Rolex Day-Date 40 228235-0056 40mm

The Rolex Day-Date 40 reference m228235-0056 is a captivating fusion of natural beauty and luxurious craftsmanship, a timepiece that has embodied prestige and innovation since the Day-Date’s debut in 1956. Crafted entirely in Rolex’s patented 18 kt Everose gold—a rose gold alloy designed to retain its warm hue indefinitely—this 40mm masterpiece features a unique white mother-of-pearl dial set with 10 baguette-cut diamonds and the signature fluted bezel, where organic iridescence meets precise gem-setting for one-of-a-kind sophistication. Ideal for those who appreciate exclusive, natural artistry, it delivers the iconic, instantaneous day and date displays in a truly personal design.

Aesthetic Excellence and Unique Materials

The m228235-0056 enchants with its 40mm Oyster case—monobloc middle case, screw-down case back, and winding crown—all cast in-house from 18 kt Everose gold for exceptional purity and a soft, enduring rose glow. The fluted bezel in matching Everose gold, a Rolex signature, reflects light elegantly through its precise grooves.

The white mother-of-pearl dial is a natural wonder: sourced untreated from shells, each dial varies subtly in colour, intensity, and structure, ensuring no two are identical—truly a unique piece on every wrist. Elevated by 10 baguette-cut diamond hour markers for brilliant contrast and legibility, it shimmers with organic mystery. 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 discreet Chromalight provides subtle low-light visibility. Scratch-resistant sapphire crystal safeguards this iridescent canvas.

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