Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278241-0001, comes in steel and gold with a 31 mm case. The domed bezel sits above a white dial, and the date window carries the Cyclops lens set into a scratch-resistant sapphire crystal. Inside is the self-winding calibre 2236, a chronometer-certified movement with central seconds and a date function. A screw-down crown protects the movement from moisture. The steel and gold bracelet closes with a folding Oysterclasp fitted with an Easylink comfort extension link, allowing small adjustments on the wrist. This is a dress watch built for daily wear, and Rolex rates the case to 100 metres of water resistance.
