After the World War and the new start of the watchmaking school in October 1945, only two marine chronometers were produced until 1951. The chronometer we have here is the one before last that was ever made at the school; altogether only 69 of these very fine instruments were built at the school between 1882 and 1951. It is very likely that Alfred Helwig was heavily involved in the making of this chronometer.
