The Rolex Day-Date 40 President 228235 represents the contemporary expression of one of Rolex's most prestigious complications. Released in 2015 as the 40mm Everose gold Day-Date, the 228235 succeeded the 228206 platinum generation in the modern Day-Date 40 lineup and introduced the in-house Caliber 3255 movement — Rolex's next-generation perpetual chronometer that set new standards for precision, autonomy, and reliability in the brand's manufacture calibers. The 40mm 18k Everose gold Oyster case carries the fluted 18k Everose bezel and the iconic President bracelet with the three-piece semi-circular links and concealed Crownclasp — the bracelet that has been synonymous with the Day-Date since 1956 and earned the model its presidential moniker. The standout feature is the slate ombré dial, a graduated slate-to-black gradient with applied 18k Everose gold Roman numerals that shifts subtly across the face of the watch depending on the angle of light. The day window appears at 12 o'clock, the cyclops-magnified date at 3. Powered by the Rolex Caliber 3255 self-winding movement with the patented Chronergy escapement for improved efficiency, paramagnetic Parachrom hairspring, Paraflex shock absorbers, and a 70-hour power reserve, the 228235 carries Superlative Chronometer certification to -2/+2 seconds per day. Sapphire crystal, screw-down Twinlock crown, 100 meters water resistance. Pre-owned.
