The back cover of the shown red line variant (golden, printed indexes and numbers) has a number, the rest is the same as the also shown watch (black self-winding and chrome, applied indices and numbers).
The dimensions of the base platines are identical to the manual winding version. There is little information to the watch shown.
The automatic version is also presented on the company's own museum Junghans in Schramberg and is designated as a Junghans J55. Further information on cooperation with Westclox: The Westclox-Mystery
