  • Do you buy some of the parts or make everything from scratch?

  • „from scratch“ that’s an elastic term, related to the hairspring: when I make my Tourbillons I use blue old hairsprings made for watchmakers who in former times had to repair pocket watches. These hairsprings were offered in different sizes, ordered by size in small paper bags. You have to decide, to find the right elasticity, the length and so on. Then you must make and fit a suitable brass collet and so on. Consider there are still more rules to observe, but YouTube gives me only 10 min.
