On December 7, 1990, on the exact day 145 years after the firm was founded by his great-grandfather, Ferdinand Adolph Lange, Walter Lange re-registered the brand A. Lange & Söhne in its old hometown of Glashütte. Ferdinand Adolph had originally launched the company as a way to provide work to the local population. And shortly after German reunification in 1990, that is exactly what Glashütte needed as well.
The company quickly regained its outstanding reputation as a robust innovator and manufacturer of classically beautiful watches. A. Lange & Söhne uses only mechanical, manually wound manufacture calibers or automatic winders finished according to the highest Glashütte standards. The movements are decorated and assembled by hand with the fine adjustment done in five positions. The typical three-quarter plate and all the structural parts of the movement are made of undecorated German silver: the balance cock is engraved freehand. The movements combine equal parts traditional elements and patented innovations, like the Lange large date, the SAX-O-MAT with an automatic “zero reset” for the seconds hand, or the patented constant force escapement (Lange 31, Lange Zeitwerk). Of the company’s forty-six calibers, twenty-six are currently in production, and two-thirds of those have their own balance spring.
A. Lange & Söhne manufactures only a few watches, but they are memorable. One star is the Lange 1 Tourbillon Perpetual Calendar equipped with an automatic movement and featuring a month ring or a stop-second mechanism for extremely accurate setting. The tourbillon is visible through the transparent case back. So Lange could comply with its ideal of an uncluttered dial. As for the Grand Lange 1 “Lumen,” it reveals the Lange designers as genuine artists with Superluminova.
