The Rolex Day-Date 40 reference m228398tbr-0043 is the ultimate expression of lavish elegance and masterful gem-setting, a watch that has defined supreme accomplishment since the Day-Date’s debut in 1956. Crafted entirely in radiant 18 ct yellow gold, this 40mm jewel features a captivating white mother-of-pearl dial set with 10 baguette-cut diamonds and a diamond-paved bezel, where natural iridescence meets dazzling brilliance for extraordinary exclusivity. Destined for those who embrace the extraordinary, it preserves the iconic instantaneous day and date displays amid a tapestry of natural beauty and precious stones.

Masterpiece of Design and Craftsmanship

The Rolex Day-Date 40 m228398tbr-0043 mesmerizes with its 40mm Oyster case, comprising a monobloc middle case, screw-down case back, and winding crown—all cast in Rolex’s in-house 18 ct yellow gold for unmatched purity and a warm, timeless luster. The bezel, fully paved with meticulously selected and hand-set diamonds, creates a radiant frame with flawless alignment and orientation for maximum light dispersion.

The white mother-of-pearl dial is a natural marvel: sourced from shells without artificial coloring, each piece unique in its subtle hues and structure, displaying organic variations that ensure no two watches are identical. Enhanced by 10 baguette-cut diamonds as hour markers for refined contrast and sparkle, it offers exceptional legibility. The day appears in full at 12 o’clock, the date at 3 o’clock is enlarged by the Cyclops lens, and discreet Chromalight provides subtle glow where needed. Scratch-resistant sapphire crystal protects this iridescent masterpiece.

The President bracelet, created exclusively for the Day-Date in 1956, features semi-circular three-piece links in 18 ct yellow gold for luxurious comfort and seamless flow, secured by a concealed folding Crownclasp.
