Rolex Day-Date 228236-0004 Black Diamond Dial 40mm Platinum Men’s Watch

The Rolex Day-Date 40 Ref. Case Shape: Round. 228236-0004 is crafted in 950 platinum and represents the blend of iconic design and modern Rolex engineering. With a striking bright black dial set with baguette-cut diamond hour markers, it merges understated elegance with bold presence.

The 40 mm platinum case features Rolex’s signature fluted bezel, lending the watch both texture and light play. The case construction uses the Oyster monobloc middle case, screw-down case back, and winding crown, ensuring robustness and water resistance up to 100 meters. The winding crown employs Rolex’s Twinlock double waterproofness system.

The bright black sunray dial is distinguished by 10 baguette-cut diamonds set in white gold—adding refined sparkle without overpowering purity. The day display is shown in full at 12 o’clock, with the date window at 3 o’clock under the Cyclops lens. The dial’s sunray finish captures light dynamically, enhancing depth and visual interest.

Inside is Rolex’s in-house Caliber 3255, a self-winding movement offering approximately 70 hours of power reserve and certified to Rolex’s stringent Superlative Chronometer accuracy of ±2 seconds per day after casing. It incorporates advanced features like the Chronergy escapement and Parachrom hairspring for improved efficiency, shock resistance, and magnetic field stability.

Completing the design is the platinum President bracelet, composed of semi-circular three-piece links that deliver both comfort and a stately look. The bracelet features a concealed folding Crownclasp for seamless aesthetics and ease of wear.
