I’m into watch repair..so I’m thinking that you are going to want to find some of the larger collets to start ( depending on the size of clocks you are planning to repair ).
Maybe start with .30 and go up in size ?
I’m thinking that you will eventually also want a larger lathe..a small “commercial” style but others with more clock experience can help you there..
Best of luck..write back if you think I can help you somehow ??
