The February 2004 meeting of NAWCC chapter 168 Sydney members looked at the 400-day clock industry between the wars 1919-1939.  From 1900 to the beginning of the first WW was a boom period in 400 day clocks.  WWI interrupted production and only 5 of the 9 manufacturers continued -  Jahresuhrenfabrik, Gustav Becker (till 1926), Junghans, Kienzle (till 1926), Vosseler.  The post war Germany economy was a disaster with inflation and "made in Germany" was not popular.  However a new company Kundo started up in 1923.
