The model version in pink gold features an argenté-coloured dial crafted from solid silver. Launched in 2013, the 1815 RATTRAPANTE PERPETUAL CALENDAR marked a milestone in A. Lange & Söhne’s more recent history: no less than seven chronograph calibres had previously been crafted by the Saxon manufacture. Equipped with a specially developed movement, it united three of the most elaborate complications while maintaining the classic, elegant design of the 1815 watch family. The outstanding timepiece excels in the measurement of short and long distances and thanks to its eponymous complications, the 1815 RATTRAPANTE PERPETUAL CALENDAR sets standards in both short-time measurement and the display of calendar periods. The rattrapante function of the 1815 RATTRAPANTE PERPETUAL CALENDAR represents one of the greatest horological challenges. In addition to the conventional functions of a chronograph, this sophisticated complication has the ability to measure intermediate times and comparative times as well as determining minimum and maximum values in the course of one minute. Since the balance wheel of the manufacture calibre L101.1 beats with six semi-oscillations per second, the stopped times can be recorded with an accuracy of one sixth of a second. High-precision readings are assured thanks to the additional graduation on the peripheral minute scale. ——— Rostovsky Watches 9454 Wilshire Blvd, Beverly Hills, CA 90212, United States Phone: +1 310-205-7960 Mail: chad@rostovskywatches.com
