The "Richard Lange" pays tribute to the company founder Adolph Lange's first born son, Richard Lange (1845-1932). Richard was awarded 27 patents and utility model grants, and most importantly remembered as the spiritual father of the Nivarox spring.
The model revives the company's tradition of large observation pocket watches typical of the 1930s. These watches were used not only by renowned research institutes but also served as precision timekeeping instruments in scientific expeditions.
An "observation" watch is a high precision timepiece with large case and dial, characterised by high rate accuracy, enhanced legibility, and a certain degree of robustness. An observation wristwatch can be used to time scientific observations, as a navigational instrument and in military applications as a deck watch or an aviator's watch.
