Rolex Datejust 31 mm

This Rolex Datejust 31 mm, reference 278241-0025, has a case in steel and gold measuring 31 mm across. The domed bezel sits above a white mother-of-pearl dial set with diamonds, protected by a sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding chronometer movement with a power reserve of approximately 55 hours. The screw-down crown and central seconds hand accompany a date function with instantaneous change. A folding Oysterclasp with an Easylink comfort extension link closes the steel and gold bracelet, allowing quick adjustment for comfort. The dial's diamonds are set within the mother-of-pearl surface rather than around the case. Water resistance reaches 100 metres, backed by the screw-down crown's Twinlock system.
