I have a Speedmaster with a 321 movement that I purchased from a member on Omega Forums that now needs some work. Evidently, I need to have the internals ultrosonically cleaned due to some rust and the main spring replaced. Any estimates on what this should cost and/ or recommendations on where to send it? I live in the midwestern US. Thanks for the help.
World Time in San Jose, CA is top-notch. They're one of the very few watchmakers I've used who totally understand (and eliminate) chrono creep in the 321 movement. Might cost around $800 and take a couple of months.
