Rolex Lady-Datejust 28 mm

Rolex Lady-Datejust 28 mm reference 279383RBR-0018 measures 28 mm across in a case of steel and gold. The case is fitted with a diamond-set bezel and a screw-down crown, part of the Twinlock waterproofness system. A sapphire crystal with a Cyclops lens sits over the date, and the silver dial is read against central seconds. Inside is the calibre 2236, a self-winding movement certified as a chronometer with a power reserve of approximately 55 hours. The watch is set with diamonds on the bezel, and Rolex classes it among its Lady-Datejust models as a women's watch set with gemstones. It comes on a steel and gold bracelet with a folding Oysterclasp and Easylink extension link. The screw-down crown helps hold the case to its 100 metre water resistance rating.
