At the beginning of the 20th century they ventured into America and Langendorf were imported by American Swiss Watch Co who in 1915 were reported out of business. An advertisement in 1916, which showed a picture of there factory in Langendorf, said that they employed 1,500 workers and produced 3,000 pieces daily. By 1920 they were also producing alarm clocks.

In 1924 there was a branch at Lommiswyl and the following year an agency in Le Chaux De Fonds.

Listing continue until at least 1986.
