Ref. 228345RBR-0012
Rolex Day-Date 40, reference 228345RBR-0012, measures 40 mm across in rose gold. The case is 12 mm thick and carries a diamond-set bezel, with the Cyclops lens over the date sitting on a scratch-resistant sapphire crystal. Inside is calibre 3255, a self-winding movement with a 70-hour power reserve and Rolex's Superlative Chronometer certification. The white dial shows the day and date along with a central seconds hand, and the watch is set with diamonds on the bezel. It rides on a rose gold President bracelet fitted with a concealed folding Crownclasp. This is a dress watch built with jewellery-grade finishing rather than tool-watch intent. The screw-down crown keeps the case waterproof to 100 metres.
