A Masterpiece of Design and Craftsmanship

The Day-Date 40 m228398tbr-0036 dazzles with its 40mm Oyster case, including a monobloc middle case, screw-down case back, and winding crown—all cast in Rolex’s in-house 18 ct yellow gold for flawless purity and a captivating warm glow. The bezel, set with meticulously selected diamonds, elevates the traditional fluted design into a jewel-encrusted halo of light refraction.

The diamond-paved dial is a pinnacle of gem-setting artistry: hundreds of diamonds hand-set with precision to the hundredths of a millimeter, aligned for optimal orientation and brilliance, creating a seamless pavement of fire. Enhanced by 10 baguette-cut diamonds as hour markers, it ensures legibility amid the splendor. The day spells out fully at 12 o’clock, the date at 3 o’clock is magnified by the Cyclops lens, and subtle Chromalight on select elements provides discreet luminescence. Scratch-resistant sapphire crystal safeguards this mesmerizing surface.

Exclusive to the Day-Date, the President bracelet in 18 ct yellow gold features semi-circular three-piece links for luxurious comfort and fluidity, secured by a concealed folding Crownclasp.
