Rolex Day-Date 40 228235-0002 40mm

The Rolex Day-Date 40 reference m228235-0002 offers a rich, inviting take on the presidential icon, a collection synonymous with prestige since 1956. Executed entirely in Rolex’s exclusive 18 kt Everose gold—a patented rose gold alloy with platinum for permanent warmth—this 40mm timepiece features a deep chocolate sunray dial paired with the iconic fluted bezel, delivering subtle light reflections and sophisticated depth. Perfect for those who appreciate warm, understated luxury, it preserves the signature instantaneous day and date complications in a design of enduring appeal.

Design Highlights and Material Excellence

The Rolex Day Date m228235-0002 exudes refined presence 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 unmatched purity and a soft, timeless rose glow. The fluted bezel in matching Everose gold, originally functional for waterproofness, now serves as a light-catching aesthetic signature.

The chocolate dial is a showcase of finishing mastery: delicate sunray brushing creates outward grooves that diffuse light for a subtle, varying glow depending on wrist position. The chocolate color is applied using Physical Vapour Deposition or electroplating, followed by a light varnish for protection and enhanced vibrancy. Chromalight-filled hands and markers ensure long-lasting blue luminescence for discreet 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 look 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.
