Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 28 mm, reference 279381RBR-0021, has a 28 mm case in steel and gold. The case is built in Everose Rolesor, Rolex's term for the steel and gold combination, with a monobloc middle case and screw-down crown. A diamond-set bezel frames the white dial, which sits under a sapphire crystal with a Cyclops lens over the date. Inside is the self-winding calibre 2236, a Rolex manufacture movement certified as a chronometer, with a central seconds hand and instantaneous date. The watch is set with diamonds. A five-piece Jubilee bracelet in the same steel and gold combination closes with a concealed folding Crownclasp. The screw-down crown helps hold the case to its 100 metre water resistance rating.
