I did a quick search but could not really find a good answer. Is there a recommended watch repair service that you would use to replace the mainspring on a Landeron 48 Chronograph? I have had mixed results with my local watchmaker on some of the more vintage stuff I own, and I am not really comfortable having him have a go at it. So I wanted to see who's had some experience with this before and what your recommendations are?
Thanks for the help!
