I've worked with Paul Seregin at
http://www.baumeswissjeweler.com. I've only had him work on two watches so far but I was happy with the service and (not important for your case) he is sympathetic to vintage pieces.
I also talked to someone in the Shreve tower whose name I forget right now but they didn't want to take my job (the Valjoux I posted last week).
