Ref. 278343RBR-0023
Rolex's Datejust 31 mm, reference 278343RBR-0023, is a women's model in steel and gold with a 31 mm case. The domed bezel is set with diamonds, and the black mother-of-pearl dial is set with diamonds as well. A Cyclops lens sits over the date on the sapphire crystal. Inside is the self-winding calibre 2236, a chronometer-certified movement with a 55-hour power reserve, shown through central seconds and date functions. The screw-down crown adds to the watch's security. The steel and gold bracelet closes with a folding Oysterclasp fitted with the Easylink comfort extension link. That same clasp helps keep the case sealed to its 100 metre water resistance rating.
