Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278274-0013, has a case in steel and gold measuring 31 mm across. The bezel is fluted, a signature Rolex touch on this size of Datejust. Inside is the calibre 2236, a self-winding movement with a 55-hour power reserve and Rolex's own chronometer certification. A sapphire crystal with a Cyclops lens sits over the date, and the pink dial carries luminous hands and indices for legibility. The watch also has a central seconds function alongside the date, and the crown is a screw-down type. It comes on a steel Oyster bracelet fitted with a folding Oysterclasp and the Easylink comfort extension link. The screw-down crown helps hold the case to its 100 metre water resistance rating.
