Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278288RBR-0009, cased in 18 ct yellow gold with a diameter of 31 mm. The bezel is diamond-set, and the watch is set with diamonds, paired with a matching yellow gold President bracelet secured by a concealed folding Crownclasp. A white dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is calibre 2236, a self-winding mechanical movement with a power reserve of approximately 55 hours, and the watch carries Rolex's Superlative Chronometer certification. Complications are kept simple: central seconds and a date display. The screw-down crown, part of the Twinlock system, helps the case keep its 100 metre water resistance rating.
