To give you an example, I just sent back my Omega flightmaster 911 back for a second time to one of the most respected (and authorized!) North American vintage Omega repair shops. They fixed some things only to botch some other things. When repairing the botched things, other things were subsequently botched as well. Servicing is not magic, no matter who does it.
