The Rolex Day-Date 40 reference 228348RBR-0001 is a prestigious 40mm timepiece crafted from 18k yellow gold, representing a modern evolution of the classic President watch introduced in 2015. The case is defined by a factory-set diamond bezel featuring 48 brilliant-cut diamonds, which surrounds a sunray bright black dial. This dial is further elevated by ten baguette-cut diamond hour markers set in 18k gold. The watch is paired with the iconic three-piece link President bracelet, also in 18k yellow gold, which utilizes a concealed folding Crownclasp to maintain a seamless aesthetic across the wrist.
Technically, the watch is powered by the Manufacture Rolex caliber 3255, a self-winding mechanical movement that offers a power reserve of approximately 70 hours. This movement incorporates the high-performance Chronergy escapement and Paraflex shock absorbers, achieving a precision of -2/+2 seconds per day. The signature complications of the Day-Date include the instantaneous day of the week displayed in an arc at 12 o’clock and the date at 3 o’clock, which is magnified by the scratch-resistant sapphire crystal’s Cyclops lens. Its Oyster case, equipped with a Twinlock screw-down crown, ensures water resistance up to 100 meters.
General reviews of the 228348RBR-0001 frequently emphasize its commanding presence and the high level of craftsmanship involved in its gem-setting. Collectors often highlight the 40mm proportions as a more balanced alternative to the previous Day-Date II, noting that the integrated President bracelet provides exceptional comfort. While praised for its status as the ultimate “power watch,” some reviewers note that the extensive use of diamonds and yellow gold makes it a very overt statement piece, primarily suited for formal or dress occasions rather than understated daily wear.
