Hmmm, just stopped after 5 years? It probably doesn't need anything more than a good servicing.
I don't have any suggestions for a rep friendly watchmaker in SoCal, but I'm sure they're out there. Should be $150 or less to have it done.
Good luck!
Maybe some of the Cali members could help you out? h_u, LegendOfSpeed, chinkiechunkie, etc., where are you guys?
