Rolex Datejust 31 mm

Rolex's Datejust 31 mm ref. 278273-0018 is a women's model in steel and gold, measuring 31 mm across. The case wears a fluted bezel in gold and carries a screw-down crown, with a sapphire crystal set over a dark grey dial that is itself set with diamonds. Inside runs the self-winding calibre 2236, a Rolex manufacture movement certified as a chronometer, with a central seconds hand and a date function. Power reserve stands at approximately 55 hours. The dial's diamond-set finish gives the watch its gem-set character alongside the chronometer rating. A five-piece Jubilee bracelet in steel and gold closes on a concealed folding Crownclasp. The screw-down crown helps hold the case to its 100 metre water resistance rating.
