This guy is obviously an adherent of George Daniels. His story is fascinating. He produced likely one of the only significant inventions in mechanical watches in the last century, the coaxial escapement. The book shown in the OP is wonderful and here's a documentary:

Daniels' apprentice and now watchmaker Roger W. Smith has carried on making watches with his escapement and like Kikuno-San makes all of the components by hand and in-house.

It's probably worth clarifying why it's obvious that he was an adherent of George Daniels. In his book, and in every interview I've seen of him, he speaks at length about the value of a watch maker being able to make every component in a watch. Listening to him talk about how he learned every aspect of the trade in his is fascinating.
