Rolex Datejust 31 mm

Rolex's Datejust 31 mm, reference 278343RBR-0022, comes in steel and gold with a 31 mm case. The domed bezel is set with diamonds, and a sapphire crystal with a Cyclops lens sits over the date. The dark grey dial is set with diamonds, giving the watch a distinctly dressy presence for a piece this size. Inside is the calibre 2236, a self-winding movement with a 55-hour power reserve and Rolex's Superlative Chronometer certification. Central seconds and a date function round out the display. The steel and gold Jubilee bracelet closes with a concealed folding Crownclasp. The screw-down crown backs up a rating of 100 metres.
