Rolex Day-Date 40 228235-0055 40mm

The Rolex Day Date 40 reference m228235-0055 brings a contemporary gradient flair to the iconic presidential watch, a collection revered for prestige since 1956. Crafted entirely in Rolex’s exclusive 18 kt Everose gold—a patented rose gold alloy with platinum for unfading warmth—this 40mm timepiece features a mesmerizing slate ombré dial (colored center progressing to deep black edges) with faceted pink gold markers and the signature fluted bezel. Reviving an 1980s design relaunched in 2019, it offers subtle depth and modern elegance, perfect for those who seek refined innovation in luxury.

Design Highlights and Material Excellence

The m228235-0055 exudes quiet authority with its 40mm Oyster case—monobloc middle case, screw-down case back, and winding crown—all produced in-house from 18 kt Everose gold for superior purity and a soft, timeless rose glow. The fluted bezel in matching Everose gold catches light through its precise grooves, blending heritage functionality with aesthetic appeal.

The slate ombré dial is a technical highlight: a colored surface at the center transitions harmoniously to deep black at the edges via specialist-applied black lacquer, creating seamless gradient depth. Faceted, deconstructed Roman numerals and index hour markers in 18 kt pink gold add refined dimension and legibility. Chromalight-filled hands ensure discreet low-light readability. The full day spelling appears at 12 o’clock, the date at 3 o’clock benefits from the Cyclops magnification lens, and scratch-resistant sapphire crystal safeguards the surface.

Completing the ensemble is the President bracelet—debuted in 1956 exclusively for the Day-Date—with semi-circular three-piece links in 18 kt Everose gold for outstanding comfort and graceful drape, fastened by a concealed folding Crownclasp.
