The Rolex Datejust 126234 is the 36mm interpretation of Rolex’s most enduring dress watch, and the bright blue Roman dial is one of its most striking configurations. This distinguished timepiece features a 36mm Oyster case in White Rolesor, Rolex’s pairing of Oystersteel and 18k white gold, with a monobloc middle case, a fluted white gold bezel, and a screw-down Twinlock crown. The captivating bright blue dial is set with applied white gold Roman numerals and matching hands, delivering a rich, saturated contrast that shifts noticeably as the light moves across the surface. Powered by the Rolex Calibre 3235, a self-winding mechanical movement certified as a Superlative Chronometer to within minus two and plus two seconds per day, the 126234 guarantees exceptional precision and reliability. This movement features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, along with a power reserve of approximately 70 hours, an instantaneous date with rapid setting, and a stop-seconds function for precise time setting. An Oystersteel Jubilee bracelet with five-piece links completes the watch, secured by a folding Oysterclasp with the Easylink 5mm comfort extension for on-the-fly adjustment. Water-resistant to 100 meters and protected by a sapphire crystal with the signature Cyclops lens, the Datejust 126234 pairs the most classic proportions Rolex makes with a genuinely modern movement.
