I have a very nice old Waltham Vanguard that has served me well. I was just admiring it last night, today I found it had quit running. I had recently bought a watch repair tool kit because I wanted to start doing some of my own maintenance. I got the watch apart. And I was correct that the mainspring was broke. But I couldn't get the mainspring housing apart, long story short I ended up ruining the mainspring housing getting it apart.
So now I need a usable housing and a new mainspring. Any ideas on where to source these parts?
