Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 28 mm, reference 279381RBR-0007, comes in a 28 mm case of steel and gold. The bezel is diamond-set, and the dial is olive green with diamonds, viewed through a sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding mechanical movement with a power reserve of approximately 55 hours, certified as a chronometer. The screw-down crown protects the case, and the watch shows a central seconds hand and a date function. It is a jewellery watch as much as a chronometer, with the dial's stones set in 18 ct gold. The Jubilee bracelet, in matching steel and gold, closes with a concealed folding Crownclasp. Water resistance stands at 100 metres.
