Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 279178-0031 is a 28 mm case in yellow gold. The fluted bezel is gold as well, and the case pairs with a sapphire crystal fitted with a Cyclops lens over the date. Inside runs calibre 2236, a self-winding chronometer movement with 55 hours of power reserve. The dial is diamond-paved, set with diamonds, and the date sits at its familiar station with a central seconds hand. A screw-down crown secures the case, part of the Oyster architecture Rolex builds into this model. The watch is fitted to a President bracelet in yellow gold, closed with a concealed folding Crownclasp. Water resistance reaches 100 metres.
