Rolex Day-Date 40 40 mm 228348RBR-CHPSP Yellow Gold/Diamonds Champagne

The Rolex Day-Date is widely regarded as the most prestigious watch in the world, worn by presidents, heads of state, and visionaries since its introduction in 1956. It was the first wristwatch to display the day of the week spelled out in full—hence the name—and it has been crafted exclusively in precious metals from day one. The Day-Date 40, which expanded the case diameter to 40mm in 2015, brought the collection into the modern era while preserving every element of the original's regal character. Reference 228348RBR-CHPSP represents that legacy at its most opulent, pairing an 18k yellow gold case with a diamond-set bezel and a richly colored champagne dial.

The 40mm yellow gold case of the 228348RBR-CHPSP strikes a commanding presence without excess. Rolex crafts these cases from its own certified 18k yellow gold alloy, renowned for its consistent color and durability. The case architecture follows the classic Oyster construction—a philosophy of water-tight integration between case, crown, and caseback—and is rated to 100 meters (330 feet) of water resistance, a reassuring technical achievement for a watch of such decorative ambition.

The bezel of this reference is set with round brilliant diamonds, each selected and hand-placed by Rolex gem experts to ensure uniform brilliance and secure setting. This diamond-set bezel frames the champagne dial with a continuous arc of light that shifts and dances with every movement of the wrist. The champagne dial itself—warm, golden, and sophisticated—pairs perfectly with the yellow gold case, creating a monochromatic harmony that is anything but monotonous. Together, these elements make the 228348RBR-CHPSP one of the most visually striking configurations available in the entire Day-Date 40 lineup.

Powering the watch is a Rolex-manufactured automatic movement, the hallmark of Swiss chronometric precision. Rolex designs, produces, and regulates its calibers entirely in-house, and Day-Date 40 movements are certified as Superlative Chronometers—a standard that goes beyond the official COSC certification and guarantees precision to plus or minus two seconds per day after casing. This level of in-house mastery means the 228348RBR-CHPSP is as technically serious as it is visually spectacular.

On the wrist, the Day-Date 40 228348RBR-CHPSP is an experience unlike almost any other watch. The President bracelet—available exclusively on the Day-Date—features distinctive three-piece semi-circular links machined from solid 18k yellow gold and closes with a concealed fold-over Crownclasp. It conforms to the wrist with exceptional comfort and security, lending the watch a fluid, second-skin quality that belies its precious metal mass. This is a watch built to be worn, admired, and handed down.
