Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278271-0005, in steel and gold, is a chronometer sized for a woman's wrist. The case measures 31 mm across and carries a fluted bezel in gold. A sapphire crystal with a Cyclops lens sits over the date, and the rosé-colour dial is driven by the self-winding calibre 2236, a Rolex manufacture movement with a power reserve of approximately 55 hours. The screw-down crown protects the movement, and the watch shows a central seconds display alongside the date. It is fitted to a steel and gold bracelet with a folding Oysterclasp that includes the Easylink comfort extension link. Rolex rates the case to 100 metres of water resistance.
