Notes
1954-
In 1955 the PUW 60/61 was regarded as the only German movement with chronometer capability. Probably the reason was that the movements were tested by the traditionally responsible Deutsche Hydrographische Institut Hamburg, while Junghans chronometers were tested by the PTB in Braunschweig (PTB = Pysikalisch-Technische Bundesanstalt = German Federal Institute for Phyical and Technical Standards).
