Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278241-0023, cased in steel and gold with a 31 mm diameter. The domed bezel tops a case fitted with a screw-down crown, and the dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the self-winding calibre 2236, a Rolex manufacture movement certified as a chronometer, with a power reserve of approximately 55 hours. The rosé dial is set with diamonds, and a central seconds hand joins the date as the watch's main functions. It is a chronometer built on a steel and gold bracelet closed with a folding Oysterclasp, which includes the Easylink comfort extension link. The screw-down crown, part of the Twinlock system, helps hold the case to its 100 metre water resistance rating.
