Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278343RBR-0029, measures 31 mm across in steel and gold. The domed bezel is set with diamonds, and the olive green dial is likewise set with diamonds, viewed through a sapphire crystal with a Cyclops lens over the date. Inside is calibre 2236, a self-winding chronometer movement with a 55-hour power reserve. Rolex includes central seconds and date functions, and the crown screws down against the case. The steel and gold bracelet closes with a folding Oysterclasp fitted with the Easylink comfort extension link, which lets the wearer lengthen the bracelet slightly for a better fit. As a women's watch set with diamonds rather than a tool piece, it still carries a 100 metre water resistance rating from Rolex.
