The Day-Date was originally designed to be a precious instrument for everyday use. Thanks to a watchmaking prowess that was unprecedented at the time. The Day-Date was the first self-winding, waterproof chronometer wristwatch to display, in addition to the date, the day of the week spelt out in full, in two separate windows. Both change simultaneously at midnight. The Day-Date is a Prefect balance between elegance and technical excellence. Instantly recognizable, its unique design has forged its identity, as the Day-Date is only produced in the precious metals; Yellow Gold, White Gold, Everose Gold and Platinum. At its launch in 1956, the Day-Date was the only watch with a semi-circular window at 12 o’clock displaying the day of the week spelt out in full. With its specially-designed President bracelet available only in precious metal. The days on the Day-Date are written differently depending on the language. Using most writing systems as Latin, Arabic, Cyrillic, Hebrew, Japanese, Chinese ideograms and even the Ge'ez alphasyllabary. This example has an English Day-wheel. This Rolex Day-Date 36 'Champagne Diamond Dial' was sold for the first time in June 1990. This Day-Date is made out of 18k Yellow Gold and is fitted with a President bracelet which conceals the Crown clasp. The Reference 18238 has a double quickset function, wich means it can not only set the date with the quickset function but also the day. This means the Day and the Date can be set separately.  This Rolex Day-Date 36 is in amazing condition and comes with the original Rolex Warranty Papers and box. Furthermore, the watch has been serviced by our watchmaker, and therefore it comes with one year of warranty.
