I'm having a bit of a nightmare trying to find a UK based watchsmith who can repair/service my Seamaster Chrono (2594.52). Apparently not many people work on the 3301 movement, and fewer still have access to parts. I really don't fancy going near Omega with this. The wait time alone scares me. I've spoken to a couple of watchmakers I found through google, but no joy. Either no reply, or I end up finding horrid scary reviews on forums. Had my hopes pinned on watchguy.co.uk (christian), but he has no access to parts for the movement. Does anyone happen to have a recommendation? (worth a shot!)
Since you appear to have an early one, your going to need someone with a parts account so they can do the upgrades. have you tried Swiss Time Services?
