zenith service in US
first post here. my 2001 class el primero (02.0500.400) had fully wound down. i started winding it and heard/felt a <click>. i wound it a couple more times and realized it wasn't going to start. broken mainspring i'm guessing. there's a 1916 company AD in my area (baltimore). do they service it locally or will it be sent to the zenith service center in NJ? should i just send it to NJ? thanks.
