Rolex Day-Date 40 228235-0036 40mm

The Rolex Day-Date 40 reference m228235-0036 represents the pinnacle of extravagant refinement and gem-setting excellence, a timepiece that has symbolized ultimate prestige since the Day-Date’s innovative debut in 1956. Fully crafted in Rolex’s exclusive 18 kt Everose gold—a patented rose gold alloy introduced in 2005 for lasting beauty—this 40mm masterpiece features a breathtaking diamond-paved dial with 10 baguette-cut diamond hour markers and a signature fluted bezel, creating an ocean of sparkle that captures light from every angle. Reserved for those who seek unparalleled opulence, it upholds the iconic instantaneous day and date displays in a design of pure, radiant luxury.

Aesthetic Excellence and Gem Craftsmanship

This reference shines with its 40mm Oyster case—a monobloc middle case, screw-down case back, and winding crown—all cast in-house from 18 kt Everose gold for exceptional alloy purity and a warm, enduring rose hue. The fluted bezel, a Rolex hallmark originally functional for waterproofing, gleams in matching Everose gold while providing a textured frame for the dial’s brilliance.

The diamond-paved dial is a horological triumph: hundreds of diamonds meticulously hand-selected by in-house gemologists and set with precision to the hundredth of a millimeter for perfect alignment, orientation, and uniform fire. Complemented by 10 baguette-cut diamonds as hour markers for refined contrast and legibility, it delivers exceptional intensity and sparkle. The day window at 12 o’clock spells the day in full, the date at 3 o’clock is magnified by the Cyclops lens, and subtle Chromalight ensures discreet visibility. Scratch-resistant sapphire crystal safeguards this mesmerizing surface.

The President bracelet—created in 1956 exclusively for the Day-Date—features elegant semi-circular three-piece links in 18 kt Everose gold for supreme comfort and fluidity, secured by a concealed folding Crownclasp.
