I have a question why is it Sinn who sells a large amount of (Great! btw) watches in the U.S. has no service center here? The last time I sent a Sinn watch to Germany it cost $95 to ship via UPS . They were the only carrier who would insure the watch for full value. All other carriers would only insure to $500. I feel $95 just to get it there with some security is a bit much.
I think all Sinn owners should start E mailing Sinn to ask them to authorize and train a USA sevice center in serviceing AR watches. Other great watch companys have U.S. service centers.
