[Modell 3001 neu  --  G 08.05.2010]
1. Winding Wheel not turning (jammed) and therefore its not winding for the watch to work.
2. Other Service if required.
Please note: 
Watch was returned once before for the same problem (winding wheel came off) when it was still under Warranty. It seems that these watch suffer from this problem ??? 
I trust
