Junghans and the Hamburg American Clock Company (H.A.C)

A brief history -

and why has a Junghans J80 the marks of H.A.C.?

Paul Landenberger, who was born in 1848 in Ebingen (Germany) and 1939 died in Schramberg (Germany), was employed from 1868 at Junghans than being responsible for the purchase and distribution of watches of American production.

In 1871 he was elevated to the technical director of the company Junghans and married a year later, the daughter of Erhard Junghans (he died in 1870) named Frida Junghans. Dissatisfied with the nonexistent chances to climb up the stairs in the company, Landsberger emerged in 1875 from Junghans and founded the company Landsberger & Lang and thus became a competitor for Junghans, especially since he still resided in Schramberg and he also still took many employees from his former company.

Forced by financial difficulties, he had to ask for a loan even at Junghans. After another, even legal disputes with Junghans finally a settlement was reached in 1883 and the original company Landsberger & Lang was converted into a corporation named "Hamburg-Amerikanische Uhrenfabrik (HAU)". Landsberger apparently had good relations with the company Deuerer & Kaufmann in Hamburg, that probably earlier sold its watches. Landsberger still remained in dispute with Junghans, whether for family reasons or because of disputes about markets is unclear.

In 1925 the number of employees of HAU was approximately 2,200 people. A key product of HAU were the ATO clocks whose license was acquired in 1929 by Haller & Benzing after their closure. Forced by the losses due to inflation in 1925 a community of interests between Junghans, the Vereinigte Freiburger Uhrenfabriken and the HAU founded in 1927. The plan to grow stronger economically was braked abruptly by a massive loss of equity of the companies involved. Finally Junghans took over the other two as the strongest company in 1930. Paul Landenberger became board member of Gebrüder Junghans AG. In 1939 the name "HAU" no longer performed.

The HAU was mainly known for the production of alarm clocks, and small clocks for tables.

Just a short time (exactly how long is unclear) were transiently produced clocks that bore both names (Junghans and HAU).

Until about a year ago I was not known that the HAU (or H.A.C. = Hamburg American Clock Company; for the English market) not only produced clocks but also launched wrist watches.

To me a Junghans J97 (production 1940-1952) with 7 stones and lever movement was known. It was marked on the dial with the Arrow Cross, including H.A.C. and at 6 "FOREIGN". Also on the movements is in addition to the 8-pointed star and the "J" with "unghans" the well known "FOREIGN" visible.

In a later surfaced watch that the Junghans J80 or Junghans 680.70 harbored, I still thought at first to a Marriage, but after I had seen better pictures of this watch, it was clear that Junghans actually also built wrist watches with the HAU.
