This German heritage stuff is nonsense. Its a cheap Chinese watch. That being said, its a fairly good one.
Good points: Nice over all appearance, mine is extremely accurate ( you may not be as lucky as automatic mechanical watches can vary in their acccuracy). If you have the tools you can regulate it or have a jeweler do it for you if necessary.
Not so good points: The instructions say to wind it 10 to 15 turns each morning before wearing it. I thought - why bother ? - its self winding. It stopped running later that day while on my wrist. Maybe Im not typical because I have a desk job so my wrist doesnt move too much. So now I wind it a bit before wearing it and it doesnt stop.
The crown is hard to grasp to turn because its quite small.
Forget trying to see the sub- dials if you're getting older like me. They are just too small.
Bottom line: the good points outweigh the bad and its a great value.
