Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 28 mm, reference 279138RBR-0014, comes in an 18 ct yellow gold case measuring 28 mm across. The bezel is set with 44 brilliant-cut diamonds, giving this a place among Rolex's gem-set watches. A Cyclops lens sits over the date on the scratch-resistant sapphire crystal. Inside is calibre 2236, a self-winding chronometer movement with a power reserve of approximately 55 hours. The champagne-colour dial shows a central seconds hand alongside the date, and the screw-down crown carries a Twinlock double waterproofness system. It is fitted to a President bracelet in yellow gold, closed with a concealed folding Crownclasp. That screw-down crown, together with the case construction, keeps the watch waterproof to 100 metres.
