-down crown protects the movement and helps maintain water resistance. Central seconds and date complete the display. The steel bracelet closes with a folding Oysterclasp fitted with the Easylink comfort extension link, and Rolex rates the case to 100 metres.
