Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278274-0012, is cased in steel and white gold at 31 mm across. The case pairs with a fluted bezel in gold, a signature detail on this model. A Cyclops lens sits over the date on the scratch-resistant sapphire crystal, and the silver dial carries luminous hands and indices for legibility. Inside is calibre 2236, a self-winding Rolex movement certified as a chronometer, with a power reserve of approximately 55 hours. The screw-down crown adds a further layer of protection against moisture and dust. A five-piece Jubilee-style steel bracelet closes with a concealed folding Crownclasp. Rolex rates the case to 100 metres.
