If you've noticed I keep referring to the fact that the Swiss watch industry is kept together by a series of suppliers who produce the necessary parts that go into watch movement. There are zero totally vertically integrated watch makers in Switzerland even today. The whole system of manufacturing could be halted if just one supplier stopped supplying materials or parts. This is why Mr. Hayek instructed Nivarox to produce its own metal for the balance springs. Originally sourced from a metal producer in Germany, there was just too much fear that if the supplier didn't want Nivarox as a client anymore (which of course could happen on a whim), the entire industry would supper as watches could not be produced. Hayek's ongoing mantra to Nivarox was "product, product, product, product.
