Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278343RBR-0015, cased in steel and gold, is a chronometer built on a 31 mm frame. The domed bezel is set with diamonds, and the olive green dial carries diamonds of its own, including eleven stones on the large VI marker. A sapphire crystal with a Cyclops lens sits over the date. Inside is the self-winding calibre 2236, a Rolex manufacture movement with a 55-hour power reserve. The screw-down crown adds to the watch's water resistance and protects the movement from moisture. Central seconds and an instantaneous date round out the functions. The steel and gold Oyster bracelet closes with a folding Oysterclasp fitted with an Easylink comfort extension link, and the case is waterproof to 100 metres.
