Regarding tools
Dear Francois,
It's interesting because I had wanted to address this issue elsewhere, but why not now...Steve Jobs, in a 1990 interview said
""I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. Humans came in with a rather unimpressive showing about a third of the way down the list....That didn't look so good, but then someone at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle and a man on a bicycle blew the condor away. "
There is really no way to make the machine that is a watch, without making other machines and tools (lathes, files, rose engines) first. It's by those tools that humans can make the marvelously small and mathematically accurate machines that we love so much here. Currently those machines are basically of three variants, computer controlled, cam/mechanically controlled, and hand controlled. All three are used at almost all manufacturers. Cam controlled machines are often used for small parts such as pinions, CNC for almost all mainplates, and rose engines for engraving. Even the ultimate "manu-facturer" Roger W. Smith uses machines that would qualify them as "non-manufactured" by your definition.
As we go on, it's highly likely that we'll see tool makers develop more CNC (computer controlled) machines that can do more and better, at which point we'll need to decide if anglage done by a machine that is more technically perfect than anglage done by a human hand holding a file is more or less desirable. This has already happened with Perlage (Panerai is at least one of the manufacturers that use a computer for the process), straight anglage (Glashutte uses a machine for this as well), and Geneva/Tokyo/Glashutte ribbing/waves.
I'll be glad to hear everyone's opinions on this.
