Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278344RBR-0019, cased in steel and gold. The case measures 31 mm and carries a domed, diamond-set bezel. A sapphire crystal with Cyclops lens sits over the date, and the mint green dial shows luminous hands and indices. Inside is the self-winding calibre 2236, a chronometer with roughly 55 hours of power reserve. The screw-down crown adds a further layer of protection to the movement. Diamonds are set into the case, and the watch is fitted to a steel Oyster bracelet with a folding clasp and Easylink extension link. Water resistance reaches 100 metres, courtesy of that screw-down crown and case construction.
