5 Facts about a Lange & Söhne

The new registration of A. Lange & Söhne would  not have been possible on 7 December 1990 because the office had already closed on that Friday. Walter Lange had deliberately chosen this day, because his great-grandfather, Ferdinand Adolph Lange, had registered his watchmaking on the same day 145 years earlier, in 1845. Today, Lange employs 700 people and is thus the largest employer in Glashütte. Long since 1997 itself. Up to and including the year 2013, the watchmaker, tool mechanic and engraver are still 150 watchmakers.

The longest built model – the Lange 1 – is since 1994 also the top product. With the eccentric dial construction and the unmistakable big date, Lange 1 became a huge success.No wonder that their design remains unchanged to this day. Since 1994, Lange has developed 49 own calibers, which essentially belong to the five watch families Lange 1 ,Saxonia, 1815, Richard Lange and Zeitwerk. Langewerk has succeeded in combining a genius range with Zeitwerk for a long time: it combines the classic design elements with a modern-looking digital display for hours and minutes. Another icon, beside Lange 1 and Zeitwerk, is the Datograph, introduced in 1999. The grand date and the auxiliary dials are arranged on its dial in an isosceles triangle. It was further developed with additional functions like perpetual calendar and tourbillon. The most complicated watch by A. Lange & Söhne is the 2013  Grand Complication. It has, among other things, a small and large chime, a rattrapante chronograph as well as a perpetual calendar and is limited to six copies. The production of a specimen lasts a whole year – the plant consists of 876 individual parts. With almost two million euros, the Grand Complication is one of the most expensive watches in the world.

The three-digit plate made of natural nickel silver characterizes a long caliber as well as the free-hand engraved balance claw, which makes every Lange watch unique. All works are assembled twice. First, it is assembled and regulated, then disassembled and polished and polished according to all rules of watchmaking, and then finally assembled. At the moment, Lange has 29 calibers in production, 26 of them with their own balancing coil. Since the launch of the double split in 2003, Lange has been expanding its self-developed balance coil.

Lange. To ensure good readability from all ranks, they designed a mechanism with two indicator wheels. The 66-part long date also consists of two separate display areas, a single disk and a ten-cross. Both are only 0.15 millimeters apart, while they revolve one on top of the other.
