Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278243-0029, is a women's watch case in steel and gold measuring 31 mm across. The domed bezel sits above an olive green dial set with diamonds, and a sapphire crystal with a Cyclops lens over the date covers the face. Inside is calibre 2236, a self-winding chronometer movement with a power reserve of approximately 55 hours. Central seconds and a date function round out the display, and the screw-down crown adds a further layer of protection. A steel and gold bracelet closes with a folding Oysterclasp fitted with the Easylink comfort extension link. The clasp is part of a case built to withstand pressure to 100 metres.
