Collection: Day-DateCase size: 40mmMovement: 3255

Rolex Day-Date 40 mm, reference 228345RBR-0026, measures 40 mm across in Everose gold. The case stands 12 mm thick and carries a diamond-set bezel around a white mother-of-pearl dial set with diamonds. A Cyclops lens sits over the date on the scratch-resistant sapphire crystal. Inside is the calibre 3255, a self-winding chronometer movement with roughly 70 hours of power reserve. The dial shows the day and date along with central seconds, and the screw-down crown protects the movement from moisture. The President bracelet, in matching Everose gold, closes with a concealed folding Crownclasp. Waterproofness is rated to 100 metres thanks to the Twinlock crown system.
