I don't know if watchmaking is one of them, but there are a bunch of traditional crafts which are actually approaching a danger point because there aren't enough up-and-coming acolytes in the discipline to replace them, even though the craft still enjoys enough popular support to have a thriving economy.

Anecdotally, I see enough mechanical watches on wrists and in duty-free shops that I imagine there's enough of a pipeline there for at least one school. Much like vinyl records it doesn't appear to actually be going away even if it's superfluous.

Come to think of it, it makes sense; in this day and age, every industry is evolving so rapidly that the future remains quite uncertain.
