Chronometer testing institute
The chronometer testing institute was from 1875 to 1945 an institution for review of marine chronometers , pocket watches and clocks in Hamburg . It was subordinate to the German Seewarte .
history
George Rümker had proposed a chronometer testing institute to the Hamburg Senate when the Deutsche Seewarte was founded. It entered service as Division IV in 1875. Formally, the institute belonged to the Deutsche Seewarte, but it was set up in the garden of the Hamburg observatory because the observatory had the astronomical possibilities of determining the time . The director of the observatory was also head of the chronometer testing institute.
As the checks and the comparative measurements expanded considerably, a new building was built near the sea observation point. On April 1, 1899, the Chronometerprüfungsinstitut became fully part of the Deutsche Seewarte.
