Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278381RBR-0026, cases in steel and gold at 31 mm across. The bezel is diamond-set, and the white mother-of-pearl dial carries diamonds as well, with a Cyclops lens over the date magnifying the calendar window under the sapphire crystal. A self-winding calibre 2236 drives the watch, certified as a chronometer, with a power reserve of about 55 hours. The screw-down crown protects the movement, and central seconds and date round out the functions. Diamonds throughout put this watch firmly among the jewelled Datejust references. The steel and gold bracelet closes with a concealed folding clasp. Water resistance reaches 100 metres, courtesy of the screw-down crown's sealing system.
