The Rolex Day-Date 40 mm, reference 228398TBR-0007, is cased in 18 ct yellow gold with a diameter of 40 mm and a thickness of 12 mm. The bezel is diamond-set, complementing the champagne-colour dial. A Cyclops lens sits over the date on the scratch-resistant sapphire crystal.

The watch shows the day and date, both set instantaneously, and the crown screws down for added security.
