About an hour and a half, but I have some helpful stuff like a toolmaker's microscope to get the position of the steady pins, screw, and point where it should sit between two teeth, a CAD program I can import an image of an original jumper, trace, and then scale a traced drawing to size, and a little CNC machine that cuts out the part. The spring section still starts at around 0.15mm and gets thinned by hand to about 0.04 or 0.05, that's where the fun is.
I understand this seems to be a common problem related to the canon. Does anyone have any advice or a link to a manual or diagram that can explain how to fix this?
the watch gums fine and when setting it the hour and minute hands move correctly.
