Rolex Day-Date 40 40 mm 228396TBR-SLVQMRP Platinum/Diamonds Silver

The Rolex Day-Date has carried the unofficial title of the world's most prestigious watch since its introduction in 1956, and the 40 mm generation—launched in 2015 as a refinement of the classic 36 mm Day-Date—elevated that status by offering a larger, more contemporary presence on the wrist without sacrificing a single element of the original's authority. Reference 228396TBR-SLVQMRP sits at the very top of this storied line, combining a solid platinum 950 case, an extravagant baguette diamond bezel, and a silver quadrant Roman dial into one of the most coveted luxury watches available for sale anywhere in the world.

Platinum is the rarest metal Rolex uses for the Day-Date, reserved exclusively for the 40 mm case and positioned above yellow, white, and Everose gold in the brand's own hierarchy. The 40 mm case measures a commanding 40 mm in diameter and is crafted entirely from Rolex's certified 950 platinum, lending the watch a cool, weighty gravitas that even 18 ct white gold cannot replicate. The case architecture follows the classic Oyster form with its signature fluted middle case, downward-lugged profile, and screwdown Triplock crown.

The bezel of the 228396TBR-SLVQMRP is set with individually hand-selected baguette diamonds, a labor-intensive process in which each rectangular stone must be precisely calibrated and matched for color and clarity before being channel-set around the circumference of the case. The result is a continuous circuit of brilliant white light that frames the dial and elevates this reference far beyond a standard Day-Date. Inside, the silver quadrant Roman dial features the characteristic sector-style guilloche finishing divided into quadrants, with bold Roman numerals at the hours—a combination that reads as simultaneously classic and architectural, perfectly complementing the platinum and diamond exterior.

Power comes from an automatic movement housed within the hermetically sealed Oyster case. The Day-Date 40 platform is driven by one of Rolex's modern in-house calibers featuring a Parachrom hairspring, Paraflex shock absorbers, and a bidirectional self-winding rotor, delivering the high level of precision and reliability for which Rolex is globally recognized. The watch is presented on Rolex's President bracelet, a three-piece link design created exclusively for the Day-Date in 1956 and here rendered in matching platinum, completing what is arguably the most cohesive and magnificent expression of the Day-Date concept available.
