Biography
A. Lange & Söhne, Saxon Precision Watchmaking Lange & Söhne is a world-famous German watch manufacturer, founded in 1845 by Ferdinand Adolph Lange (1815-1875). As a talented and visionary watchmaker, he aims to create watches of the highest quality. He established his factory in Glashütte, a small town located in the Saxony region of Germany, which would become an important watchmaking centre over the years. From the beginning, Lange sought to develop the watch industry in his region, which was then economically disadvantaged. With the support of the Royal Government of Saxony, he established a watchmaking school and trained young local craftsmen and master watchmakers to create exceptional timepieces. Over the decades, A. Lange & Söhne became a successful company and gained a reputation for the quality and precision of its watches which are appreciated for their exceptional craftsmanship, meticulous finishing, and horological complications, in particular Grande and Petite Sonnerie, tourbillons and Grandes Complications. The manufacture developed numerous technical advances in watchmaking, in particular the pendant winding mechanism, the split-seconds chronograph and self-winding with a peripheral oscillating weight. A unique pocket watch, serial number 42 500, is the most complicated watch ever made by the brand. Delivered in 1902, it combines perpetual calendar, chronograph, minute repeater and Grande and Petite Sonnerie. However, during World War II and the subsequent Soviet occupation of East Germany, the company was nationalized and forced to cease operations. After the reunification of Germany in 1990, Walter Lange (1924-2017), the great-grandson of Ferdinand Adolph Lange, dared to resume activities and relaunched “A. Lange & Söhne” with the financial support of Richemont Group. Since then, A. Lange & Söhne has regained its place among the most prestigious watch brands in the world. It stands out for its constant quest for excellence, its attention to details and its spirit of innovation. A. Lange & Söhne watches are manufactured in-house and are renowned for their technical complexity, high-quality movements combined with horological complications. Handcrafted by highly skilled watchmakers and craftsmen who master complex techniques such as hand engraving, enamelling and engine-turning, the timepieces produced by the manufacture are distinguished by their elegant classic aesthetics. Among its greatest successes are brand icons such as the “Lange 1”, with the first Grande Date in a mass-produced wristwatch, and the “Zeitwerk” with a jumping-hour dial. Complications such as the “Zeitwerk Minute-repeater”, the “Datograph Perpetual Tourbillon” or the “Triple Split” embody the aspiration of the manufacture to always take its art, rich in a long tradition, to new heights. In 2014, Walter Lange received the “Special Jury Prize” from the Grand Prix d’Horlogerie de Genève (GPHG) for his efforts to restore the city of Glashütte to a world-class watchmaking centre. Today, A. Lange & Söhne watches are highly prized by collectors and watch enthusiasts who appreciate the combination of tradition, technical sophistication and timeless design. The brand continues to create exceptional watches, perpetuating the legacy of Ferdinand Adolph Lange and his relentless quest for watchmaking perfection. -- Key dates • 1845: Ferdinand Adolph Lange founds the A.
