Rolex Lady-Datejust 28 mm

Rolex's Lady-Datejust 28 mm, reference 279138RBR-0032, is cased in 18 ct yellow gold measuring 28 mm across. The bezel is set with 44 brilliant-cut diamonds, giving this dress watch its sparkle. A screw-down winding crown with the Twinlock double waterproofness system secures the case, and a sapphire crystal with a Cyclops lens sits over the date. The white dial is driven by calibre 2236, a self-winding Perpetual movement with a Syloxi hairspring in silicon and roughly 55 hours of power reserve. Rolex certifies it as a Superlative Chronometer. It rides on an 18 ct yellow gold Jubilee bracelet with five-piece links, closed by a concealed folding Crownclasp. The Twinlock crown also helps keep the case waterproof to 100 metres.
