Welcome to the forum and course, I’ll be looking forward to seeing some of your collection of clocks. If you need any help, just ask and many hands will happily come to your aid 
Hmm, tools, that is an addiction in itself 😆 I’m a watch guy but the only thing that differs is the size, so I would say a good set of screwdrivers/pliers/hammer/punch set is a basic must have.. I’m sure the clock boyz will chime in with their recommendations..
