If you look at it from a distance servicing a movement is not expensive at all. A €200 service for a €2000+ watch seems ok. But a €200 service for a €200 rep seems insane. It all is a mater of perspective. The price of the watch is irrelevant to the work that is put into servicing a movement. Some buy reps, wear them and if they break they will buy a new one. Others want to keep and maintain their rep as they would a genuine, in their eyes the rep becomes genuine basically. A personal choise. You can find some interesting discussions in my signature.
And all the discussions about pricing is irrelevant. I can do a 'full service' for €30 bucks. Does that mean I will? No. Like I mentioned earlier. Buy the craftsman and not the service. Everybody can give you a quote on a full service but you need to be confident you will get what you pay for! IMO a lot of so called watch makers or local jewelers cut corners and only a few will give your watch a true tear down.
