Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278241-0010, has a case measuring 31 mm in steel and gold. The case is finished with a domed bezel and holds a Cyclops lens over the date on the sapphire crystal. Inside is the calibre 2236, a self-winding mechanical movement with a power reserve of approximately 55 hours, and Rolex certifies the watch as a chronometer. The rosé-coloured dial shows central seconds and a date display, and the crown is a screw-down type. This is a women's watch built on a Jubilee-style bracelet in matching steel and gold, closed by a concealed folding clasp. The screw-down crown helps hold the case to its 100 metre water resistance rating.
