Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278274-0022, is a women's watch in steel and gold measuring 31 mm across. The case carries a fluted bezel in gold and the dark grey dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding mechanical movement with a power reserve of approximately 55 hours, and Rolex certifies the watch as a chronometer. The screw-down crown and monobloc case work together with the movement's construction to protect the going train. Functions include a central seconds hand and an instantaneous date display.
