Remark

Junghans 600.00; Detail fine adjustment

Unlike the successor models, the original form of the Junghans 600 has an eccentric fine adjustment with an additional joint.

The crown of the electromechanically driven movement has to be drawn only to position the hands. Since the watch does not have to be manually wounded, the Junghans designers could use an unusually shaped crown, which is well protected by the lower lug.
