A rotary tool is a modern way of facilitating the process of anglage, it's certainly not what Philippe Dufour, Rexhep Rexhepi, Romain Gauthier, and other independent watchmakers employ. To clarify for the community, by hand in this instance refers more to the rotary tool still being guided by the human hand, leading to some of the characteristics presented here. I think the tooling and process overall is definitely price appropriate.
