The Rolex Day-Date 40 reference 228236-0007 is a prestigious 40mm timepiece crafted entirely from 950 platinum. This model is distinguished by its bright blue sunray dial, which features a fine sunburst finish and applied 18k white gold Roman numeral hour markers. A defining characteristic of this specific reference is the introduction of the fluted bezel in platinum, a feat of engineering previously reserved for gold models due to the difficulty of machining the dense metal. The watch is paired with the iconic President bracelet, characterized by its semi-circular three-piece links and a concealed folding Crownclasp that maintains a seamless aesthetic around the wrist.
Powering the timepiece is the manufacture caliber 3255, a self-winding mechanical movement that offers a power reserve of approximately 70 hours and a precision of -2/+2 seconds per day. The watch features the collection’s signature complications, including the instantaneous day of the week displayed at 12 o’clock and the date at 3 o’clock, both adjustable via a secure rapid-setting system. The Oyster case construction, featuring a screw-down Twinlock crown and a scratch-resistant sapphire crystal with a Cyclops lens, ensures water resistance up to 100 meters.
General reviews of the 228236-0007 often emphasize its significant physical weight and the technical milestone represented by the platinum fluted bezel. Collectors and enthusiasts frequently highlight the bright blue dial as a striking yet sophisticated alternative to the traditional ice blue reserved for other platinum Rolexes. While the watch is lauded for its ultimate luxury status and refined proportions, some reviews note that its extreme density and high market value make it a substantial presence on the wrist that may be more suited for formal occasions than daily casual wear.
