That's pretty neat! The book I posted is really neat, but it is very intense and pretty technical.
@kop316 I'm starting with traditional, larger clocks, at least in terms of learning/research. Not sure yet if that will expand into a full hobby, or expand beyond that into watches as well.
@kop316 The book you posted definitely looks like the one to get if I want to expand into watches though!
@kop316 I do have a vintage Gruen Veri-Thin I got as a present with rubies at 12, 3 and 9. It runs for a bit (sometimes a few minutes, sometimes an hour or two) then stops. I imagine at the very least it needs a cleaning, but it would not be something I would tackle as a first project!
