Does anyone know of a watch repairman who can help with 12.68z, circa 1940? It's running and keeping decent time, but my chap here (London) was unable to get the flyback mechanism operating properly--I'm travelling to the States soon, so someone on that side of the pond would work as well. Once it's operating at full steam, I'll be looking to sell or trade it.
Consider contacting @aldo. This is his site: http://www.milwatchmaker.com/principale.php He seems to do great work on Longines chronographs. Another watchmaker on the forum is @Horlogerie. This is his sight: http://www.roberthoran.eu/ This is another place that deals with Longines chronographs: http://www.orologeria.com/index.html
Thanks for the suggestions. It's now back from Brendan Hoey (webwatchmaker), and running fantastically!
