Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278344RBR-0013, cased in steel and gold, measures 31 mm across. The domed bezel is set with diamonds, adding sparkle around a silver dial. A sapphire crystal with Cyclops lens sits over the date, and the hands and indices carry luminous treatment for legibility. Inside is the calibre 2236, a self-winding movement certified as a chronometer with roughly 55 hours of power reserve. Central seconds and a date display round out the functions, and the screw-down crown adds a further layer of protection. The watch is fitted to a steel bracelet with a folding Oysterclasp, complete with the Easylink comfort extension link. That same crown, together with the case construction, keeps the watch water resistant to 100 metres.
