It's a Hugo genstein 3717 I obtained from another forum member. The reason why I'm hesistant for a normal watchsmith to do it is because supposedly the ETA 7750 was heavily modified to run to IWC standards. Now while I'm not entirely sure if thats just not hot air, I'd like it to run at IWC standards. Does anyone know how much a movement overhaul is at the IWC service center. I probably will just go to a private watch smith but was curious if anyone has taken this route.
