Remark

The movement shown above is produced after 1936 because the escape wheel cock is not separat, but before 1949/50 as from this time the shock absorber has been installed.

The Junghans J80/2 and later the J80/5 had the finest movement fitting and awarded the title "Meister". The movements were equipped with a ribbing, but also movements of the caliber J80 were provided with ribbing, which are not delivered in "Meister" -execution.
