Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278384RBR-0024, cased in steel and gold with a 31 mm diameter. The case is fitted with a diamond-set bezel and a screw-down crown, and the date sits under a Cyclops lens on a scratch-resistant sapphire crystal. Inside is the calibre 2236, a Perpetual mechanical movement that winds itself and carries a power reserve of around 55 hours. This is a chronometer, certified to Rolex's own standard after casing. The pink sunray dial pairs with a Jubilee bracelet in steel, closed by a concealed folding Crownclasp in steel and gold. Central seconds and an instantaneous date round out the functions. The screw-down crown holds this Datejust to a 100 metre water resistance rating.
