Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278344RBR-0024, has a 31 mm case in steel and gold. A domed, diamond-set bezel frames the dark grey dial, and the screw-down crown sits beneath a scratch-resistant sapphire crystal with a Cyclops lens over the date. Calibre 2236 drives the watch, a self-winding movement with 55 hours of power reserve and Superlative Chronometer certification. The dial carries a central seconds hand and an instantaneous date. Diamonds set into the bezel give the watch its jewellery-like presence without disturbing its practical function. A steel bracelet closes with a concealed folding Crownclasp in steel and gold. That same crown, screwed down against the case, keeps the watch water resistant to 100 metres.
