Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278271-0006, comes in steel and gold with a 31 mm case. The bezel is fluted, a signature Rolex detail. A sapphire crystal with a Cyclops lens sits over the date. Inside is the self-winding calibre 2236, a Rolex manufacture movement with 55 hours of power reserve and Superlative Chronometer certification. The rosé-colour dial shows a central seconds hand and a date display, and the screw-down crown adds a further layer of protection. The steel and gold bracelet closes with a concealed folding Crownclasp. Water resistance reaches 100 metres, thanks in part to that screw-down crown.
