Rolex Datejust 31 mm

Rolex's Datejust 31 mm, reference 278381RBR-0023, comes in a steel and gold case measuring 31 mm across. The bezel is diamond-set, and a Cyclops lens sits over the date on the sapphire crystal. Inside is the calibre 2236, a self-winding movement offering roughly 55 hours of power reserve. This is a chronometer, certified to Rolex's Superlative standard, with central seconds and a date function driven by the screw-down crown. The rosé dial is set with diamonds, giving the watch a jewelled finish typical of the Datejust line. It is fitted to a matching steel and gold bracelet with a folding Oysterclasp and an Easylink extension link for added comfort. The screw-down crown, part of the Twinlock system, helps keep the case rated to 100 metres.
