Presidential Legacy The Rolex Day-Date has long stood as a symbol of prestige and precision. Introduced in 1956, it was the first wristwatch to display both the date and the day of the week spelled out in full. Worn by world leaders and visionaries, the Day-Date continues to represent the pinnacle of Rolex craftsmanship and timeless design. Refined Precision This reference 228206, from 2015, features a 40mm case and is powered by the calibre 3255 automatic movement, offering a 70-hour power reserve. The smooth bezel and President bracelet with Crownclasp enhance its elegant profile, while the blue dial adds a contemporary touch to this enduring classic.
