Our friends from Saxony, A. Lange & Söhne have decided to expand its range of dial and metals for its Datograph chronograph collection several months ago. Two new highly attractive models, one a Datograph Up/Down in 18K pink gold with black dial and the other, an 18K white gold Datograph Perpetual with grey dial are now available. The Datograph Perpetual —available in 18K pink gold and silver dial up until now— is now also available in 18K white gold with a grey dial making it even more appealing to watch connoisseurs. The argenté-colored subsidiary dials and deep-blue moon disc on the new model of the Datograph Perpetual stand out particularly clearly thanks to the dial’s subtle grey background. Since 2006, the name has represented a combination of a flyback chronograph and a perpetual calendar, which will not require correction until 2100. If this does ever become necessary, however, the calendar indicators can be advanced either individually or synchronously. Its chronograph can measure times to an accuracy of one-fifth of a second.
