Are you thinking about flashing? as in a flasher that wears a coat?

Flashlights can be custom built too, just like watches. From alu, copper, brass and Ti, almost all the base materials(includes pvd coating too) for watches are also used on flashlights. It's a smaller group of geeks compared to what the watch group has but it's almost the same(on my mind).
