Rolex Oyster Perpetual 28 mm

Rolex Oyster Perpetual 28 mm, reference 276245RBR-0001, is cased in 18 ct rose gold measuring 28 mm across. The case follows Rolex's monobloc Oyster architecture, with a screw-down crown and a sapphire crystal over the dial. This is a diamond-set watch through and through: the bezel is diamond-set, and the white mother-of-pearl dial carries diamond-set hour markers along with luminous hands and indices. The self-winding calibre 2232 drives the watch, offering a power reserve of approximately 55 hours, and Rolex certifies it as a chronometer. It rides on a rose gold Oyster bracelet with three-piece solid links, closed by a folding Oysterclasp with a comfort extension link. That clasp keeps the case sealed to its rating of 100 metres.
