The Rolex Day-Date 40 Ref. 228238 is the quintessential symbol of horological prestige, representing the pinnacle of Rolex’s watchmaking excellence in a commanding 40mm 18K yellow gold Oyster case. This iconic “President’s watch” is distinguished by its fluted 18K yellow gold bezel, a signature Rolex design element that originated as a functional feature and has since become an aesthetic hallmark of the collection. The champagne-colour sunburst dial showcases the masterful brushing technique that creates delicate light reflections, shifting subtly with wrist movement to reveal its characteristic warm glow, and is adorned with applied yellow gold index hour markers or Roman numerals, which are filled with luminescent material for excellent legibility. At the heart of this masterpiece beats the revolutionary in-house automatic Caliber 3255, a Superlative Chronometer certified movement that delivers an exceptional 70-hour power reserve, enhanced precision, and Rolex’s patented Chronergy escapement for superior efficiency. The watch is completed by the legendary President bracelet, created in 1956 for the Day-Date’s launch, featuring semi-circular three-piece links crafted from solid 18K yellow gold and a concealed Crownclasp for seamless elegance. With a water resistance of 100 meters (330 feet) and protected by a scratch-resistant sapphire crystal with Cyclops lens over the date aperture, this 2015-introduced reference is the ultimate expression of prestige and timeless design, favored by world leaders and discerning collectors alike. Key specifications: 40mm 18K yellow gold case; fluted yellow gold bezel; champagne sunburst dial; Caliber 3255 automatic movement; 70-hour power reserve; President bracelet; 100m water resistance; sapphire crystal with Cyclops.
