Rolex Datejust 31 mm

Rolex's Datejust 31 mm ref. 278278-0028 comes in 18 ct yellow gold with a case diameter of 31 mm. The silver dial is set with diamonds, with a large VI marked out in 11 stones, and sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. A fluted bezel in gold finishes the case, and the screw-down crown carries the Twinlock system. Inside is the calibre 2236, a self-winding Perpetual movement with a Syloxi hairspring and around 55 hours of power reserve; Rolex certifies the watch as a Superlative Chronometer. Central seconds and the date round out the display. A President bracelet in yellow gold closes with a concealed folding Crownclasp. It stays water resistant to a depth of 100 metres.
