I've had a similar experience with schaffhausen.It all started after I'd bought the very first,in Asia,new pilot chrono 43mm. After acquiring the watch from the IWC boutique in Kuala Lumpur,Malaysia,I arrived back to my house in Australia,with the watch still with its protective covering intact. When I came to unravel the layers of plastic from the watch and give it a proper visual inspection,as one does,over a coffee/tea,I noticed some small nicks in the case around the bezel area. I promptly phoned the salesman at the boutique to notify him of the problem. He assured me that it couldn't have happened during their handling of the watch. I didn't want a polish of the case because the marks were to close to the crystal,and the only real solution was to have the watch transported to schaffhausen.Anyway,to cut a long story short,the watch went to schaffhausen,via IWC in Sydney,Australia.Eight months later,I received a brand new,different serial number watch. I have to say that IWC in schaffhausen,or more specifically,those in the department responsible for warranty issues,were abysmal in their customer service. If it weren't for the help and assistance of IWC in Sydney,I would have given up on IWC altogether.
So,schaffhausen,I hope that some of you read this,because you still need to improve on your customer service.
