Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278243-0028, cases the watch in 31 mm of steel and gold. The domed bezel sits above a white mother-of-pearl dial set with diamonds, and a Cyclops lens over the date magnifies the day's date beneath the sapphire crystal. Rolex's self-winding calibre 2236 drives the watch, offering approximately 55 hours of power reserve and central seconds display. The movement carries chronometer certification, and the screw-down crown adds a further layer of protection against moisture. A steel and gold bracelet closes with a concealed folding Crownclasp. This is a dress watch built for daily wear, and the case holds a 100 metre water resistance rating.
