The Rolex Day-Date 40 reference 228345RBR-0002 is an ultra-luxury timepiece crafted from 18k Everose gold, a proprietary rose gold alloy developed by Rolex to preserve its luster over time. The 40mm Oyster case is distinguished by a fixed bezel set with 48 diamonds and a screw-down Twinlock crown that ensures water resistance up to 100 meters. This specific model features a striking diamond-paved dial adorned with 10 baguette-cut diamond hour markers and the iconic Cyclops lens over the date aperture. It is paired with the signature President bracelet, characterized by semi-circular three-piece links and a concealed folding Crownclasp.
Powering the watch is the caliber 3255, a self-winding mechanical movement entirely developed and manufactured by Rolex. This movement offers a power reserve of approximately 70 hours and features a blue Parachrom hairspring and Paraflex shock absorbers for enhanced resistance to magnetism and impact. As a Superlative Chronometer, it is certified to maintain a precision of -2/+2 seconds per day after casing. The complications include instantaneous day and date displays with a rapid-setting feature, as well as a stop-seconds function for precise time setting.
General reviews of the 228345RBR often highlight its exceptional gem-setting and the prestige associated with the all-gold and diamond configuration. It is frequently praised for its refined aesthetics and the comfort provided by the President bracelet, though its bold appearance is generally noted as being suited for formal or special occasions rather than daily wear. While collectors value its high craftsmanship and status as a flagship model, some critics point out that the high-set diamond dial and bezel significantly increase the price compared to more understated iterations within the Day-Date collection.
