Rolex Oyster Perpetual Day-Date "Blue Degrade Diamond Dial " ref.18238 The Rolex Oyster Perpetual Day-Date reference 18238 is a distinguished and luxurious timepiece that epitomizes the brand's dedication to precision, craftsmanship, and elegance. Introduced in the late 1980s, the reference 18238 is part of the iconic Day-Date collection, which has been a symbol of prestige and status since its debut in 1956. Known as the "President" watch, the Day-Date is celebrated for its unparalleled sophistication and its unique combination of day and date display. The reference 18238 features a 36mm case crafted from 18k yellow gold, exuding an air of opulence and timeless appeal. The case is meticulously finished with a combination of polished and brushed surfaces, showcasing Rolex's exceptional attention to detail. The signature fluted bezel, also in 18k yellow gold, adds a touch of refinement and serves as a hallmark of the Day-Date collection. One of the most striking features of the reference 18238 is its captivating blue degrade dial with diamond indexes. The degrade dial, also known as a gradient or sunburst dial, transitions from a deep blue at the center to a darker shade at the edges, creating a mesmerizing effect that catches and reflects light beautifully. The diamond hour markers are set in 18k yellow gold, adding an extra layer of luxury and brilliance to the watch. Each diamond is carefully selected and set, ensuring exceptional quality and sparkle. The day and date functions are prominently displayed on the dial, with the day window at 12 o'clock and the date window at 3 o'clock, both magnified by the iconic Cyclops lens. This practical innovation not only enhances legibility but also underscores the watch's functionality and convenience. Powering the reference 18238 is the Rolex Caliber 3155, a self-winding mechanical movement renowned for its precision and reliability. The Caliber 3155 is a certified Swiss chronometer, meeting the highest standards of accuracy and performance. It features a quickset mechanism, allowing for easy adjustment of both the day and date functions. The movement operates at a frequency of 28,800 vibrations per hour (4 Hz) and provides a power reserve of approximately 48 hours. The watch is paired with the iconic President bracelet, crafted from 18k yellow gold and featuring semi-circular, three-piece links that offer exceptional comfort and a secure fit. The President bracelet is fitted with a concealed Crownclasp, which not only enhances the bracelet's seamless appearance but also provides a secure and adjustable closure.
