Rolex Lady-Datejust 28 mm

Rolex's Lady-Datejust 28 mm, reference 279384RBR-0015, comes in steel and white gold and measures 28 mm across. The case has a screw-down crown and a dark grey dial under a scratch-resistant sapphire crystal with a Cyclops lens over the date. The bezel is diamond-set, and the watch is set with diamonds elsewhere as well. Inside is the calibre 2236, a self-winding mechanical movement with a Syloxi hairspring and Paraflex shock absorbers, giving around 55 hours of power reserve. As a chronometer, it carries Rolex's certification for precision after casing, and the dial also shows a central seconds hand and a date. A steel Jubilee bracelet closes with a concealed folding Crownclasp. Rolex rates the case to 100 metres of water resistance.
