I've got a circa 1967/8 Speedmaster with a Cal-321 movement. I need a service - it's been a while and while it keeps time but the chrono function doesn't work. Who in North America could I trust to do the work. I was once given the name of a guy in Canada - but he wasn't doing it anymore. I'm in Chicago if that makes a difference.
Try contacting @Archer who contributes to this forum. He's a very experienced watchmaker who specialises in Omega and is based in Canada
How 'bout Manny @Govberg Watch Repair in Philadelphia. Very satisfied with what he did for my Cal.321 Speedy. Very reasonable turn-around time and and at a reasonable price Call Customer service and ask for Israel.
i've heard good things about Chronodeco, and i believe they're based in Chicago too. but i have also heard there's a long waiting list. but supposedly economical and very fast once the watch is actually in their possession. i think i am plagiarizing an old instagram post belonging to @ahantel at this point...
