The A. Lange & Sohne 1815
This overview is taken from alange-soehne.com, where you can find all the technical info.
The name 1815 stands for the birth year of Ferdinand A. Lange, who established Germany’s precision watchmaking industry in Glashütte. The design of the 1815 is characterised by traditional style elements: with blued hands, Arabic numerals and the railway-track minute scale, it is a worthy ambassador of Lange’s watchmaking heritage.
